The Biodiversity of Blackflies (Diptera: Simuliidae) in Brazil: New Distribution Records and Updated Checklist.

Currently, according to the most recent Simuliidae World Inventory, there are 97 valid species of blackflies recorded in Brazil, some of which act as vectors for zoonoses such as human onchocerciasis and mansonellosis in the northern and central-western regions of the country. Meanwhile, other species can cause serious socioeconomic problems due to the nuisance of female bites. Therefore, accurate knowledge of their distribution is crucial for the development and implementation of successful preventive strategies. With this aim, this study reviewed and updated the geographical distribution of the blackfly fauna throughout the Brazilian states. The data were compiled from three main sources: geographic information of material deposited at the Simuliidae Collection of the Instituto Oswaldo Cruz (CSIOC-IOC), a comprehensive review of scientific literature, and online biodiversity databases. We present a total of 71 new distribution records of 38 different Simuliidae species for 24 Brazilian states. Neither of these sets of records has been included in the Simuliidae World Inventory. Consequently, an updated Brazilian Simuliidae checklist, comprising a total of 98 valid species, is presented, highlighting these new distribution records. We also discuss six dubious records for the country and the implications of this updated data for the Simuliidae species richness of Brazil, its states, and biomes. This information is essential for future studies in the taxonomy, systematics, and biogeography of this family in Brazil.

Fossil Collection at the Zoology Museum of the University of Concepción: enhancing understanding of Chile's past biodiversity.

Background: The digital inventory of paleontological material stored in Chilean museums is highly relevant as it increases accessibility to information, both locally and over long distances, while reducing wear and tear on specimens caused by physical manipulation. The Fossil Collection database of the Museum of Zoology of the University of Concepción (UCC_MZUC_FOS) includes 144 records, with the main representatives being marine invertebrates of the Bivalvia, Echinoidea and Gastropoda classes. Notable species include Encopecalderensis, Hemiasterwayensis, Zygochlamyspatagonica and Retrotapesexalbidus, most of which come from important Chilean fossil sites. Material was collected between 1970 and 2017, with a large portion of it being donated and identified by Professor Emeritus Hugo I. Moyano and Dr. Alberto Larraín. Although the specimens contained in the resource offer basic collecting information, they substantially contribute to sharing knowledge on the fossils kept in the museums throughout the country, while providing data on their distribution. New information: This resource corresponds to the first publication of data on faunal fossils from a museum collection in Chile on the Global Biodiversity Information Facility (GBIF) platform, thereby enhancing the understanding and documentation of Chile's paleontological heritage and its national biodiversity.

Coleópteros acuáticos (Insecta: Coleoptera) depositados en la Colección Zoológica de la Universidad del Tolima (CZUT) / Aquatic beetles (Insecta: Coleoptera) deposited in the Zoological Collection of the University of Tolima (CZUT)

Introducción: Los Coleópteros acuáticos exhiben una gran importancia dentro de los cuerpos de agua, no solo por su papel en la cadena trófica, sino también por su papel como bioindicadores de la calidad del agua. A pesar de la gran importancia que representan, los estudios a nivel específico o sobre su riqueza y distribución son pocos en el departamento del Tolima y en general del país, por lo que surge este estudio. Objetivo: Ampliar el conocimiento sobre la biota de coleópteros acuáticos en el departamento del Tolima. Materiales y métodos: Se tuvo como base el material depositado en la Colección Zoológica de la Universidad del Tolima (CZUT), se realizó la determinación taxonómica y se estableció la distribución del material en las diferentes cuencas y municipios del departamento del Tolima. Resultados: Se encontraron 16 familias, 22 subfamilias y 61 géneros, siendo las familias Dytiscidae (13 géneros), Elmidae (13 géneros) y Staphylinidae (9 géneros), por otra parte, estos resultados representaron el 39,6% de los géneros reportados para Colombia y el 78,2% para el departamento del Tolima. El material evaluado proviene de 14 de las 18 cuencas mayores del departamento, siendo Saldaña, Totare y Prado las que mostraron la mayor riqueza y abundancia de Coleópteros acuáticos. Conclusión: Finalmente, y teniendo en cuenta lo anterior, se evidencia que las colecciones biológicas representan importantes repositorios de biodiversidad, dado que son pocas las ocasiones en las que se puede realizar la revisión y el aprovechamiento de un material con un amplio rango temporal, altitudinal y espacial, por lo que, seguir realizando estudios que involucren estos espacios es vital para conocer y dilucidar la biodiversidad del país.

Aquatic Coleoptera exhibit great importance within bodies of water, not only for their role in the food chain but also as bioindicators of water quality. Despite the great importance they represent, studies at a specific level or on their wealth and distribution are few in the department of Tolima and the country in general, which is why this study arises. Objective: Expand knowledge about the biota of aquatic beetles in the department of Tolima. Materials and methods: The material deposited in the Zoological Collection of the University of Tolima (CZUT) was used as a basis, the taxonomic determination was carried out and the distribution of the material in the different basins and municipalities of the department of Tolima was established. Results: 16 families, 22 subfamilies, and 61 genera were found, the families being Dytiscidae (13 genera), Elmidae (13 genera), and Staphylinidae (9 genera), on the other hand, these results represented 39,.6% of the genera reported for Colombia and 78.2% for the department of Tolima. The material evaluated comes from 14 of the 18 major basins of the department, with Saldaña, Totare, and Prado being those that showed the greatest richness and abundance of aquatic Coleoptera. Conclusion: Finally, and taking into account the above, it is evident that biological collections represent important repositories of biodiversity, given that there are few occasions in which the review and use of material with a wide temporal and altitudinal range can be carried out. and spatial, therefore, continuing to carry out studies that involve these spaces is vital to knowing and elucidating the country's biodiversity.

From species descriptions to diversity patterns: the validation of taxonomic data as a keystone for ant diversity studies reproducibility and accuracy.

Research findings in natural sciences need to be comparable and reproducible to effectively improve our understanding of ecological and behavioural patterns. In this sense, knowledge frontiers in biodiversity studies are directly tied to taxonomic research, especially in species-rich tropical regions. Here we analysed the taxonomic information available in 470 studies on Brazilian ant diversity published in the last 50 years. We aimed to quantify the proportion of studies that provide enough data to validate taxonomic identification, explore the frequency of studies that properly acknowledge their taxonomic background, and investigate the primary resources for ant identification in Brazil. We found that most studies on Brazilian ant diversity (73.6%) explicitly stated the methods used to identify their specimens. However, the proportion of papers that provide complete data for the repository institutions and vouchered specimens is vanishingly small (5.8%). Additionally, only 40.0% of the studies consistently presented taxon authorities and years of description, rarely referencing taxonomic publications correctly. In turn, the number of specialists and institutions consulted for ant identification in Brazil has increased in the last years, along with the number of studies that explicitly provide their taxonomic procedures for ant identification. Our findings highlight a shift between generations regarding the recognition of taxonomy as fundamental science, deepening our understanding of biodiversity.

First evidence of ranavirus in native and invasive amphibians in Colombia.

Ranaviruses can cause mass mortality events in amphibians, thereby becoming a threat to populations that are already facing dramatic declines. Ranaviruses affect all life stages and persist in multiple amphibian hosts. The detrimental effects of ranavirus infections to amphibian populations have already been observed in the UK and in North America. In Central and South America, the virus has been reported in several countries, but the presence of the genus Ranavirus (Rv) in Colombia is unknown. To help fill this knowledge gap, we surveyed for Rv in 60 species of frogs (including one invasive species) in Colombia. We also tested for co-infection with Batrachochytrium dendrobatidis (Bd) in a subset of individuals. For Rv, we sampled 274 vouchered liver tissue samples collected between 2014 and 2019 from 41 localities covering lowlands to mountaintop páramo habitat across the country. Using quantitative polymerase chain reaction (qPCR) and end-point PCR, we detected Rv in 14 individuals from 8 localities, representing 6 species, including 5 native frogs of the genera Osornophryne, Pristimantis and Leptodactylus, and the invasive American bullfrog Rana catesbeiana. Bd was detected in 7 of 140 individuals, with 1 co-infection of Rv and Bd in an R. catesbeiana specimen collected in 2018. This constitutes the first report of ranavirus in Colombia and should set off alarms about this new emerging threat to amphibian populations in the country. Our findings provide some preliminary clues about how and when Rv may have spread and contribute to understanding how the pathogen is distributed globally.

The Genus Thionia Stål, 1859 (Hemiptera: Auchenorrhyncha: Issidae) in Colombia: Highlighting the Value of Entomological Collections.

Entomological collections represent a key source of information about the biological heritage of a country. However, the taxonomy and knowledge of many arthropods from megadiverse countries are underrepresented in these natural history collections as is the case with several planthoppers of the suborder Auchenorrhyncha. Issidae are fulgoromorphs distributed worldwide, except the poles and Greenland. Despite this ubiquity, Colombian planthoppers remain very poorly known and studied. Our objective was to provide the first consolidated records and distributional data for Colombian Issidae. We used reports of the representative genus Thionia deposited in biological collections in Colombia. In addition, we linked voucher specimen information and Olson's life zones showing an inter-Andean valley and Eastern Andean Cordillera distribution within Colombia. Our survey of Colombian biological collections revealed 55 individuals of the genus Thionia Stål, 1859 (53 adults, 2 immatures [nymphs]), which were collected by different methods; however, many of those records may be opportunistic. This genus (and its species) needs further study, with systematic and ecological revision, as is the case with other terrestrial Colombian hemipterans. Our consolidated records represent an advance to the knowledge of Issidae (and Thionia specifically) for the Neotropics and Colombia in particular, and a baseline for further study of distributional and biogeographic patterns of the suborder Auchenorrhyncha.

Massive invasion on a Triatominae insectarium (Hemiptera: Heteroptera: Reduviidae) by Attagenus fasciatus (Thunberg, 1795) (Coleoptera: Dermestidae: Attageninae)

ABSTRACT Background: Triatominae are vectors of the protozoan Trypanosoma cruzi, the causative agent of Chagas disease. This study aims to report an infestation on Triatominae colonies by a beetle, previously identified as a pest. Methods: The management of these colonies should be improved to maximize their usefulness, and factors that may cause harm to them should be avoided as much as possible. Results: This is the first report on a coleopteran infestation on living Triatominae colonies worldwide. Conclusions: The present record provides an important warning to researchers who maintain insectaries in general, especially those who rear triatomines, to carry protective measures against such invasions.

Taxonomic revision and additional comments of some bats (Mammalia, Chiroptera) reported from Bolivia, with an updated checklist based on voucher material with verified identities

We review the taxonomic identities of museum specimens of three bat species previously reported from Bolivia. We comment on some erroneously reported taxa, or taxa either not represented by voucher materials or based on insufficient data (including acoustic detections) to verify their taxonomic affinities. As result of this review, the list of bat species known to occur in Bolivia is updated to eight families and 133 species, unlike the nine families and 146 species of previous lists. Some recommendations for future research and a brief historical revision of bat inventories in the country are included.

Use of geospatial analyses to address snakebite hotspots in mid-northern Brazil - A direction to health planning in shortfall biodiversity knowledge areas.

Knowing the distribution of venomous snakes of medical importance is essential to identify areas at risk for snakebites. Thus, we used an integrative approach based on the application of geographic distribution data of venomous snakes, species distribution modeling (SDM), spatial organization of snakebites, and information on human population density for mapping the potential distribution of snakes and identifying areas at risk of snakebites in the state of Maranhão (mid-northern Brazil). From a compiled database of venomous snake records deposited in biological collections and the literature, we predict the potential distribution of venomous snakes in Maranhão, a state whose diversity and geographic distribution of venomous snake species are poorly known. With this, we constructed potential distribution maps for each venomous snake species with at least one occurrence record within state boundaries, as well as generalized maps by family (Viperidae and Elapidae) and the total number of venomous snakes in Maranhão State. We also obtained data on the number of snakebites recorded in each municipality of Maranhão over a decade (2009-2019) and we ran a Generalized Linear Model to test for relationships between the number of venomous snakebites, the area of occurrence of snakes, and human population density. We obtained 1046 records of venomous snake species for Maranhão, represented by 17 viperid and elapid species. Most of the records were from Viperidae (mostly Bothrops atrox and B. marajoensis) and were concentrated mainly in the Amazon of the northern portion of the state. The models showed accurate predictive performance for all modeled species. The entire area of Maranhão exhibits environmental conditions for the occurrence of venomous snakes, with higher suitability indices in the northern region, in the Amazon rainforest. The number of snakebites was positively correlated with the interaction between high-risk areas (i.e., greater distribution of venomous snakes) and human population density. Our study is a pioneer in using species distribution modeling in mid-northern Brazil to address the scarcity of data on snakebite-causing species, directly contributing to the theme of neglected tropical diseases of the World Health Organization.

Herbarium collection of the Pontificia Universidad Católica de Valparaíso (PUCV), Chile.

Background: This database gathers 10,721 specimens, belonging to 2,578 species from the Chilean vascular flora (angiosperms, gymnosperms and pteridophytes) deposited in the Herbarium of the Pontificia Universidad Católica de Valparaíso (PUCV) in Chile. The PUCV botanical collection was started by the renowned botanist Otto Zöllner and represents a major natural historical legacy for central Chile, with decades of information represented through preserved specimens. This collection is currently deposited in the Curauma campus of the PUCV. This digitisation effort is part of the PUCV's endeavour to mobilise its biological collections and make them freely available through GBIF, encouraging national and international researchers to generate new knowledge, based on this invaluable heritage, which is a silent witness of the vast plant diversity that once existed in Chile and that is now vanishing due to anthropogenic drivers. New information: The database provides occurrence records from 10,721 specimens of vascular flora held in the PUCV Herbarium, representing 2,578 species, 914 genera and 177 families. Each record includes data on taxonomy, geographic distribution, elevation and collection information (e.g. date of collection, legitimavit and determinavit of specimens, general observations). The database serves as a repository containing records from past decades on the diversity and distribution of plant species, mainly from the Chilean Mediterranean biodiversity hotspot.

Ants of Ecuador: new species records for a megadiverse country in South America

ABSTRACT Despite its small territory Ecuador hosts a remarkable biological diversity. Paradoxically, its prominent insect richness has been poorly studied and is usually underestimated in biodiversity inventories. Ants are a major component of such richness. With the aim of promoting myrmecological research, we present 20 new ant records for the country belonging to nine genera and six subfamilies. The species Tapinoma ramulorum inrectum Forel is recorded for the first time in South America. We provide brief taxonomic diagnoses and general comments for all species. Our results expand on the records of Formicidae species previously informed for Ecuador and stress the importance of scientific reference collections as biodiversity repositories.

Coleção de Vetores de Tripanosomatídeos (Fiocruz/COLVET) held at the institution Fiocruz Minas in Brazil: diversity of Triatominae (Hemiptera, Reduviidae) and relevance for research, education, and entomological surveillance.

The Coleção de Vetores de Tripanosomatídeos (Fiocruz/COLVET), Minas Gerais, Brazil, stands out as one of the most important collections of blood-sucking triatomines, the vectors of Trypanosomacruzi that causes Chagas disease. The aim is to describe the collection and the services it provides to support scientific research, educational activities, and entomological surveillance between 2013-2019.The data associated with the specimens held in Fiocruz/COLVET is available from the Sistema de Informação sobre a Biodiversidade Brasileira (SiBBr). These specimen metadata were analyzed and either tabulated or plotted on graph and maps. The records of services provided by the collection between 2013-2019 were also categorized and analyzed. There are 12,568 triatomine specimens deposited in the collection that belong to 77 species and 11 genera, from 15 American countries. Of the ~ 65 species of triatomines found in Brazil, 38 (57.6%) are present in the collection, including specimens from all biomes and all but three Brazilian states. The occurrence of Triatomacostalimai, Triatomalenti, Rhodniusnasutus, and Panstrongyluslenti apparently collected beyond their known distribution ranges are reported and discussed. The collection provided 168 services, supporting educational activities (41.7%), scientific research (35.7%), and regional/national entomological surveillance of triatomines (22.6%). Between the years 2014 and 2020, the number of biological specimens deposited in the Fiocruz/COLVET repository increased from 4,778 to 12,568 triatomine specimens. In addition to its great value to biodiversity conservation, the collection is of great importance because of its support of research and educational activities, and contributions to entomological surveillance, and, therefore, to public health.

Accediendo al pasado: uso de especímenes de colección como fuentes de información genética para el género Bombus (Hymenoptera: Apidae) / Accessing the past: use of collection specimens as sources of genetic information for the genus Bombus (Hymenoptera: Apidae) in Colombia

Introducción: Recientemente ha tomado relevancia el uso de especímenes de museo como fuente de información genética para desarrollar estudios que resuelven preguntas taxonómicas, ecológicas, demográficas y evolutivas a diversas escalas temporales y geográficas. Sin embargo, material genético obtenido a partir de ejemplares depositados en colecciones biológicas es poco usado, debido al deterioro natural del ADN preservado en dichos ejemplares, de manera que la obtención de material genético de calidad es demandante en términos de tiempo y dinero. Objetivo: Usando material de museo, identificar una secuencia mini-barcode que pueda ser empleada en la determinación taxonómica, y que a su vez suministre información que permita la estimación de relaciones filogenéticas de especies del género Bombus. Métodos: Se estandarizó el protocolo de extracción de ADN a partir de la extremidad mesotoracica derecha y/o una muestra de músculo torácico de 96 especímenes depositados en la colección LABUN entre 7 y 38 años atrás. Las diferentes combinaciones de oligonucleótidos evaluadas permitieron amplificar fragmentos de 152 a 407 pares de bases (pb) del gen mitocondrial Cytochrome Oxidase I (COI). Usando como plantilla un grupo de 31 secuencias amplificadas a partir de especímenes recolectados recientemente, los fragmentos obtenidos de los especímenes del museo fueron ensamblados y analizados en un marco filogenético. Además, se realizó un análisis de red de haplotipos para evaluar en detalle las relaciones entre los haplotipos mitocondriales resultantes. Resultados: Se determinó un mayor éxito de extracción de ADN a partir de muestras de extremidad depositadas a partir del año 1982.Entretanto, la amplificación exitosa de fragmentos de más de 300 pares de bases (pb) se logró principalmente en muestras depositadas en fechas posteriores a 1999, lo que indica una mayor integridad del material genético recuperado de individuos de 19 años de recolección en adelante. Aunque todos los fragmentos evaluados pueden ser empleados como mini-barcode, solo con uno se obtiene una topología similar a la observada con el fragmento completo. Se detectó una gran variacion genética, particularmente al interior de las especies Bombus atratus y B. funebris, en las que se reveló una clara estructura filogeográfica. Conclusiones: Se obtuvieron nuevas secuencias de códigos de barras mediante extracción de ADN y protocolo de amplificación de muestras de museos. Además, se generó nueva información sobre la variabilidad genética intraespecífica, detectando la presencia de haplotipos mitocondriales únicos que podrían constituir Unidades Significativas Evolutivas sujetas a conservación. Dicha información es de vital importancia para formular estrategias de conservación para estos polinizadores en Colombia.

Introduction: The use of museum specimens as a source of genetic information to develop studies that resolve taxonomic, ecological, demographic, and evolutionary questions at various temporal and geographic scales, has recently become relevant. However, genetic material obtained from specimens deposited in biological collections is not used frequently due to the natural deterioration of the DNA preserved in these specimens. Getting quality genetic material is demanding in terms of time and money. Objective: By using museum material,to identify a mini-barcode sequence that can be used in the taxonomic determination and provides information that allows the estimation of phylogenetic relationships of species of the genus Bombus. Methods: The DNA extraction protocol for museum samples was standardized using the mesothoracic right leg and / or a sample of thoracic muscle of 96 specimens deposited in the LABUN collection between 7 and 38 years ago. Different combinations of oligonucleotides allowed to amplify fragments from 152 to 407 base pairs (bp) of the mitochondrial gene Cytochrome Oxidase I (COI). Using as a template a group of 31 sequences amplified from recently collected specimens, the fragments obtained from the museum specimens were assembled and analyzed in a phylogenetic framework. Additionally, a haplotype network analysis was performed in order to evaluate in detail the relationships between the resulting mitochondrial haplotypes. Results: The greatest success of DNA extraction was achieved from limb samples deposited since the year 1982 on. Meanwhile, successful amplification of fragments longer than 300 base pairs (bp) was achieved mostly in samples deposited on dates after 1999, which indicates greater integrity of the genetic material recovered from individuals of 19 years of collection and onwards. Although all the fragments evaluated can be used as mini-barcode, only with one primer pair, it was possible to obtain a topology similar to that observed with the complete fragment. A large genetic variation was detected, particularly within the Bombus atratus and B. funebris species, in which a clear phylogeographic structure was revealed. Conclusions: New barcode sequences were obtained through DNA extraction and amplification protocol from museum samples. Furthermore, new information on intraspecific genetic variability was generated, detecting the presence of unique mitochondrial haplotypes that could constitute management units subject of conservation. Such information is of vital importance to formulate conservation strategies for these pollinators in Colombia.

Sobre las aves de las expediciones Santander-Bio, cuantificando el costo de colectar especímenes en Colombia / On birds of santander-bio expeditions, quantifying the cost of collecting voucher specimens in colombia

ABSTRACT Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of specimens. We present results for three expeditions conducted in Santander (municipalities of Cimitarra, El Carmen de Chucurí, and Santa Barbara), Colombia, during 2018 to collect bird voucher specimens, quantifying the costs of obtaining such material. After a sampling effort of 1290 mist net hours and occasional collection using an airgun, we collected 300 bird voucher specimens, representing 117 species from 30 families. Such collection represents one of the largest series obtained during the historical ornithological exploration of Santander. We report differences among expeditions regarding the capture rate in mist nets, as well as differences in the sizes of taxa collected by mist nets and airgun. We discuss results in the context of previous ornithological expeditions in Colombia, commenting issues on the biology of some species, particularly those considered as noteworthy records (e.g., Red-legged Tinamou [Crypturellus erythropus], Cinnamon Screech Owl [Megascopspetersoni], Saffron-headed Parrot [Pyriliapyrilia], Black Inca [Coeligena prunellei], and Chestnut-crowned Gnateater [Conopophaga castaneiceps]). We calculated that the costs of obtaining and curating a specimen in Colombia, including tissues for molecular analysis, was ~US$60.4 (~$196 176 COP), which is among published costs of obtaining voucher specimens in other taxa and countries. These costs must be considered an investment in scientific capital because voucher specimens will provide biological information for hundreds of years.

RESUMEN Hay distintas razones científicas que apoyan la recolección de aves en Colombia, un país megadiverso pero con una modesta inversión en ciencia. Pese al valor de las colecciones biológicas para el estudio riguroso de la biodiversidad, la información sobre costos monetarios de recolectar especímenes es escasa. Presentamos resultados de la cuantificación del costo de obtener especímenes de aves durante tres expediciones en Santander (municipios de Cimitarra, El Carmen de Chucurí y Santa Bárbara), Colombia, en 2018. Tras un esfuerzo de muestreo de 1290 horas/red y recolecta ocasional con una pistola de aire, obtuvimos 300 especímenes pertenecientes a 117 especies de 30 familias, una de las series más grandes de la historia de la exploración ornitológica del departamento de Santander. Reportamos diferencias entre expediciones en cuanto a la tasa de captura con redes de niebla, así como diferencias en los tamaños de los taxones recolectados mediante redes de niebla y pistola de aire. Discutimos los resultados en el contexto de otras expediciones ornitológicas en Colombia, comentando algunos aspectos de la biología de especies relevantes (e.g., Crypturellus erythropus, Megascops petersoni, Pyrilia pyrilia, Coeligena prunellei y Conopophaga castaneiceps). El costo que calculamos para obtener y curar un espécimen, incluyendo tejidos para análisis moleculares futuros, es de ~$60,4 dólares estadounidenses (~$196 176 pesos colombianos), costo que se encuentra dentro del rango para obtener especímenes de otros taxones en otros países. Estos costos deben considerarse como una inversión al capital científico, debido a que los especímenes brindarán información biológica por cientos de años.

Checklist of the false scorpions (Arachnida: Pseudoscorpiones) of Colombia, with new records and a key to the identification of the families.

Colombia is a mega-biodiverse country and rich in ecosystems as different as the Amazon and the Andes. Much is known of the vertebrate fauna, however there is still an information-gap for many arthropod groups including the arachnids. Here, we compile all the information available for pseudoscorpions (Arachnida: Pseudoscorpiones) recorded from Colombia and include several new records and distribution extensions. For each described species, we present information on taxonomic history, type localities, global and local distributions, repository of Colombian specimens, and collection numbers when available. We document 12 families, 45 genera and 65 species of pseudoscorpions for Colombia and most species belong to the families Chernetidae (27 species) and Olpiidae (8 species). We record Beierolpium venezuelense Heurtault, 1982, Geogarypus amazonicus Mahnert, 1979, Sathrochthonius venezuelanus Muchmore, 1989, and Semeiochernes armiger (Balzan, 1892) for the first time for Colombia. We further extend the known ranges of Parachernes melonopygus Beier, 1959 and Paratemnoides nidificator (Balzan, 1888). The data suggest that the Caribbean region of Colombia has the highest number of records. Total numbers are not complete and many other new pseudoscorpion species are expected.

Fungal monitoring of the indoor air of the Museo de La Plata Herbarium, Argentina.

BACKGROUND: Biological agents, such as fungal spores in the air in places where scientific collections are stored, can attack and deteriorate them. AIMS: The aim of this study was to gather information on the indoor air quality of the Herbarium of Vascular Plants of the Museo de Ciencias Naturales de La Plata, Argentina, in relation to fungal propagules and inert particles. METHODS: This study was made using a volumetric system and two complementary sampling methods: (1) a non-viable method for direct evaluation, and (2) a viable method by culture for viable fungal propagules. RESULTS: The non-viable method led to ten spore morphotypes being found from related fungal sources. A total of 4401.88spores/m3 and 32135.18 inert suspended particles/m3 were recorded. The viable method led to the finding of nine fungal taxa as viable spores that mostly belonged to anamorphic forms of Ascomycota, although the pigmented yeast Rhodotorula F.C. Harrison (Basidiomycota) was also found. A total count of 40,500fungal CFU/m3 air was estimated for all the sites sampled. CONCLUSIONS: Both the non-viable and viable sampling methods were necessary to monitor the bio-aerosol load in the La Plata Herbarium. The indoor air of this institution seems to be reasonably adequate for the conservation of vascular plants due to the low indoor/outdoor index, low concentrations of air spores, and/or lack of indicators of moisture problems.

Colombian froze biodiversity: 16 years of the tissue collection of the humboldt intiitute / La biodiversidad congelada de Colombia: 16 años de la colección de tejidos del Instituto Humboldt

Collections of frozen tissue samples stand as keystone sources of molecular information to construct biodiversity knowledge, and are particularly challenged if they focus on megadiverse countries. In 1998 the Humboldt Institute (Instituto de Investigación de Recursos Biológicos Alexander von Humboldt) began a tissue collection of Colombian biodiversity (IAvH-CT) and the aim of this work is to present a diagnostic and an historical perspective for that collection, constructed by compiling information and experiences on its management as well as by organizing and curating the information of each catalogued sample. After 16 years, the IAvH-CT harbors 16,469 samples, which represent around 2530 species from 1289 genera, and 323 families of the Colombian biodiversity. Samples are biased toward plants (44 %) and birds (40 %), but also include other animal taxa. Geographically, IAvH-CT includes samples from all Colombian departments, but there is broad variation in their coverage. When compared with other international collections, IAvH-CT fulfills several standards of sample storage and data management, but its major weakness is that several tissues seem to lack a vouchered specimen. Tissues housed at IAvH-CT have been included in at least 48 studies published in several scientific journals. IAvH-CT is implementing strategies to improve curatorial standards, fill-in taxonomic gaps, and to explore the potential of its samples to understand the outstanding Colombian biota in a cooperative research framework among institutions.

Las colecciones de tejidos son fuentes fundamentales de información molecular para el conocimiento de la biodiversidad, y son particularmente desafiantes si están enfocadas en países megadiversos. En 1998 el Instituto Humboldt (Instituto de Investigación de Recursos Biológicos Alexander von Humboldt) inició una colección de tejidos de la biodiversidad colombiana (IAvH-CT). El objetivo de este trabajo es presentar un diagnóstico y una perspectiva histórica de esta colección, mediante la compilación de información y de experiencias sobre su manejo y organizando y curando la información de cada muestra catalogada. Después de 16 años IAvH-CT resguarda 16,469 muestras, que representan alrededor de 2530 especies de 1289 géneros y 323 familias de la biodiversidad colombiana. El número de muestras está sesgado hacia plantas (44 %) y aves (40 %), pero también incluyen otros taxones animales. Geográficamente, IAvH-CT incluye muestras de todos los departamentos colombianos, pero hay una gran variación en su cobertura. Al ser comparada con otras colecciones internacionales se encuentra que IAvH-CT cumple varios estándares de almacenamiento de muestras y de manejo de datos, pero su gran debilidad es que varios tejidos aparentemente carecen de un ejemplar de referencia. Varios tejidos almacenados en IAvH-CT han sido incluidos en al menos 48 estudios publicados en varias revistas científicas. IAvH-CT está implementando estrategias para mejorar la curaduría, llenar vacíos taxonómicos y explorar el potencial de sus muestras para entender la impresionante biota colombiana en un marco de investigación en cooperación con otras instituciones.

Myxomycetes collection preserved in the herbarium of the Federal University of Roraima (Brazil) / Coleção de Myxomycetes conservada no herbário da Universidade Federal de Roraima

First records of myxomycetes in the North region of Brazil go back to the 19th century. Nevertheless, the myxobiota of this region is still largely unexplored, with only 42 species recorded, distributed in 20 genera and seven families. The objectives of this paper were to characterize the Myxomycetes collection of the Herbarium of the Federal University of Roraima (UFRR) and to add new records for the myxobiota of this State. The collection holds specimens collected in fragments of Open Ombrophilous Forest, Seasonal Semi-deciduous Forest, Riparian Forest, deforested areas and urban home gardens in the state of Roraima. The 157 exsiccates were analyzed and identified or redetermined based on identification keys, descriptions and illustrations. The collection is in good conditions of preservation and includes all subclasses of Myxomycetes, 83% of its orders, 50% of its families, and 20 species. Trichiales, with one family, three genera and six species, represents 62% of all exsiccates. Cribraria aff. splendens, Metatrichia vesparia, Physarella oblonga, Stemonaria longa and Stemonitis splendens are new records for Roraima and Arcyria obvelata, Comatricha pulchella, Stemonitis pallida and Stemonitopsis aequalis are referred for the first time in the Northern Region, enlarging the knowledge of the Brazilian geographic distribution of these species.(AU)

Os primeiros registros de mixomicetos na Região Norte do Brasil remontam ao Século XIX. Todavia, a mixobiota desta região está ainda muito pouco explorada, com apenas 42 espécies registradas, distribuídas em 20 gêneros e sete famílias. Os objetivos deste estudo foram caracterizar a coleção de Myxomycetes do Herbário da Universidade Federal de Roraima (UFRR) e adicionar novos registros para a mixobiota deste estado. A coleção contém espécimes coletados em fragmentos de Floresta Ombrófila Aberta, Floresta Estacional Semi-decidual, Mata Ciliar, áreas desmatadas e quintais urbanos no estado de Roraima. As 157 exsicatas foram analisadas e identificadas ou redeterminadas com base em chaves de identificação, descrições e ilustrações. A coleção encontra-se em boas condições de conservação e inclui todas as subclasses de Myxomycetes, 83% das ordens, 50% das famílias e 20 espécies. A ordem Trichiales, com uma família, três gêneros e seis espécies, corresponde a 62% das exsicatas. Cribraria aff. splendens, Metatrichia vesparia, Physarella oblonga, Stemonaria longa e Stemonitis splendens são novos registros para o estado de Roraima e Arcyria obvelata, Comatricha pulchella, Stemonitis pallida e Stemonitopsis aequalis são referidas pela primeira vez para a Região Norte, ampliando a distribuição geográfica conhecida para estas espécies no Brasil.(AU)
