Taxonomy. Five species of Cynomops Thomas, 1920 are registered in Brazil: C. abrasus (Temminck, 1826) , C. greenhalli Goodwin, 1958 , C. milleri (Osgood, 1914) , C. mastivus (Thomas, 1911) and C. planirostris (Peters, 1866) ( Nogueira et al. 2014, Moras et al. 2018). Cynomops abrasus and C. mastivus can be readily distinguished from its congeners by size (forearm> 41 mm in C. abrasus and C. mastivus , and <39 mm in the other three species) ( Peters et al. 2002, Eger 2008, López-Baucells et al. 2016, Moras et al. 2018). Cynomops abrasus can be differed from the northern South American C. mastivus by the gracile and small skull (robust in C. mastivus ); the smooth slope of the anterior face of the lacrimal ridges on the forehead (there is an abrupt angle in C. mastivus ); and by the presence of deep and narrow trigonid on the M 1 (shallow and wide in C. mastivus – Moras et al. 2016, 2018). The specimen from PECB (ZSP 021; see Table 8 for measurements) have general reddish dark-brown fur, and cinnamon-brown venter; flattened muzzle; upper incisors separated and resembling canines in shape; ears rounded and separated; and a rounded antitragus, without a constriction at the base. The skull characters are in agreement with the diagnosis provided by Moras et al. (2016, 2018).

Distribution. In Brazil, the species is recorded in all biomes, except Pampas, in the states of Goiás, Maranhão, Minas Gerais, Mato Grosso do Sul, Mato Grosso, Pará, Paraíba, Piauí, Rio de Janeiro, Santa Catarina, and São Paulo ( Tavares et al. 2008, Reis et al. 2017). In of São Paulo, the species is also widely distributed, occurring in all the vegetational formations ( Garbino 2016).

Field observations.In December we captured an adult male in a roosting site on a building roof in sampling site S7 (Appendix 1). At the same roosting site we captured eleven individuals of Molossus molossus and one Molosssus rufus .
