ABSTRACT The knowledge of the bat fauna from Minas Gerais, the largest state in southeastern Brazil, has greatly changed in recent years due to increased sampling and taxonomic revisions with reports of range extension and/or new species descriptions. The first annotated list of bats for the state dates to over 10 years ago. Our study aimed to update it by incorporating new localities sampled since then and by adding new species records to the list. We also conducted a comprehensive review of the literature and museum databases and analyzed 691 specimens collected in the state from all mesoregions and ecosystems deposited in collections. We documented the occurrence of 99 bat species from nine families, distributed in 181 municipalities, covering all mesoregions and biomes of the state. This is an increment of 30% in bat richness and of 241% in locality sites with bat records in Minas Gerais, when compared with the previous compilation. We report two previously unrecorded species for the state, the phylostomids Rhinophylla pumilio Peters, 1865 and Trinycteris nicefori (Sanborn, 1949). The mesoregions with the largest number of bat collection localities were “Metropolitana” (46), “Zona da Mata” (26), and “Norte de Minas” (21). The Atlantic Forest had the largest number of collection sites compared to the other biomes present in the state (102). There are a lot of sampling gaps in the state, and most of the conservation areas have not yet been sampled for bats. In face of that and based on the recent findings of several new species and records as a result of sampling and revisionary efforts, we suggest the implementation of rapid survey programs accompanied by taxonomic studies within the conservation units of Minas Gerais. Long-term monitoring programs, including bats, are also completely missing in the state.

Abstract The emperor tamarin, Tamarinus imperator, is composed of two subspecies, the nominal type, T. i. imperator, distributed between the Acre and Purus Rivers, whose range is limited between the Brazilian state of Acre and Peru are unbounded, and T. i. subgrisescens, occurring in Peru, Bolivia, and Brazil, in the Brazilian states of Acre and Amazonas. Morphologically, both taxa are easily identifiable by the pelage pattern (chromogenetic fields), and even being easily distinguishable, both lineages are considered subspecies according to the criterion based on the Biological Concept of Species from the 1970s, even without presenting some necessary criteria, such as the intergradation zone. Here we analyzed pelage traits, cranial morphometry, Cytochrome-b divergence, and distributional pattern data applying the premises of integrative taxonomy to elucidate the taxonomic status of both lineages. We hypothesize that both lineages are considered full species through a series of criteria for species recognition, such as distinguishability, level of phenotypical divergences of several morphological complexes with congruence among them, and some genetic divergence. The hybridization is unknown and the low or the lack of sampling in target areas does not allow us to determine whether a hybridization or even contact zone between the two lineages exists indeed. All character sets analyzed were congruent with each other and reinforced the high level of divergences between the two subspecies including several pelage differences, morphometry (descriptive statistics, PCA, and MANOVA), and mitochondrial DNA Cytochrome-b divergence. Most of the distribution in both lineages are allopatric, and the levels of intra-lineage phenotypical variation are much lower than between the lineages. tamarin imperator type T i Rivers unbounded subgrisescens Bolivia Brazil Amazonas Morphologically chromogenetic fields, fields , fields) distinguishable 1970s s traits Cytochromeb Cytochrome b divergence recognition distinguishability them indeed differences descriptive statistics PCA MANOVA, MANOVA MANOVA) allopatric intralineage intra lineage

Abstract Comparative morphological characters in Neotropical bats are mostly restricted to external and cranio-dentary complexes, and few studies focusing on other morphological complexes have been carried out. In the case of tongue morphology, comparative analyses of the structure have been restricted to the superfamily Noctilionoidea with a wide range of diets, and Molossidae, a strictly aerial insectivore family. In this paper, we studied the morphology of tongue papillae in 10 aerial insectivore Neotropical bat species, representing six families (Emballonuridae, Furipteridae, Thyropteridae, Mormoopidae, Natalidae, and Vespertilionidae), and data from the previous study of Molossidae were compared. We studied tongues in light and scanning electron microscopes following material preparation protocols. We observed two types of sensitive papillae, circumvallate and fungiform, the latter at times presenting a groove surrounding the papillae. Nine mechanic types were observed, one of them, which we called flaky-like, not hitherto described. All Vespertilionoidea families (Vespertilionidae, Natalidae, and Molossidae) presented, as diagnosing characters, fungiform papillae distributed throughout the tongue, as well as anteriorly at the dorsum, and scale-like papillae on the medial lobe directed laterally and anteriorly. Emballonuridae showed the simplest tongue morphology regarding the presence and abundance of some papillae. Families composing the clade Furipteridae + Thyropteridae + Mormoopidae presented small and non-grooved fungiform papillae, and mechanical bifid papillae were absent. In summary, this study has provided additional traits (putative synapomorphies) of the bat tongue to support the clades on the current bat phylogeny.

RESUMEN Datos sobre biología y distribución para algunas especies de murciélagos in Suramérica son escasos, principalmente para grupos no filostómidos. Proporcionamos nuevos registros de dos especies raras de murciélagos insectívoros para el sureste de Brasil, Histiotus montanus y Molossops neglectus. En adición, reportamos la variación de colores faciales y nuevos registros de ectoparásitos en Histiotus montanus. Para M. neglectus se aplicó un Análisis de Componentes Principales (ACP) para probar variación morfométrica con base en dimensiones craneales y de antebrazo, demostrando que las muestras del sur de la distribución tuvieron menores medidas que las del norte.

ABSTRACT Distributional and biological data for some bat species in South America are scarce, mainly in non-phyl-lostomid bats. Herein we provide new records of two rare species of aerial insectivore bats for southeastern Brazil, Histiotus montanus and Molossops neglectus. In addition, we report facial morphological variation in color and new records of ectoparasites for H. montanus. For M. neglectus we performed a Principal Component Analysis (PCA) to check for morphometric variation based on forearm and skull dimensions, the southerly distributed specimens showing slightly smaller measurements than the northern ones.

RESUMO O norte do estado do Mato Grosso é uma importante região para estudos biogeográficos com muitos hiatos de amostragem sendo a fauna de morcegos pobremente conhecida. O objetivo deste estudo foi fornecer uma lista de morcegos para o Parque Nacional do Juruena, norte do Mato Grosso, Brasil. Foram amostrados 19 sítios e empregadas redes-de-neblina ao nível do solo e próximos a abrigos potenciais de morcegos. Foram coletados 115 indivíduos representando 35 espécies e cinco famílias, aumentando de 86 para 91 o número de espécies conhecidas para a Amazônia no Mato Grosso. Houve cinco novos registros para a porção amazônica do estado: Peropteryx kappleri,Peropteryx leucoptera, Lonchorhina inusitata, Tonatia saurophila e Artibeus concolor. Os resultados indicam a necessidade de mais estudos para uma melhor estimativa da diversidade no norte do Mato Grosso.

ABSTRACT The northern Brazilian state of Mato Grosso is considered an important biogeographical region, but has many sampling gaps. Apart from the well-documented non volant mammal community in the region, the bat fauna still poorly recorded. The aim of this study was to record the bat species of Juruena National Park, northern Mato Grosso, Brazil. Nineteen sites were sampled using mist-nets placed at ground level and near potential bat roosts. We collected 115 individuals belonging to 35 species and five families, which increased the number of species known for Mato Grosso´s Amazon from 86 to 91. The five new records were: Peropteryx kappleri, Peropteryx leucoptera, Lonchorhina inusitata, Tonatia saurophila, and Artibeus concolor. Our results pointed out the necessity of more studies in order to better estimate the bat diversity in northern Mato Grosso.

Minas Gerais presents the richest bat fauna among the states of southeastern Brazil. Despite its high diversity, the bat fauna in large areas of the state remain poorly or completely unknown due to its wide territorial area, as well as the complexity of its relief and vegetation. This work aimed to study the bat fauna in fragments of a region in Lavras, Minas Gerais, southeastern Brazil, as well as the dynamic of their species. The study was carried out in a highly fragmented landscape area, composed by relatively small fragments of semi-deciduous forest under distinct levels of human disturbances. Forty nights of sampling were conducted with a total capture effort of 43 200 m²/h. Fourteen species were recorded out of which, 10 were in the family Phyllostomidae, 3 in Vespertilionidae and 1 in Molossidae. It is important to highlight the presence of Chiroderma doriae, a species classified as threatened in Brazil, and Molossops neglectus, a rare molossid bat that needs taxonomic review.

El estado de Minas Gerais es el estado más rico del sudeste de Brasil en cuanto a número de especies de murciélagos. A pesar de esta gran diversidad, grandes áreas del estado continúan siendo poco o completamente desconocidas en lo respectivo a los quirópteros, debido a la amplitud de su área territorial, al relieve y a la complejidad de la vegetación. El presente trabajo tuvo como objetivo estudiar los murciélagos en fragmentos de la región de Lavras, Minas Gerais, sudeste de Brasil, así como la dinámica de sus especies. El estudio se llevó a cabo en una zona de paisaje altamente fragmentado, compuesta por pequeños fragmentos de bosque semideciduo y en distintos niveles de antropización. Se realizaron muestreos durante 40 noches, con un esfuerzo de captura total de 43 200 m²/h. Catorce especies fueron registradas, de las cuales 10 correspondieron a la familia Phyllostomidae, 3 a Vespertilionidae y 1 a Molossidae. Es importante destacar la presencia de Chiroderma doriae, una especie clasificada como amenazada en Brasil y Molossops neglectus, un molósido muy raro que necesita de revisión taxonómica.

The Caatinga-endemic nectar-feeding bat, Xeronycteris vieirai Gregorin & Ditchfield, 2005 was described based on four specimens. Since then, only two additional specimens have been reported in the literature. Examination of a new specimen that closely agrees with the original description but presents two additional upper premolars, led us to review the type series of this taxon. Our analysis provided support to the recognition of the new specimen as a X. vieirai with supernumerary teeth and revealed new diagnostic characters that can help in the field identification of this species. Xeronycteris vieirai presents tricolored dorsal fur, entirely naked forearm, connection of the base of the spear of the noseleaf with the upper limit of the horseshoe with a marked ridge, and chin with simple dermal pads and a relatively slight cleft. Additional new characters described here include anterior zygomatic arches reduced and not extending laterally and upward with respect to upper toothrow, basioccipital pits deep and separated by a high and thin bone septum, and mandible with a pronounced ridge at anterior symphysis. We propose an emended diagnosis based on morphological characters and provide a rectification on the original notation related to the holotype.

Grande parte das paisagens brasileiras se encontra abaixo dos 600 m de altitude e os estudos sobre a rica fauna de morcegos brasileiros em elevadas altitudes são escassos. Nesse estudo, investigamos a assembleia de morcegos associada a diferentes habitats na Chapada do Abanador, Minas Gerais, cuja altitude varia de 1000 a 1580 m. Foram conduzidas 45 noites de amostragem (153 000 m2h) na floresta semidecidual montana, floresta nebular e campo de altitude. Foram capturados 137 indivíduos pertencentes a 12 espécies das famílias Phyllostomidae e Vespertilionidae, com grande predominância da primeira. Curvas de acumulação de espécies alcançaram valores próximos à assíntota para o campo de altitude e floresta nebular, mas não para a floresta montana, sugerindo que mais espécies seriam adicionadas com o aumento do esforço amostral nesse habitat. A análise de escalonamento multidimensional não-métrico não indicou forte separação entre os habitats. Entretanto, foi observada uma maior abundância de Desmodus rotundus e Histiotus velatus no campo de altitude, sendo a última exclusiva desse habitat. Além disso, foi observada uma maior abundância de frugívoros nos habitats florestados, enquanto hematófagos e insetívoros foram mais abundantes no campo de altitude. Embora apresentem menor riqueza de espécies quando comparados com ambientes abaixo de 1000 m, os campos de altitude e as florestas nebulares constituem porções ecologicamente importantes e pouco protegidas da Floresta Atlântica em Minas Gerais, cuja biodiversidade deve ser preservada. Nossos dados contribuem com uma melhor descrição da fauna local e preenche lacunas na distribuição de espécies para locais de elevada altitude no Brasil.

Most Brazilian landscapes lie below 600 m above sea level and studies on the rich Brazilian bat fauna at higher altitudes are scarce. In this study, we investigated bat assemblages associated with different habitats in Chapada do Abanador, Minas Gerais, an area with altitudes ranging from 1000 to 1580 m. Forty-five nights of sampling (153 000 m2h) were performed in semideciduous montane forest, cloud forest and campo de altitude. A total of 137 individuals were captured, belonging to 12 species of the families Phyllostomidae and Vespertilionidae, with a large dominance of the former. Species-accumulation curves reached values close to the asymptote for the campo de altitude and cloud forest habitats, but not for montane forest, suggesting that more species may be added by extending the sampling effort in this habitat. A non-metric multidimensional scaling analysis indicated no strong separation between sampled habitats. Higher abundances of Desmodus rotundus and Histiotus velatus in the campo de altitude were observed, with the latter being exclusively recorded in this habitat. Moreover, a higher abundance of frugivores was observed in forested habitats, while hematophagous, insectivores and nectarivores were more abundant in the campo de altitude. Although presenting lower species richness when compared with environments below 1000 m, the campos de altitude and cloud forests are ecologically important and poorly protected portions of the Atlantic Forest in Minas Gerais, whose biodiversity must be preserved. Our data contributes with a better description of the local fauna and fills gaps on the species distribution for high altitude sites in Brazil.

Este estudo relata o primeiro registro de Molossus coibensis J. A. Allen, 1904 para a Amazônia brasileira e o segundo para o Brasil. Ele também apresenta uma análise comparativa com outras duas espécies de Molossus de pequeno porte no Brasil: M. molossus (Pallas, 1766) e M. aztecus Saussure, 1860. O estudo é baseado em oito fêmeas capturadas em áreas urbanas da cidade de Bragança, no norte do estado do Pará. Dados morfométricos e comparação qualitativa de características morfológicas permitem a identificação dos espécimes como M. coibensis, até então conhecido apenas em Tapirapuã, no sudoeste do estado de Mato Grosso, Centro-Oeste do Brasil.

This study reports on the occurrence of Molossus coibensis J. A. Allen, 1904, in the Brazilian Amazon and the second record of this species from Brazil. It also presents a comparative analysis with other two small-bodied Molossus species that occur in Brazil: M. molossus (Pallas, 1766) and M. aztecus Saussure, 1860. The report is based on 8 females captured in urban areas of the city of Bragança, in the northern Brazilian state of Pará. Morphometric data and the qualitative comparison of morphological features permited the identification of the specimens as M. coibensis, hitherto known only in Tapirapoan, in the southwestern state of Mato Grosso, west-central Brazil.

A fauna de mamíferos do estado de São Paulo consta de 231 táxons, sendo este número uma estimativa da real diversidade presente na região, dado a falta de amostragem em grandes extensões do estado, e também de revisões taxonômicas para determinados grupos. Ainda assim, nosso conhecimento aumentou em 20% desde a última estimativa em 1998, principalmente em relação aos quirópteros e roedores. Estes dados são provenientes de inventários faunísticos, e também do estudo de espécimes depositados em coleções científicas oriundos de revisões taxonômicas. Também temos um maior volume de dados a respeito da distribuição dos mamíferos em relação às diferentes paisagens presentes no estado, o que nos permite dividir a mastofauna em três componentes distintos: o mais importante desses é o das espécies generalistas, que ocorrem em todas as principais paisagens do estado; o segundo grupo concentra espécies das formações abertas, e o terceiro grupo inclui as espécies essencialmente florestais. Além disso, o número de estudos que tem se preocupado com o efeito da fragmentação de hábitats sobre as comunidades de mamíferos, bem como a respeito da permeabilidade das espécies em áreas alteradas, também aumentaram. Dados a respeito da ocorrência, abundância e vulnerabilidade das espécies foram essenciais para traçar estratégias em relação à escolha de áreas e à indicação de ações prioritárias para a conservação dos mamíferos no estado, assim como classificar as espécies nas diferentes categorias de ameaças propostas, culminando na Lista das Espécies Ameaçadas do Estado de São Paulo. Entretanto, ainda existem inúmeras lacunas de conhecimento, que vão desde o número limitado de amostras zoológicas, até a falta de informações acerca da ecologia e história natural de várias espécies. É imprescindível que aumentemos as amostras de mamíferos em coleções zoológicas, principalmente em áreas de Floresta Ombrófila Densa, nos fragmentos de Cerrado, bem como em áreas do centro e oeste do Estado, que permanecem ainda pouco estudadas, com o objetivo de produzir um maior número de revisões taxonômicas em diversos grupos de mamíferos, e de estudos com abordagens filogeográficas e de genética de populações, para diagnosticarmos de forma efetiva a riqueza de mamíferos no estado, bem como os mecanismos evolutivos responsáveis por esta diversificação. Aliados a esses estudos serão necessárias abordagens ecológicas para gerarmos conhecimento, que em conjunto, nos permitirá avaliarmos o estado de conservação dos mamíferos de São Paulo e tomarmos decisões sobre as melhores estratégias para manejarmos e preservarmos estas espécies.

São Paulo harbors 231 mammal species until now. This is an estimate of its real diversity since many regions of the State continue poorly surveyed, and also reflects the lack of taxonomic work for certain mammal taxa. Nevertheless, our knowledge of the São Paulo mammals has increased in 20% in the last 12 years, especially in relation to bats and rodents. These new data are based in mammal inventories and also in the analysis of specimens housed in scientific collections associated with taxonomic revisions. We also know better about the mammal distribution in the distinct vegetation units present in the State, permitting us to divide the mammals in three distinct components: the most important one is the generalists, represented by species occurring in every landscape in the State, while the second one concentrates species inhabiting the open formations, and the third component the species associated with the forest formations. Besides, the number of studies dealing with the effect of fragmentation and the permeability of mammals in altered areas also has increased. Occurrence, abundance and vulnerability data were essential to raise strategies in order to choose priority areas and to indicate priority actions to conserve the mammals of the State, as well as to classify the species in the different proposed threaten categories, culminating in the List of the Threaten Species of the São Paulo State. However, there are many points yet poorly developed or poorly known, such as the limited number of zoological samples, and the lack of information about the ecology and natural history of many species, respectively. It's extremely important that we increase our samples in the scientific collections, especially in areas of Dense Ombrofilous Forests, in the Cerrado fragments, as well as in central and western areas of the State that continue poorly surveyed. The objective is to produce more taxonomic work in several mammalian groups, and also studies focusing in the phylogeography and in the population genetics in order to effectively diagnose the mammal richness of the State, as well as the evolutionary processes responsible for this diversification. Additionally, ecological data accompanying this information is needed in order to evaluate the conservation status of the São Paulo mammals to decide about the better strategies to manage and conserve these mammals.

Brazil is the second most bat species-rich country in the world, but the information on its species diversity, occurrence and distribution is still heterogeneous and fragmented. None of the Brazilian biomes are well surveyed for bats, but this situation is more critical in Amazonia, an area covering nearly 2/3 of the country. Here we provide updated information on the bats of Amapá, once a data gap in the diversity and distribution of bats in the easternmost Amazonia, and the Guiana Shield as well. Rapid biological assessments (5,551 mistnet.hours) were conducted in conservation units and areas of concern, resulting in 1,695 captures, 59 species, 36 genera and six families for the State. New records for the state and for the Guiana Shield area are reported. With our records, 82 species of bats are currently known in Amapá, filling a gap in the knowledge of bat fauna in the Amazon River's delta region.

Inventários e estudos faunísticos detalhados sobre vertebrados são uma das fontes mais relevantes de dados para interpretações de padrões detalhados de diversidade biológica. Dados básicos e de boa qualidade sobre faunística são ainda mais urgentes em regiões pouco estudadas e sob intensa ameaça antrópica, tais como a região do Cerrado, um dos 34 hotspots globais para a conservação da biodiversidade. Apresentamos aqui uma síntese dos resultados dos inventários de vertebrados na Estação Ecológica Serra Geral do Tocantins (~716.000 ha), a segunda maior unidade de conservação em todo o Cerrado. Foram registradas 450 espécies de vertebrados na EESGT e entorno imediato, incluindo 17 espécies ameaçadas, 50 espécies endêmicas do Cerrado e 11 espécies com distribuição potencialmente restrita. Do total de espécies amostradas, 180 são novos registros para a região do Jalapão. Ao menos 12 espécies amostradas foram consideradas potenciais espécies novas, das quais quatro foram descritas recentemente, a partir do material obtido no inventário. Os resultados evidenciam que a EESGT é uma das mais importantes áreas protegidas no Brasil central, contribuindo para a persistência de espécies ameaçadas, dependentes dos últimos grandes blocos contínuos de vegetação nativa de Cerrado. Nossos resultados indicam ainda que a conservação da EESGT e suas principais subunidades é crucial para a representatividade do sistema de áreas protegidas do Cerrado, protegendo potenciais endemismos restritos que aliam alta vulnerabilidade intrínseca e valor como indicadores de padrões e processos biogeográficos formadores da rica e cada vez mais ameaçada fauna Neotropical.

Basic taxonomic and distributional data on vertebrates are one of the most useful and reliable sources of information for conservation planning. Biological data are even more relevant in rich and highly threatened regions such as the Brazilian Cerrado, one of the least studied global biodiversity hotspots. Herein we provide a summary of the results of a vertebrate survey at Estação Ecológica Serra Geral do Tocantins (~716.000 ha), the second largest protected area in the Cerrado region. We recorded 450 species in EESGT and surroundings, including 17 threatened species, 50 Cerrado endemics and 11 potential restricted-range species. Our results also added 180 new vertebrate records for the Jalapão region. At least 12 species were considered potential undescribed taxa; four of these were recently described based on specimens obtained in the present study. Our results indicate that EESGT is among the most biologically relevant protected areas in the Cerrado. Proper management will favor the persistence of threatened vertebrates dependent on the last remaining large blocks of pristine Cerrado savannas. Moreover, EESGT and its major biological subunits contribute decisively to the representativeness of the reserve system in the Cerrado, conserving presumed narrow endemics with high intrinsic vulnerability and high potential value as indicators of biogeographic processes of diversification in rich and complex Neotropical biotas.

Registramos 39 espécies de quirópteros na Estação Ecológica Serra Geral do Tocantins e áreas adjacentes, nordeste do estado do Tocantins, durante 28 dias de trabalho de campo nos anos de 2003 e 2008 e na estação chuvosa. Este estudo da quiropterofauna é um dos primeiros para o estado do Tocantins, aumentando o número de espécies conhecido para esta região, com 29 espécies registradas pela primeira vez no estado. As espécies mais abundantes foram P. lineatus e C. perspicillata, com 23,5 e 15,4% do total de capturas. A diversidade no nível de família também foi alta: Phyllostomidae (26 espécies), Vespertilionidae (5), Molossidae (3), Emballonuridae (2), Mormoopidae (1), Noctilionidae (1) e Thyropteridae (1). A maioria das áreas mésicas e de cerrado (s.s.) não estão incluídas em unidades de conservação, representando uma ameaça para espécies restritas a estes tipos de hábitats, como T. devivoi que foi capturada apenas em áreas de veredas com Heliconiacea. Além disso, a região vem sendo alterada devido ao rápido avanço da agricultura e pastagens e do turismo crescente. Assim, a elevada diversidade de morcegos registrada na região, além dos diversos papéis ecológicos que estas espécies desempenham, somadas às ameaças acima relatadas, aumentam as prioridades em se estabelecer estratégias de conservação para este grupo de mamíferos nas regiões adjacentes à Estação Ecológica Serra Geral do Tocantins. Dentre as espécies com interesse taxonômico, biogeográfico e de conservação destacam-se Lonchophylla dekeyseri, Glyphonycteris behnii, Micronycteris sanborni, Artibeus anderseni, Sturnira tildae e a recém-descrita Thyroptera devivoi.

During 28 days of field work in rainy season in 2003 and 2008, 39 species of bats were recorded in the Estação Ecológica Serra Geral do Tocantins, northeastern State of Tocantins. This is one of the first studies about bat communities in the State of Tocantins increasing the number of species known to occur in that Federal unit, with 29 species representing the first occurrence for the State. Frugivores P. lineatus and C. perspicillata were the most common species in the community, with 23.5 and 15.4% of total captures. Diversity at the family level also was high with seven families recorded: Phyllostomidae (26 species), Vespertilionidae (5), Molossidae (3), Emballonuridae (2), Mormoopidae (1), Noctilionidae (1), and Thyropteridae (1). Most of mesic and cerrado (s.s.) areas are not included in this Conservation Unit, imposing a problem for the conservation of habitat-restricted species like T. devivoi which was captured only in "veredas" with Heliconiacea until now. Additionally, the region is facing an increase in the tourism, agriculture and pasture activities. Due to the high expected bat diversity for the area, the known ecological functions played by bats, and the several human induced threats, there is urgency concerning the conservation strategies for this group of mammals in the vicinity of the Estação Ecológica Serra Geral do Tocantins. The species with high importance in relation to taxonomy, biogeography and conservation issues are: Lonchophylla dekeyseri, Glyphonycteris behnii, Micronycteris sanborni, Artibeus anderseni, Sturnira tildae and the recently described Thyroptera devivoi.

Há uma grande lacuna no conhecimento da biologia e corologia de Nyctinomops aurispinosus. Nesta comunicação, nós apresentamos o registro mais austral deste molossídeo, realizado na cidade de Curitiba (25° 25' S e 49° 15' W, 920 m), estado do Paraná, Brasil, e sumarizamos a distribuição geográfica conhecida para a espécie na América do Sul.

There is a lack of knowledge of the biology and distribution of Nyctinomops aurispinosus. Herein, we report the southernmost record of this species, from the city of Curitiba (25° 25' S and 49° 15' W, 920 m), state of Paraná, Brazil, and summarize its distribution in South America.

Foi analisada a morfologia quantitativa e qualitativa de 88 espécimes do subgênero Mimon previamente identificados como Mimon bennettii (Gray, 1838) e M. cozumelae Goldman, 1914 de diversas localidades dentro de sua distribuição. Os dados indicam que os espécimes de Mimon bennetii no Brasil apresentam variação geográfica nos caracteres morfométricos e em mosaico nos qualitativos. Espécimes do bioma Cerrado provenientes dos estados brasileiros do Piauí, Tocantins e Goiás têm antebraço mais longo que os indivíduos dos domínios da Amazônia e Floresta Atlântica. Com base na morfometria aplicando teste t-Student, os espécimes de M. bennettii do Cerrado lembram fenéticamente mais M. cozumelae que M. bennettii da Floresta Atlântica. Os caracteres morfológicos atualmente empregados para diagnosticar M. cozumelae também foram registrados para M. bennettii em diversas áreas do Brasil, tornando a validade de M. cozumelae questionável nesses tipos de caracteres. O presente artigo também atualiza a distribuição geográfica de M. bennettii no Brazil.

We studied discrete and quantitative data from 88 specimens of the subgenus Mimon previously identified as Mimon bennettii (Gray, 1838) and M. cozumelae Goldman, 1914 from diverse parts of their range. Our data indicate that specimens of Mimon bennetii in Brazil presented geographic variation in morphometrical characters and mosaic variation in qualitative traits. Specimens from the Cerrado biome collected in Brazilian states like Piaui, Tocantins, and Goiás have longer forearms than those distributed in the Atlantic and Amazon forested domains. Based on morphometrics, as showed by t-tests, specimens of M. bennettii from the Brazilian Cerrado resemble phenetically more with M. cozumelae than the M. bennettii from Atlantic Forest. Characters presently used to diagnosis M. cozumelae also were also recorded to M. bennettii in diverse parts of Brazil, making that validity of M. cozumelae questionable based on this kind of traits. This research also updated the geographic distribution to the M. bennettii in Brazil.
