Anfibios y reptiles del departamento de Ica con comentarios sobre su distribución

En este trabajo se presenta el listado actualizado de anfibios y reptiles de Ica. Las especies son comentadas, acompañadas de mapas de distribución y claves de identificación para reptiles y anfibios. Se recopiló información de registros en colecciones científicas, artículos científicos, informes de agencias gubernamentales de vida silvestre y bases de datos taxonómicas especializadas. Adicionalmente, entre los años 2019 y 2020 se realizaron evaluaciones de campo en zonas con vacíos de información. Se encontraron un total de 22 especies (anfibios 3 y reptiles 19). Los nuevos registros de reptiles para Ica incluyen la lagartija Liolaemus evaristoi y la serpiente Incaspis tachymenoides en la provincia de Chincha a 4200 y 3200 m de altitud respectivamente, la lagartija Stenocercus ornatissimus y la serpiente ciega Epictia tesselata en la provincia de Pisco a 3500 y 2800 m respectivamente. Los nuevos registros de anfibios incluyen a Pleurodema marmoratum en la provincia de Chincha (3900 m) y Telmatobius rimac en las provincias de Chincha y Palpa a 3900 y 2350 m respectivamente. La mayor riqueza y endemismos locales se encontraron en el desierto costero, mientras que, las ampliaciones de distribución y endemismos regionales se registraron en la vertiente occidental de los Andes. También, se observa que las familias Leptotyphlopidae y Viperidae, y los géneros Dicrodon, Stenocercus y Oxyrophus terminan su distribución en la vertiente occidental y la zona costera de los departamentos de Ica y Arequipa sin representantes en el extremo sur del Perú y Chile.

This paper presents the updated list of amphibians and reptiles of Ica. Species are commented, accompanied by distribution maps and identification keys for reptiles and amphibians. Information was collected from scientific collections, scientific articles, governmental wildlife agency reports, and specialized taxonomic database. Additionally, between 2019 and 2020, field surveys were carried out in areas with information gaps. A total of 22 species were found (amphibians 3 and reptiles 19). The new records of reptiles include the Liolaemus evaristoi lizard and the Incaspis tachymenoides snake from Chincha province at 4200 and 3200 m altitude respectively, the Stenocercus ornatissimus lizard and the blind snake Epictia tesselata from Pisco province at 3500 and 2800 m respectively. New amphibian records include Pleurodema marmoratum in Chincha province (3900 m) and Telmatobius rimac in Chincha and Palpa provinces at 3900 and 2350 m respectively. The greatest richness and local endemism were found in the coastal desert, while the expansion of distribution and regional endemism were recorded on the western slope of the Andes. Also, it is observed that the families Leptotyphlopidae and Viperidae, and the genera Dicrodon, Stenocercus and Oxyrophus are finishing their distribution in the western slope and the coastal zone of the departments of Ica and Arequipa without representatives in the extreme south of Peru and Chile.

Treehoppers (Hemiptera, Auchenorrhyncha: Aetalionidae and Membracidae) from western Acre, Brazil, with emphasis on the fauna of Serra do Divisor National Park / Soldadinhos (Hemiptera, Auchenorrhyncha: Aetalionidae e Membracidae) do extremo oeste do Acre, Brasil, com ênfase na fauna do Parque Nacional Serra do Divisor

Abstract The first list of Aetalionidae and Membracidae species for western Acre is presented, including the Alto do Juruá regions of Serra do Divisor National Park and the Campus Floresta of the Federal University of Acre. In total, 94 species of treehoppers were collected, of which Centrotinae (Membracidae) is recorded for the first time for Brazil (Abelus maculatus Schimidt), another 16 species are new Brazilian records, and 69 species (Aetalionidae and Membracidae) are new records for Acre. Data on type locality, geographic distribution and images of all species are presented. The males of Lophyraspis fenestrata Sakakibara & Creão-Duarte and Erechtia sanguinolenta (Fairmaire) are known for the first time. The species diversity was compared to four other treehopper surveys in the Amazon region, with similarity indices of about 43.6% for Colombian Amazon (at least 650 km away), 27.6% for Panguana Biological Research Station, Peru (250 km), 20.2% for Adolpho Ducke Forest Reserve, Brazil (1,600 km) and 8.5% for Villa Carmen Biological Station/Los Amigos Biological Station, Peru (600/700 km). The estimated richness of Serra do Divisor National Park was just over 70%, suggesting that local diversity could be significantly higher than that presented in this study.

Resumo A primeira lista de espécies de Aetalionidae e Membracidae para o extremo oeste do Acre é apresentada, incluindo as regiões do Alto do Juruá do Parque Nacional da Serra do Divisor e o Campus Floresta da Universidade Federal do Acre. No total, foram coletadas 94 espécies de soldadinhos, das quais Centrotinae (Membracidae) é registrada pela primeira vez para o Brasil (Abelus maculatus Schimidt), 16 outras espécies de membracídeos são novos registros para o Brasil e 69 espécies (Aetalionidae e Membracidae) são novos registros para o Acre. Dados sobre localidade-tipo, distribuição geográfica e imagens de todas as espécies são apresentados. Os machos de Lophyraspis fenestrata Sakakibara & Creão-Duarte e Erechtia sanguinolenta (Fairmaire) são conhecidos pela primeira vez. A diversidade de espécies foi comparada a outros quatro levantamentos de soldadinhos na região amazônica, com índices de similaridade de cerca de 43,6% para a Amazônia colombiana (pelo menos 650 km de distância), 27,6% para a Estação de Pesquisa Biológica de Panguana, Peru (250 km), 20,2% para Adolpho Reserva Florestal Ducke, Brasil (1.600 km) e 8,5% para Estação Biológica Villa Carmen/Estação Biológica Los Amigos, Peru (600/700 km). A riqueza estimada do Parque Nacional da Serra do Divisor foi de pouco mais de 70%, sugerindo que a diversidade local pode ser significativamente maior do que a apresentada neste estudo.

Croton L. (Crotonoideae, Euphorbiaceae) in a protected area in Northeast Brazil / Croton L. (Crotonoideae, Euphorbiaceae) em uma área protegida do Nordeste do Brasil

Abstract Croton is the largest genus of Crotonoideae Burmeist. (ca. 1200 species), with approximately 300 species distributed in all the phytogeographic domains in Brazil. The Chapada of Araripe Environmental Protection Area (CA-EPA) is one of the largest protected areas in northeastern Brazil and comprises many different types of vegetation. Considering the expressive representation of Croton in that northeastern region and its morphological complexity, we carried out a taxonomic study of the species occurring in the CA-EPA. The analysis of collections deposited in regional herbaria, together with field observations, revealed 18 Croton species, five of which had never been cited as occurring in the study area; seven of those taxa are endemic to the Brazilian semiarid region. Croton species were recorded in all of the vegetation types in the CA-EPA, especially in the "carrasco" and "caatinga" vegetation. The plants habits, the shapes of their stipules, extrafloral nectaries, indumenta, and staminate and pistillate sepals were important characteristics for their differentiation.

Resumo Croton é o maior gênero de Crotonoideae Burmeist. (ca. 1200 espécies), com aproximadamente 300 espécies distribuídas em todos os domínios fitogeográficos brasileiros. A Área de Proteção Ambiental da Chapada do Araripe (APA-CA) é uma das maiores áreas protegidas do nordeste brasileiro e compreende diversos tipos de vegetação. Considerando a expressiva representatividade de Croton no Nordeste, bem como sua complexidade morfológica, realizamos um estudo taxonômico das espécies ocorrentes na APA-CA. A análise de coleções depositadas em herbários regionais, juntamente com observações de campo, revelou 18 espécies de Croton, cinco das quais nunca haviam sido citadas como ocorrendo na área de estudo; sete desses táxons são endêmicos do semiárido brasileiro. As espécies foram registradas em todas as fitofisionomias da APA-CA, principalmente na vegetação de carrasco e caatinga. Os hábitos das plantas, as formas de suas estípulas, nectários extraflorais, indumentos e sépalas estaminadas e pistiladas foram características importantes à diferenciação.

Hidden in the dung: first record of Maculantrops hirtipes () (Diptera, Sphaeroceridae) from Brazil / Escondido no esterco: primeiro registro de Maculantrops hirtipes () (Diptera, Sphaeroceridae) do Brasil

Abstract We recorded for the first time the lesser dung fly Maculantrops hirtipes (Macquart, 1844) from Brazil, state of Rio Grande do Sul. Twenty-five specimens were reared from the dung of Myocastor coypus (Molina, 1782), this is the first record of the feeding substrate for the genus Maculantrops and the second only for the Archiborborinae. In addition, we describe the puparium, provide an updated distribution map and additional photographs of the species.

Echinoderms (Echinodermata) from the Central Mexican Pacific

Introduction: The echinoderms from the Central Mexican Pacific are of high scientific interest and, prior to this present work, there was a lack of basic information that included incomplete checklists with inconsistencies in systematics and spatial distribution. Objective: To provide a historical review, and an updated checklist with a more complete richness of echinoderms for each state and island of the region. Methods: A checklist was elaborated based on an exhaustive literature search of the Echinodermata, and was complemented with taxonomical revisions of Ophiuroidea scientific collections. All the geographical coordinates of the records were validated. Results: The region harbors 187 species of Echinodermata: three Crinoidea, 35 Asteroidea, 67 Ophiuroidea, 32 Echinoidea, and 50 Holothuroidea. We detected 52 records in the literature that must be considered as invalid and five as doubtful. We provide 16 new records of Ophiuroidea from different states and islands; of them, four are new records for the region. Jalisco presented the highest number of species (84), followed by the coast of Nayarit (74), Michoacán (63), and Colima (55); among the islands, Revillagigedo showed the major number of species (85) followed by Marías (81), Marietas (48), and Isabel (44). Conclusions: The numbers of species known in the region are mostly related to both sampling effort and environmental characteristics that promote high biodiversity. The Central Mexican Pacific is an oceanographic region with mixed conditions from the North and South of the Mexican Pacific, and therefore, with a biogeographical importance reflected in its species richness.

Introducción: Los equinodermos del Pacífico Central mexicano poseen un alto interés científico, pero anterior al presente trabajo existía un vacío en la información básica como listados de especies incompletos con inconsistencias sistemáticas y de distribución espacial. Objetivo: Proporcionar una revisión histórica y un listado de especies actualizado con la riqueza completa de equinodermos para cada estado e islas de la región. Métodos: Se elaboró un listado de especies basado en una búsqueda exhaustiva de Echinodermata, y fue complementada con la revisión taxonómica de Ophiuroidea de colecciones científicas. Todas las coordenadas geográficas de los registros fueron validadas. Resultados: La región posee 187 especies de Echinodermata: tres Crinoidea, 35 Asteroidea, 67 Ophiuroidea, 32 Echinoidea, y 50 Holothuroidea. Detectamos 52 registros en la literatura considerados como inválidos y cinco como dudosos. Proveemos 16 nuevos registros de Ophiuroidea para diversos estados e islas; de estos, cuatro son nuevos registros para la región. Jalisco presentó el mayor número de especies (84), seguido por las costas de Nayarit (74), Michoacán (63), y Colima (55); entre las islas, Revillagigedo presentó el mayor número de especies (85) seguido por Marías (81), Marietas (48), e Isabel (44). Conclusiones: Los números de especies de la región están mayormente relacionados tanto con el esfuerzo de muestreo como con características ambientales que promueven una alta biodiversidad. El Pacífico Central mexicano es una región oceanográfica con condiciones mixtas del norte y sur del Pacífico mexicano, y por lo tanto con una importancia biogeográfica reflejada en la riqueza de la región.

Introduction: The Ophiuroidea class is the most diverse of the Phylum Echinodermata, with 2 064 described species, which can be found from intertidal zones to abyssal depths, but the fauna of Yucatan peninsula needs more study. Objective: To describe the diversity of ophiuroids in the Yucatan continental slope. Methods: Information was compiled from four oceanographic surveys carried out in August 2005, June 2007 (BIOREPES 1 and 2: BRP1 and BRP2), April 2011 and August 2014 (COBERPES 2 and 6: CBP2 and CBP6). The specimens were obtained by trawling with a shrimp net in soft substrates and with a skimmer-type trawl dredge at a depth range of 200 to 1 071 m off the states of Yucatán and Quintana Roo, Mexico. Results: We found members of two superorders, five orders, six suborders, five superfamilies, 18 families, 28 genera and 43 species. Conclusions: The northeast zone Yucatan Peninsula has at least 43 species, of which 19 are new records for the area.

Introducción: La clase Ophiuroidea es la más diversa del Phylum Echinodermata, con 2 064 especies descritas, que se pueden encontrar desde zonas intermareales hasta profundidades abisales, pero la fauna de la península de Yucatán necesita más estudio. Objetivo: Describir la diversidad de ofiuroideos en el talud continental de Yucatán. Métodos: Se recopiló información de cuatro estudios oceanográficos llevados a cabo en agosto de 2005, junio de 2007 (BIOREPES 1 y 2: BRP1 y BRP2), abril de 2011 y agosto de 2014 (COBERPES 2 y 6: CBP2 y CBP6). Los especímenes se obtuvieron mediante la pesca de arrastre con una red camaronera en sustratos blandos y con una draga de arrastre tipo skimmer en un rango de profundidad de 200 a 1 071 m frente a los estados de Yucatán y Quintana Roo, México. Resultados: Encontramos miembros de dos superórdenes, cinco órdenes, seis subórdenes, cinco superfamilias, 18 familias, 28 géneros y 43 especies. Conclusiones: La zona noreste de la Península de Yucatán tiene al menos 43 especies, de las cuales 19 son nuevos registros para el área.

Panstrongylus rufotuberculatus (Champion, 1899) (Hemiptera, Reduviidae, Triatominae) in Rondônia, Brazil: A novel report

Abstract INTRODUCTION: This short communication presents a novel report on the occurrence of Panstrongylus rufotuberculatus in the Brazilian state of Rondônia. METHODS: Two specimens were collected inside dwellings and identified using dichotomous keys. RESULTS: The present study showed the extensive geographic distribution of P. rufotuberculatus and the increased number of species in the state of Rondônia. CONCLUSIONS: This new record of P. rufotuberculatus is important for understanding the epidemiology of Chagas disease because this species is found naturally infected with Trypanosoma cruzi. Studies on the ecology, biology, and vector-host-parasite interactions of this species are essential for surveillance programs.

Diversity of Cerambycidae (Insecta: Coleoptera) in the Cerrado of Central Brazil using a new type of bait / Diversidade de Cerambycidae (Insecta: Coleoptera) no Cerrado do Brasil Central utilizando um novo tipo de isca

Abstract: The Cerambycidae family (Insecta: Coleoptera) has approximately 38 thousand species. In Brazil, more than 4,300 species and 1,050 genera are registered, and despite the ecological and agricultural importance of this family, no study has yet been done in the Cerrado of the Distrito Federal (Brazil). The objective of this study was to evaluate the richness and abundance of Cerambycidae in the Cerrado area using two types of fruits (banana and pineapple), fermented with sugarcane juice, as bait and to verify whether the richness is influenced by climate variables. The work was carried out in an area of the cerrado sensu stricto at Água Limpa Farm in the Distrito Federal. Beetles were collected weekly using 40 bait traps with two types of fruits that remained in the field for 12 uninterrupted months (November 2013 to October 2014). The traps were installed 1.50 m above the ground level, distributed in four 80 m transects, and spaced 20 m apart. A total of 1,599 individuals, belonging to 13 genera and different 19 species, were collected. The main species were as follows: Oxymerus basalis (Dalman, 1823) representing 78.3%, Retrachydes thoracicus thoracicus (Olivier, 1790) representing 9.9%, and Chydarteres bicolor (Fabricius, 1787) representing 4.5% of the total specimens collected. There was a significant difference in richness and abundance of Cerambycidae among the baits evaluated, with the pineapple bait presenting the highest values. The greatest number of individuals and species occurred soon after the first rains, especially in November. Temporal variation was confirmed through Rayleigh's uniformity test, following the seasonality of the Cerrado, with the greatest number of individuals and species found in the rainy season. Temperature and humidity influenced the richness of cerambycid beetles. This is the first work carried out with pineapple fermented with sugarcane juice as bait to capture Cerambycidae, and this type of bait proved to be efficient for the collection of insects, comparable in efficiency to the synthetic baits that are normally used. All species collected were new distribution records for the Distrito Federal (Brazil).

Resumo: A família Cerambycidae (Insecta: Coleoptera) possui aproximadamente 38 mil espécies. No Brasil são registradas mais de 4.300 espécies e 1.050 gêneros e, apesar da importância ecológica e agrícola desta família, ainda não foram realizados trabalhos no Cerrado do Distrito Federal. O objetivo deste trabalho foi avaliar a riqueza e abundância de Cerambycidae utilizando dois tipos de frutas (banana e abacaxi) fermentadas com caldo de cana em área de cerrado e verificar se a riqueza é influenciada pelas variáveis climáticas. O trabalho foi realizado em uma área de cerrado sensu stricto na Fazenda Água Limpa (FAL) em Brasília, Distrito Federal. A coleta de adultos de Cerambycidae foi realizada semanalmente usando 40 armadilhas iscadas com os dois tipos de frutas que ficaram em campo por 12 meses ininterruptos (novembro de 2013 a outubro de 2014). As armadilhas foram instaladas a 1,50 m do nível do solo, distribuídas em quatro transectos de 80 m e espaçadas 20 m entre si. Foram coletados 1.599 indivíduos, 13 gêneros e 19 espécies. As principais espécies foram Oxymerus basalis (Dalman, 1823) com 78,3% do total de espécimes coletado, Retrachydes thoracicus thoracicus (Olivier, 1790) com 9,9% e Chydarteres bicolor (Fabricius, 1787) com 4,5%. Houve diferença significativa na riqueza e abundância de Cerambycidae entre as iscas avaliadas, sendo a isca de abacaxi a que apresentou os maiores valores. O maior número de indivíduos e de espécies ocorre logo após as primeiras chuvas, principalmente no mês de novembro. A variação temporal foi confirmada através do teste de uniformidade de Rayleigh que acompanha a sazonalidade do Cerrado, com maior número de indivíduos e de espécies na estação chuvosa. A temperatura e umidade são as variáveis climáticas que influenciaram a riqueza de cerambicídeos. Este é o primeiro trabalho realizado com abacaxi fermentado com caldo de cana para captura de Cerambycidae, e este tipo de isca se mostrou eficiente para a coleta dos insetos, podendo ser comparado com as iscas sintéticas que normalmente são utilizadas. Todas as espécies coletadas são novos registros de distribuição para o Distrito Federal.

The Families Lecanoraceae, Parmeliaceae and Teloschistaceae presented the greatest number of genera, while the genera Buellia, Lecanora and Umbilicaria recorded higher species richness. Crustacean lichens were dominant (61% of the total), followed by foliose (32%) and fruticose (7%).

Composition and richness of monogonont rotifers from La Plata River Basin, South America / Composição e riqueza de rotíferos Monogononta da Bacia do Rio da Prata, América do Sul

Abstract: We present here the first study that analyzed the composition and richness of rotifers of the entire La Plata River basin, the second largest in South America, based on simultaneous and standardized sampling. Fifteen large reservoirs and eight river stretches were selected in the upper, middle, and lower portions of the Paraná, Paraguay, and Uruguay Rivers, which are the major rivers of the La Plata basin. We took a total of 86 samples (open water habitats) in 2010. A mean of 27±11 species per sub-basin was found, with the highest richness in the Lower Paraná (41 species), followed by the Paranapanema (40 species) and Lower Uruguay (38 species). Low richness was observed in the Middle Uruguay and Middle Paraná. We found 106 species belonging to 21 families and two orders. The family with the highest number of species was Lecanidae (21), followed by Brachionidae (20), Trichocercidae (9), and Synchaetidae (8). The species with higher occurrences were Conochilus dossuarius, Kellicottia bostoniensis, Keratella americana, Keratella cochlearis and Hexarthra mira. New occurrences of rotifers were registered for Brazil (Colurella adriatica), São Paulo State (Enteroplea lacustris), and Argentina (Gastropus hyptopus, Harringia rousseleti and Lecane thienemanni). Spearman correlation between the number of species and physical and chemical variables demonstrated positive correlation with chlorophyll and temperature, and negative correlation with dissolved oxygen. We extend the distribution list for some native (Lecane ludwigii) and non-native species of rotifers (K. bostoniensis). We also list the monogonont rotifer species found at the sampling stations.

Resumo: Apresentamos aqui o primeiro estudo que analisou a composição e riqueza de rotíferos de toda a bacia do Rio da Prata, a segunda maior da América do Sul, com amostragens simultâneas e padronizadas. Quinze grandes reservatórios e oito trechos lóticos foram selecionados nas porções alta, média e baixa dos rios Paraná, Paraguai e Uruguai, que atuam como os principais formadores da bacia do Prata. Coletamos um total de 86 amostras (habitats de águas abertas) em 2010. Foi encontrada uma média de 27 ± 11 espécies por sub-bacia, com maior riqueza no Baixo Paraná (41 espécies), seguido por Paranapanema (40 espécies) e Baixo Uruguai (38 espécies). Uma baixa riqueza foi observada no Médio Uruguai e no Médio Paraná. Encontramos 106 espécies pertencentes a 21 famílias e duas ordens. A família com maior número de espécies foi Lecanidae (21), seguida por Brachionidae (20), Trichocercidae (9) e Synchaetidae (8). As espécies com maior ocorrência foram Conochilus dossuarius, Kellicottia bostoniensis, Keratella americana, Keratella cochlearis e Hexarthra mira. Novas ocorrências de rotíferos foram registradas para o Brasil (Colurella adriatica), Estado de São Paulo (Enteroplea lacustris) e Argentina (Gastropus hyptopus, Harringia rousseleti e Lecane thienemanni). A correlação de Spearman entre o número de espécies e as variáveis físicas e químicas demonstrou correlação positiva com clorofila e temperatura, e correlação negativa com oxigênio dissolvido. Estendemos a lista de distribuição para algumas espécies nativas (Lecane ludwigii) e não-nativas de rotíferos (K. bostoniensis). Disponibilizamos também uma lista de espécies de rotíferos Monogononta encontrados nas estações amostradas.

Clave taxonómica de ninfas de Ephemeroptera(Insecta) del sudeste de Perú / Taxonomic key of nymphs of Ephemeroptera (Insecta) from southeastern Peru

Ephemeroptera es un orden de insectos cuyas etapas inmaduras cumplen un importante papel ecológico en los ecosistemas acuáticos. Sin embargo, el conocimiento de su diversidad en áreas tropicales aún es escaso. Específicamente, en el Perú se han reportado 64 especies pertenecientes a 35 géneros y ocho familias. En este estudio se presenta una clave taxonómica para la determinación de géneros de ninfas de Ephemeroptera de la vertiente suroriental de los Andes del Perú. Las ninfas revisadas fueron recolectadas en las quebradas de los departamentos de Cusco y Madre de Dios, dentro de un gradiente altitudinal de 180 - 4411 m, en los años 2012, 2013, 2015 y 2017. Se utilizaron tres metodologías de muestreo: recolección manual, red Surber y colonización de paquetes de hojas. Se reconocieron 48 géneros de ocho familias en 36 quebradas dentro de este gradiente. Seis géneros son nuevos registros para el Perú: Prebaetodes, Zelusia, Meridialaris, Tricorythopsis, Homoeoneuria y Hubbardipes.

Ephemeroptera is an insect order of whose immature stages play an important ecological role in aquatic ecosystems. However, its diversity knowledge in tropical areas is scarce. In particular, only 64 species of 35 genera and eight families have been reported in Peru. In this work, we provide a general key of Ephemeroptera nymphs for southeastern Peru. Nymphs were collected from streams of Cusco and Madre de Dios departments, within an altitudinal gradient of 180 - 4411 m, in 2012, 2013, 2015 and 2017 years. The samples were obtained by manual collection, using a Surber net and by colonization of leaf packs. We recognized 48 genera within eight families, coming from 36 streams within the gradient. Six genera are new records to Peru: Prebaetodes, Zelusia, Meridialaris, Tricorythopsis, Homoeoneuria and Hubbardipes.

First record of Glycera guatemalensis and G. sphyrabrancha (Annelida: Glyceridae) from Western Mexico

Introduction: Glycerides, commonly called "blood worms", are relatively thin polychaetes that reach considerable sizes. They have been reported for all the seas of the world from the intertidal zone to abyssal depths. Objective: Evidence the presence of two species of Glycera for the littorals of the Mexican Pacific. Methods: An analysis of the glycerides of the Pacific coast of Mexico was carried out, finding two species that were collected, one of shrimp trawl at a depth of 18 meters off Puertecitos, Baja California, as well as by manual sampling in the intertidal zone of Concepción Bay, Baja California Sur in the Gulf of California. For their taxonomic determination, morphological characters of greater relevance for their identification were examined, such as jaws, aileron shape, parapodia, chaetae, and the type of pharyngeal papillae. Results: We diagnosed and schematized Glycera guatemalensis Böggemann & Fiege, 2001 and Glycera sphyrabrancha Schmarda, 1861. Conclusions: Glycera guatemalensis described for Guatemala and Glycera sphyrabrancha described for Jamaica, are recorded for the first time for the Gulf of California.

Introducción: Los Glicéridos son llamados comúnmente "gusanos de sangre", son poliquetos relativamente delgados que alcanzan tallas considerables. Han sido reportados para todos los mares del mundo desde la zona de entremareas hasta profundidades abisales. Objetivo: Evidenciar la presencia de dos especies de Glycera para los litorales del Pacífico mexicano. Métodos: Se realizó un análisis de los glicéridos de la costa del pacífico de México, encontrando dos especies que fueron recolectadas, una de arrastre camaronero a una profundidad de 18 metros frente a Puertecitos, Baja California, así como mediante muestreo manual en la zona de entremareas de bahía Concepción, Baja California Sur en el golfo de California. Para su determinación taxonómica se examinaron los caracteres morfológicos de mayor relevancia para su determinación, como mandíbulas, forma del aileron, parapodios, setas, branquia, y tipo de papilas faríngeas. Resultados: En este trabajo se diagnostican y esquematizan Glycera guatemalensis Böggemann & Fiege, 2001 y Glycera sphyrabrancha Schmarda, 1861. Conclusión: Glycera guatemalensis descrita para Guatemala y Glycera sphyrabrancha descrita para Jamaica, se registran por primera vez para el golfo de California.

Nuevos registros de Microtrypes Kuschel y nuevas localidades para Rhinotrypes Kuschel (Coleoptera, Curculionidae, Entiminae) en Perú, con una clave de identificación / New records of Microtrypes Kuschel and new locations of Rhinotrypes Kuschel (Coleoptera, Curculionidae, Entiminae) from Peru with an identification key

Se reportan por primera vez para Perú tres especies de Microtrypes Kuschel: M. convexicollis Kuschel, M. coriaceus Kuschel y M. curvipes Kuschel. Además. se registran nuevas localidades para dos especies de Rhinotrypes Kuschel: R. grossepunctatus Kuschel y R. laevigatus Kuschel. Se incluye una clave de identificación para las especies de estos dos géneros.

Three species of Microtrypes Kuschel are reported for the first time in Peru: M. convexicollis Kuschel, M. coriaceus Kuschel, and M. curvipes Kuschel. New localities are recorded for two species of Rhinotrypes Kuschel: R. grossepunctatus Kuschel and R. laevigatus Kuschel. Those species correspond to the tribe Premnotrypini (Coleoptera, Curculionidae, Entiminae). An identification key for the species in both genera is included.

New systematic position of Itatingamyia Albuquerque (Diptera, Muscidae) based on molecular evidence, and description of the female of I. couriae

ABSTRACT ItatingamyiaAlbuquerque, 1979 is rare in collections, with only nine specimens preserved in museums. Two species are known, and their placement within Muscidae was never tested using molecular data. Here, we estimate the position of Itatingamyia within Muscidae with mitochondrial (COI) and nuclear (AATS, CAD, and EF1-α) markers using Maximum likelihood and Bayesian posterior probabilities as optimality criteria. According to our results, we propose to classify Itatingamyia as a Cyrtoneurininae. We also describe the previously unknown female and egg of Itatingamyia couriaeHaseyama and de Carvalho, 2011 and expand the known distribution of this species to the state of Minas Gerais, Brazil, through the discovery of 13 new specimens there. We also argue that Itatingamyia distribution is restricted to Atlantic Forest areas.
