The Caatinga, an exclusive biome in Brazil, is the largest tropical dry forest area in the Americas. It is characterized by a semi-arid climate and various soils that harbor a great diversity of flora and fauna. Novel records of aerial insectivorous bat species in the family Molossidae in the Chapada Diamantina, northeastern Brazil are presented. The study is based on field sampling of 115 molossid bat specimens from six genera and 12 taxonomically confirmed species, along with four taxa requiring further evaluation for definitive species identification. All specimens were obtained using mist nets around a small freshwater lagoon surrounded by semideciduous dry forest. The verified genera were , , , , , and . Our findings enhance the understanding of bat diversity in the Brazilian Caatinga, with the first records of , , and . The most abundant species were , , , , and . Previously unreported morphological and morphometric variations for these Caatinga taxa were examined. Additionally, information on sexual dimorphism in craniodental characteristics of and variations in the presence of the sagittal crest in are provided. Based on the voucher specimens from this study, the recognized number of species of Molossidae known from the Caatinga has increased to 21. Our results offer new insights into the taxonomy and biogeography of Neotropical molossids, highlighting their importance as members of bat communities in dry forest ecosystems from northeastern South America.
卡廷加是巴西独有的生物群落,是美洲最大的热带干旱森林地区。其特点是气候半干旱,土壤多样,拥有丰富多样的动植物群。本文介绍了巴西东北部钻石山地区犬吻蝠科食虫蝙蝠新记录。该研究基于对来自6个属、12个经分类确认的物种以及4个需要进一步评估以确定物种身份的分类单元的115个犬吻蝠科蝙蝠标本进行的野外采样。所有标本均使用雾网在一个被半落叶干燥森林环绕的小型淡水泻湖周围采集。经核实的属有、、、、、和。我们的研究结果增进了对巴西卡廷加地区蝙蝠多样性的了解,首次记录了、和。数量最多的物种是、、、、和。研究了这些卡廷加分类单元以前未报道的形态和形态测量变异。此外,还提供了关于和颅齿特征的两性异形以及中矢状嵴存在情况变异的信息。根据本研究的凭证标本,卡廷加地区已知的犬吻蝠科物种数量已增至21种。我们的研究结果为新热带犬吻蝠科的分类学和生物地理学提供了新的见解,突出了它们作为南美洲东北部干旱森林生态系统中蝙蝠群落成员的重要性。
