Phylogenetic relationships of the Mangrove Hummingbird, "Amazilia" boucardi (Apodiformes: Trochilidae) of Costa Rica / Relaciones filogenéticas del Colibrí manglero "Amazilia" boucardi (Apodiformes: Trochilidae) de Costa Rica

Abstract Introduction: A recent revision of the generic classification of the Trochilidae based on DNA sequences revealed many inconsistencies with the current generic classification, largely based on plumage characters subject to homoplasy, especially in the Trochilini, the largest tribe. A thorough generic reorganization brought the classification into accord with the phylogeny, but due to lack of genetic data, two species remained unclassified. One of these was the Mangrove Hummingbird, "Amazilia" boucardi, endemic to Costa Rica and included in the IUCN red list of threatened species. Objective: To obtain molecular evidence to clarify the generic relationships of "A." boucardi. Methods: We isolated DNA from tissues of this species and amplified 4 nuclear and 4 mitochondrial fragments and compared these with homologous fragments from 56 species in the Trochilini, constructing phylogenetic trees with maximum likelihood and Bayesian methods. Results: Our phylogenetic analyses confirmed the placement of boucardi in the Trochilini and definitely excluded it from Amazilia but placed it with high confidence in the genus Chrysuronia Bonaparte, 1850, within which its closest relative is C. coeruleogularis, which also inhabits mangroves. Conclusions: Our genetic data based on nuclear and mitochondrial regions clearly indicate the relationship of A. boucardi and L. coeruleogularis. Moreover, it is also supported by their habitat distribution in the mangroves of the Pacific coast of Costa Rica and Western Panama. Therefore, we suggested to exclude A. boucardi as "incertae sedis".

Resumen Introducción: Una revisión reciente de la clasificación de la familia Trochilidae con base en secuencias de ADN demostró muchas incongruencias con la clasificación genérica previa, que había sido hecho con base en caracteres del plumaje muy sujetos a homoplasia, especialmente en la tribu más grande, Trochillini. Una reorganización de los géneros logró llevar su clasificación genérica a la concordancia con la filogenia, pero debido a la ausencia de datos genéticos, dos especies permanecieron sin clasificar. Una de estas fue el colibrí de manglar Amazilia boucardi, una especie endémica de Costa Rica, considerada como amenazada en la lista roja de la UICN. Objetivo: Obtener evidencia molecular para esclarecer las relaciones genéricas de A. boucardi. Métodos: Se aisló ADN de tejidos de esta especie y se amplificaron 4 fragmentos de ADN del núcleo y 5 de la mitocondria, y se compararon con fragmentos homólogos de 56 especies en la tribu Trochillini, generando árboles filogenéticos con métodos de máxima verosimilitud y bayesiano. Resultados: Los análisis filogénticos obtenidos confirmaron la ubicación de boucardi en Trochilini y definitivamente la excluyó del género Amazilia, pero la ubicó con un alto grado de confianza en el género Chrysuronia Bonaparte, 1850, dentro los cuales su pariente más cercano es C. coeruleogularis, que también habita manglares. Conclusiones: Nuestros datos genéticos basados en regiones nucleares y mitocondriales indican claramente la relación entre A. boucardi and L. coeruleogularis. Es más, lo anterior se sustenta por su distribución en los manglares de la costa Pacífica de Costa Rica y oeste de Panamá. Por lo tanto, sugerimos excluir a A. boucardi como "incertae sedis".

Actualización en taxonomía, diagnóstico y tratamiento de las dermatofitosis / Update on taxonomy, diagnosis and treatment

Los dermatofitos son un grupo de hongos responsables de las dermatofitosis o tiñas, pudiendo afectar piel, uñas y pelo. En la actualidad están constituidos por los géneros Epidermophyton, Trichophyton, Microsporum, Arthroderma, Paraphyton, Lophophyton y Nannizzia. El examen microscópico directo y el cultivo en agar siguen siendo el estándar de oro para la identificación, sin embargo, en ocasiones se requiere de la biología molecular para poder corroborar una determinada especie. Dependiendo de la localización, del número de lesiones y de la extensión, el tratamiento de las dermatofitosis puede ser tópico o sistémico. Trichophyton indotineae y T tonsurans pueden expresar resistencia a la terbinafina y azoles, respectivamente.

Dermatophytes are a group of fungi responsible for dermatophytosis or ringworm, which can affect the skin, nails and hair. Currently, they are assembled by the genera Epidermophyton, Trichophyton, Microsporum, Arthroderma, Paraphyton, Lophophyton and Nannizzia. Direct microscopic examination and culture on agar remain the gold standard for identification, however, molecular biology is sometimes required to confirm a certain species. Depending on the location, the number of lesions and the extension, the treatment of dermatophytosis can be topical or systemic. Trichophyton indotineae and T tonsurans can express resistance to terbinafine and azoles, respectively.

Evaluating the reliability of DNA Barcoding for Central American Pacific shallow water echinoderms identification: a molecular taxonomy and database accuracy analysis / Evaluando la fiabilidad del Código de Barras de ADN para la identificación de equinodermos en aguas poco profundas del Pacífico de América Central: un análisis de taxonomía molecular y precisión de bases de datos

Abstract Introduction: Molecular divergence thresholds have been proposed to distinguish recently separated evolutive units, often displaying more accurate putative species assignments in taxonomic research compared to traditional morphological approaches. This makes DNA barcoding an attractive identification tool for a variety of marine invertebrates, especially for cryptic species complexes. Although GenBank and the Barcode of Life Data System (BOLD) are the major sequence repositories worldwide, very few have tested their performance in the identification of echinoderm sequences. Objective: We use COI echinoderm sequences from local samples and the molecular identification platforms from GenBank and BOLD, in order to test their accuracy and reliability in the DNA barcoding identification for Central American shallow water echinoderms, at genus and species level. Methods: We conducted sampling, tissue extraction, COI amplification, sequencing, and taxonomic identification for 475 specimens. The 348 obtained sequences were individually enquired with BLAST in GenBank as well as using the Identification System (IDS) in BOLD. Query sequences were classified depending on the best match result. McNemar's chi-squared, Kruskal-Wallis's and Mann-Whitney's U tests were performed to prove differences between the results from both databases. Additionally, we recorded an updated list of species reported for the shallow waters of the Central American Pacific. Results: We found 324 echinoderm species reported for Central American Pacific shallow waters. Only 118 and 110 were present in GenBank and BOLD databases respectively. We proposed 325 solved morphology-based identities and 21 provisional identifications in 50 putative taxa. GenBank retrieved 348 molecular-based identifications in 58 species, including twelve provisional identifications in tree taxa. BOLD recovered 170 COI identifications in 23 species with one provisional identification. Nevertheless, 178 sequences retrieved unmatched terms (in 34 morphology-based taxa). Only 86 sequences (25 %) were retrieved as correct identifications and 128 (37 %) as identification errors in both platforms. We include 84 sequences for eleven species not represented in GenBank and 65 sequences for ten species in BOLD Echinoderm COI databases. The identification accuracy using BLAST (175 correct and 152 incorrect identifications) was greater than with IDS engine (110 correct and 218 identification errors), therefore GenBank outperforms BOLD (Kruskal-Wallis = 41.625, df = 1, p < 0.001). Conclusions: Additional echinoderm sample references are needed to improve the utility of the evaluated DNA barcoding identification tools. Identification discordances in both databases may obey specific parameters used in each search algorithm engine and the available sequences. We recommend the use of barcoding as a complementary identification source for Central American Pacific shallow water echinoderm species.

Resumen Introducción: Se han propuesto los umbrales de divergencia molecular para distinguir unidades evolutivas recientemente separadas, que a menudo muestran asignaciones de especies putativas más precisas en la investigación taxonómica en comparación con los enfoques morfológicos tradicionales. Esto hace que los Códigos de Barras de ADN sean una herramienta de identificación atractiva para una variedad de invertebrados marinos, especialmente para complejos de especies crípticas. Aunque GenBank y Barcode of Life Data System (BOLD) son los principales repositorios de secuencias en todo el mundo, muy pocos han probado su desempeño en la identificación de secuencias de equinodermos. Objetivo: Utilizamos secuencias de equinodermos COI de muestras locales y las plataformas de identificación molecular de GenBank y BOLD, para probar su precisión y confiabilidad en la implementación de códigos de barras de ADN para equinodermos de aguas someras de Centroamérica, a nivel de género y especie. Métodos: Realizamos muestreo, extracción de tejido, amplificación de COI, secuenciación e identificación taxonómica de 475 especímenes. Las 348 secuencias obtenidas fueron consultadas individualmente con BLAST en GenBank así como utilizando el Sistema de Identificación (IDS) en BOLD. Las secuencias consultadas se clasificaron según el mejor resultado de coincidencia. Se realizaron las pruebas chi-cuadrado de McNemar, Kruskal-Wallis y U de Mann-Whitney para comprobar diferencias entre los resultados de ambas bases de datos. Además, registramos una lista actualizada de especies reportadas para las aguas someras del Pacífico Centroamericano. Resultados: Encontramos 324 especies de equinodermos reportadas para aguas someras (< 200 m) del Pacífico centroamericano. Sólo 118 y 110 estaban presentes en las bases de datos GenBank y BOLD respectivamente. Propusimos 325 identidades resueltas basadas en morfología y 21 identificaciones provisionales en 50 taxones putativos. GenBank recuperó 348 identificaciones de base molecular en 58 especies, incluidas doce identificaciones provisionales en tres taxones. BOLD recuperó 170 identificaciones de COI en 23 especies con una identificación provisional. Sin embargo, 178 secuencias recuperaron términos no coincidentes (en 34 taxones basados en morfología). Sólo 86 secuencias (25 %) se recuperaron como identificaciones correctas y 128 (37 %) como errores de identificación en ambas plataformas. Incluimos 84 secuencias para once especies no representadas en GenBank y 65 secuencias para diez especies ausentes en las bases de datos BOLD Echinoderm COI. La precisión de la identificación usando BLAST (175 identificaciones correctas y 152 incorrectas) fue mayor que con el motor IDS (110 correctas y 218 errores de identificación), por lo tanto, GenBank supera a BOLD (Kruskal-Wallis = 41.625, df = 1, p < 0.001). Conclusiones: Se necesitan muestras adicionales de equinodermos de referencia para mejorar la utilidad de las herramientas de identificación de códigos de barras de ADN evaluadas. Las discordancias de identificación en ambas bases de datos pueden obedecer a parámetros específicos utilizados en cada algoritmo de búsqueda y a las secuencias disponibles. Recomendamos el uso de códigos de barras como fuente de identificación complementaria para las especies de equinodermos de aguas someras del Pacífico centroamericano.

Eighty-five years awaiting for description: a new species of Tabanus Linnaeus (Diptera: Tabanidae) from the Paraná State, in Brazil

ABSTRACT The largest genus within the family Tabanidae (Diptera: Brachycera), Tabanus Linnaeus, has a worldwide distribution and includes medium to large conspicuous flies. Although the species are difficult to identify and a large number have already been described, several new Neotropical species have been reported for science in the past few years. Taxonomy, the science that describes and catalogs biodiversity, depends on collections, as these preserve specimens for later purposes, allowing examination and checking by specialists. In this paper we describe a new species, Tabanus argentistrigatus sp. n. based on two specimens stored in the collection of the Museum of Zoology of the São Paulo University since 1938. The new species is only known from one location in the state of Paraná, which is now highly anthropized.

A new species of the sharpshooter genus Balacha from an alpine field in southeastern Brazil (Insecta: Hemiptera: Cicadellidae: Cicadellini)

ABSTRACT The sharpshooter genus Balacha Melichar, 1926 includes nine species and is distributed in southeastern and southern Brazil, Uruguay, Paraguay, and Argentina. All species of Balacha use only members of the genus Eryngium (Apiaceae) as host plants, except for a recently described species that is associated with Actinocephalus polyanthus (Eriocaulaceae). Here we describe and illustrate an additional species, B. caledonia sp. nov., from an alpine field in Nova Friburgo, state of Rio de Janeiro, southeastern Brazil, which is also associated with Eryngium. Among the known species of the genus, the new taxon is morphologically most similar to B. caparao Takiya & Mejdalani, 2004, but can be easily distinguished by the shaft of the aedeagus, which has a dorsal lobe on the basal half and no ventroapical lobe, and the female sternite VII with the borders of the posterior emargination sinuous. Our studies indicate that the type locality of the new species and its surrounding Atlantic Forest area in Nova Friburgo harbor an interesting and diverse but still poorly known sharpshooter fauna, including the recently discovered Paratubana auromarginata Côrte et al., 2021 (also from Eryngium) and Cavichiana caelivittata Mejdalani et al., 2023 (from bromeliads).

Leptogenys pujoli, a new amazonian species, and the redescription of Leptogenys famelica Emery, 1896 (Formicidae: Ponerinae)

ABSTRACT We provide an update on the famelica species group, redescribing Leptogenys famelica Emery, 1896 and describing a new species, Leptogenys pujoli n. sp., based on worker specimens. The new species is smaller than L. famelica and can be distinguished by the indistinct mesometanotal suture, and the petiolar node with an anterodorsal margin mostly straight anterior to spiracle in lateral view. Leptogenys famelica is distributed from Costa Rica to Panama, while L. pujoli n. sp. is distributed throughout the Brazilian Amazon, from French Guiana to Bolivia. Some records previously attributed to L. famelica remain uncertain, potentially being either L. famelica or L. pujoli n. sp., or perhaps representing one or more undescribed species. We update the key to Leptogenys workers by Lattke (2011) and include images. We synthesize available knowledge about the possible biology of these species and propose that both L. famelica and L. pujoli n. sp. are generalist predators and that their reproduction is dependent on gamergates.

New occurrences of mosquitoes (Diptera: Culicidae) in the Atlantic Forest biome of the Brazilian Northeast

ABSTRACT Background: Information regarding the distribution of Culicidae species in the northeastern region of Brazil is scarce. Methods: Immatures were collected from approximately four fragments of the Atlantic Forest. Results: This study presents new occurrences of 18 Culicidae species in Pernambuco state: Anopheles kompi, Georgecraigius fluviatilis, Culex bidens, Culex chidesteri, Culex bastagarius, Culex imitator, Mansonia humeralis, Wyeomyia incaudata, Uranotaenia apicalis, Culex mollis, Culex usquatus, Culex dunni, Culex serratimarge, Culex ybarmis, Culex microphyllus, Sabethes purpureus, Wyeomyia pilicauda, and Wyeomyia airosai. The last nine species were also new records for the northeast region. Conclusions: With the inclusion of these newly recorded species, the total number of mosquitoes documented in Pernambuco state now rises to 94.

New records of Coronatella (Crustacea, Branchiopoda, Chydoridae) from Colombia with the first report of Coronatella undata and of the male of Coronatella monacantha

Abstract Biological samples obtained from a small temporary pond of northern Colombia yielded the first record Coronatella undata Sousa, Elmoor-Loureiro and Santos, 2015 and of the male of C. monacantha (Sars, 1901) for Colombia. In this study, the morphology of female of Coronatella undata and female and male of C. monacantha was described and compared to other species within the genus. C. undata was originally described from Brazil and, among the species of the Coronatella monacantha complex, seems to be closely related to C. acuticostata (Sars, 1903). C. undata shows some similarities with C. monacantha, but it can be identified by important diagnostic characters such as: 1) posterior-ventral corner of valve with two denticles, 2) seta on exopodite of trunk limb II rudimentary, 3) filter comb of trunk limb II with six setae, 4) ODL seta of trunk limb I shorter than longest seta of IDL. C. monacantha is the most reported species in the Neotropical region and the male most resemble C. paulinae Sousa, Elmoor-Loureiro & Santos, 2015 in relation to (i), length/wide of postabdomen ratio (ii) basal spine almost straight and (iii)) long basal spine reaching the mid-length of basal spine. However, they can be separated by (i) number of lateral seta on the antennule, (ii) postanal angle, (iii) position of gonopore (iv) presence of a denticle on posterior-ventral corner of valve

Resumo Amostras biológicas obtidas de uma pequena lagoa temporária do norte da Colômbia proporcionaram o primeiro registro de Coronatella undata Sousa, Elmoor-Loureiro e Santos, 2015 e do macho de Coronatella monacantha (Sars, 1901) na Colômbia. Neste estudo, foi descrita a morfologia de fêmeas de C. undata e de fêmeas e machos de C. monacantha, comparando-a com outras espécies do gênero. Coronatella undata foi descrita originalmente no Brasil e, entre as espécies do complexo C. monacantha, parece estar intimamente relacionada com Coronatella acuticostata (Sars, 1903). Coronatella undata apresenta algumas semelhanças com C. monacantha, mas pode ser identificada por seus principais caracteres, tais como: 1) ângulo posterior ventral da valva com dois dentículos; 2) cerda rudimentar no exopodito do ramo do tronco II; 3) filtro da gnatobase do apêndice torácico II com seis cerdas; 4) cerda ODL do membro do tronco I mais curta que a cerda mais longa do IDL. Coronatella monacantha é a espécie mais relatada na região neotropical, e o macho se assemelha mais a Coronatella paulinae Sousa, Elmoor-Loureiro & Santos em relação à/ao: (i) razão comprimento / largura do pós-abdômen, (ii) espinho basal quase reto e (iii) espinho basal longo com a metade do comprimento do espinho basal. No entanto, eles podem ser separados pelo/pela: (i) número de cerdas laterais na antênula, (ii) ângulo postanal, (iii) posição do gonóporo e (iv) presença de dentículo no canto ventral posterior da valva.

Nuevos nombres para antiguas especies fúngicas de importancia médica / New names for ancient fungal species of medical importance

En las últimas décadas ha existido un reordenamiento de los géneros y especies fúngicas de importancia médica debido a los constantes avances en la biología molecular. Desde la declaración de Amsterdam en el año 2011, se han ido abandonando la taxonomía de dos nombres (sexual y asexual) por cada especie, además se ha priorizado al primer nombre descrito. Dado que se recomienda comenzar a utilizar los nombres actualizados de los géneros y especies de levaduras y hongos filamentosos, se propone una transición utilizando el nombre actual, y el antiguo entre paréntesis escrito con minúscula, con el fin de evitar confusiones en los médicos clínicos ya acostumbrados a la nomenclatura previa.

In recent decades there has been a rearrangement of fungal genera and species of medical importance due to constant advances in molecular biology. Since the Amsterdam declaration in 2011, the taxonomy of two names (sexual and asexual) for each species has been abandoned, and the first name described has also been prioritized. Since it is recommended to start using the updated names of the genera and species of yeasts and filamentous fungi, a transition is proposed using the current name, and the old one in parentheses written with lower case, in order to avoid confusion in clinician physicians already accustomed to the previous nomenclature.

Notes on Anqasha picta (Pocock, 1903) and description of a new species of Anqasha from Peru (Araneae, Theraphosidae, Theraphosinae)

The monotypic Peruvian genus Anqasha with type species Anqasha picta (Pocock 1903) is revised. A female of A. picta from the type locality of Caraz is herein described for the first time. The recently described females of A. picta coming from Recuay are transferred to the new taxon, which is herein described, diagnosed, and illustrated. Males of A. minaperinensis sp. nov. differ from that of A. picta in the shape of retrolateral branch of subapical apophyses on male tibia I, which is apically flattened and having three short spines. Females of A. minaperinensis sp. nov. differ from A. picta in the shape of seminal receptacles.

Se revisa el género monotípico peruano Anqasha, con la espécie tipo Anqasha picta (Pocock 1903). Se describe por primera vez una hembra de A. picta de la localidad de tipo en Caraz. Las hembras recientemente descritas de A. picta procedentes de Recuay son transferidas al nuevo taxon, el cual se describe, diagnostica e illustra aquí. Los machos de A. minaperinensis sp. nov. se differencían de A. picta en la forma de la rama retrolateral de la apófísis subapical en la tibia I del macho, la cual está aplanada apicalmente y llevando tres espinas cortas. Las hembras de A. minaperinensis sp. nov. se differencían de A. picta en la forma de los receptaculos seminales.

New pseudoscorpion species (Pseudoscorpiones: Hesperolpiidae) from Lima City, Peru

This study describes and illustrates a new species of arachnid, the pseudoscorpion Stenolpium sayrii sp. nov., collected at Pucllana, an archaeological site in the city of Lima, Peru. With this description, the total number of known Stenolpium species worldwide reaches eight, and in Peru specifically, it increases to seven. The discovery of this new species in Peru's most populous city serves as an exemplar highlighting the extensive scope for further research on Peruvian fauna in general, particularly on its arachnids.

En este trabajo, una nueva especie de arácnido, el pseudoscorpión Stenolpium sayrii sp. nov., colectada en Pucllana, sitio arqueológico de la ciudad de Lima, Perú, es descrita e ilustrada. Con esta descripción, el número de especies conocidas de Stenolpium en el mundo asciende a ocho en total y para el Perú a siete. El descubrimiento de esta nueva especie en la ciudad más poblada del Perú es un ejemplo de lo mucho que falta investigar sobre la fauna peruana en general y sobre sus arácnidos en particular.

Estatus taxonómico de Talides basistrigata Eaton, 1932 (Lepidoptera, Hesperiidae) y su reincorporación basados en una evaluación integrativa

Talides basistrigata Eaton, 1932, originalmente descrita de Perú, posteriormente fue transferida por Evans (1955) al género Hylephila Billberg, 1820, y considerada como una subespecie de H. phyleus (Drury, 1773), argumentando que basistrigata ocurre en ambientes más secos que los que habita phyleus. Actualmente se mantiene el rango taxonómico propuesto por Evans. El objetivo del presente trabajo es restituir el estatus taxonómico de especie válida para basistrigata con base en un análisis integrativo considerando aspectos morfológicos, ecológicos y genéticos. Se examinó las estructuras genitálicas en ejemplares de basistrigata y phyleus, se obtuvo secuencias del gen mitocondrial COI para ambas especies y se recopiló datos en campo para conocer su comportamiento de oviposición en los alrededores de Arequipa, suroeste de Perú. Como resultado del examen morfológico se halló diferencias notorias entre las estructuras genitálicas de ambas especies, principalmente en los procesos caudales de las valvas, la disposición de las pectinas y la forma del uncus en los machos. Con relación al análisis genético, se halló una distancia genética mayor a 3% entre ambas especies, apoyando así el estatus taxonómico de especie para basistrigata. Adicionalmente, desde una perspectiva ecológica, se registró que ambas especies utilizan distintos mecanismos de oviposición y diferentes plantas hospederas, exhibiendo además simpatría espacial y sincronía temporal en la vertiente occidental de los Andes en Perú. Se redescribe el macho y hembra adultos de basistrigata y se designa su lectotipo.

Talides basistrigata Eaton, 1932, originally described from Peru, was subsequently transferred to the genus Hylephila Billberg, 1820 by Evans (1955) and considered a subspecies of H. phyleus (Drury, 1773), arguing that basistrigata inhabits drier environments than phyleus. Currently, the taxonomic status proposed by Evans is retained. The aim of this study is to reinstate the taxonomic status of valid species for basistrigata based on an integrative analysis considering morphological, ecological, and genetic aspects. Genitalic structures were examined in specimens of both basistrigata and phyleus, mitochondrial COI gene sequences were obtained for both species, and field data were collected to understand their oviposition behaviour in the vicinity of Arequipa city, southwestern Peru. As a result of the morphological examination, notable differences were found between the male genitalia structures of both species, primarily in the caudal processes of the valvae, the arrangement of the pectines, and the shape of the uncus. Regarding the genetic analysis, a genetic distance of greater than 3% was observed between the two species, thus supporting the taxonomic status of species for basistrigata. Additionally, from an ecological perspective, it was recorded that both species employ distinct oviposition mechanisms and different host plants, exhibiting spatial sympatry and temporal synchrony on the western slope of the Andes in Peru.

Contribution to the knowledge of cladocerans fauna (Crustacea, Branchiopoda) from La Española lagoon, Colombia

Thirty-five cladocerans species are recorded from La Española lagoon in the Orinoquia region of Colombia; all are new records for Meta Department and 10 for Colombia. With the addition of these new reports, the total number of cladocerans for Colombia and the Meta department is increased by 124 and 38 species, respectively. The cladoceran fauna from the surveyed area is represented mainly by widespread species, commonly found in the Neotropical regions, but local morphological data are scarce in the regional literature. Brief diagnostic description of 18 species of cladoceran fauna recorded of the Meta department-Colombia are provided together with illustrations of taxonomically significant appendages, morphological remarks, notes on the variability of some species, and their distribution.

Se registran treinta y cinco especies de cladóceros de la laguna La Española en la región de la Orinoquia de Colombia; todos ellos son nuevos registros para el Departamento del Meta y 10 para Colombia. Con la incorporación de estos nuevos reportes, el número total de cladóceros para Colombia y el departamento del Meta se incrementa en 124 y 38 especies respectivamente. La fauna de cladóceros del área estudiada está representada principalmente por especies de amplia distribución y que se encuentran comúnmente en las regiones Neotropicales, pero los datos morfológicos locales son escasos en la literatura regional. Se proporcionan breves descripciones diagnosticas de 18 especies registradas para la fauna de cladóceros del departamento del Meta-Colombia, junto con ilustraciones de apéndices taxonómicamente significativos, comentarios morfológicos, notas sobre la variabilidad de algunas especies y su distribución.

Una nueva especie de Chrysochlamys (Clusiaceae, Clusioideae, Clusieae) del Parque Nacional Cordillera Azul, Loreto, Perú

Se describe e ilustra Chrysochlamys montieliae, nueva especie de la familia Clusiaceae, subfamilia Clusioideae, tribu Clusieae, procedente del Parque Nacional Cordillera Azul, del Departamento de Loreto. Siguiendo los criterios de la UICN, proponemos categorizarla como Datos Insuficientes (DD), debido a que solo es conocida de la localidad tipo. Igualmente, se discute sus relaciones con las especies afines.

Chrysochlamys montieliae, a new species of the Clusiaceae family, Clusioideae subfamily, Clusieae tribe, from the Cordillera Azul National Park, Department of Loreto, is described and illustrated. Following the IUCN criteria, we propose to categorize it as Data Deficient (DD), since it is only known from the type locality. In addition, their relationships with related species are discussed.

Nueva especie del género Charinus (Amblypygi; Charinidae) del Cusco, Perú

Se describe una especie nueva del género Charinus Simon, 1892, procedente del distrito Santa Teresa (1436 -1511 m de altitud), en La Convención, Cusco, Perú, la cual es la tercera para dicha región y la quinta para este país sudamericano. Su aspecto general y los gonópodos de la hembra son muy parecidos a los de Charinus longitarsus Armas & Palomino-Cardenas, 2016 y C. yanatile Palomino-Cardenas & Armas, 2022, también del Cusco; pero se diferencia de ambas por presentar en la distitibia del cuarto par de patas 16 tricobotrios, en lugar de 14; además, C. longitarsus posee 30 tarsómeros en las patas I (43 en la especie nueva); mientras que en C. yanatile, el tubérculo ocular es más grande y el tarsómero 1 del primer par de patas es más largo que los dos siguientes juntos (en la especie nueva es más corto). También se enmienda la descripción de los gonópodos femeninos de C. longitarsus y se incluye una clave taxonómica para la identificación de las especies peruanas de Charinus.

A new species of the genus Charinus Simon, 1892 is described from Santa Teresa District (1436 -1511 m of altitude), La Convención, Cusco, Peru, being this the third Charinus species from this region and the fifth one for this South American country. Its general feature and female gonopods greatly resembles Charinus longitarsus Armas & Palomino-Cardenas, 2016, and C. yanatile Palomino-Cardenas & Armas, 2022, from Cusco, too; but it differs from them by having 16 instead of 14 trichobothria in the distitibia of leg IV; on the other hand, in C. longitarsus the leg I has 30 tarsomeres (43 in the new species); whereas C. yanatiles has larger median ocular tubercle and the first tarsomere of leg I is longer than tarsomeres 1+2 joined. Also, the description of the female gonopods of C. longitarsus is emended and a taxonomic key for the identification of the Peruvian species of Charinus is given.
