Abstract:São aqui apresentados dados sobre a biologia de Cinomops abrasus (Temminck, 1826) com base em 36 exemplares capturados no Estado do Rio de Janeiro, sudeste do Brasil, entre 1993 e 1997, em quatro diferentes localidades.
“…The neotropical dog‐faced bats from the genus Cynomops Thomas, (Chiroptera: Molossidae) are fast‐flying aerial insectivores that hunt in open spaces, usually above the canopy level in forested habitats (Kalko et al . ), and form small colonies of less than 15 individuals (Vizotto & Taddei ; Esbérard & Bergallo ). Due to their foraging behaviour and low local abundance, Cynomops is rarely captured in ground level mist‐nets and consequently little represented in collections (Peters et al .…”
The low representativeness of the dog‐faced bats (genus Cynomops Thomas, ) in collections has constrained the study of the diversity and the evolutionary relationships within this genus. Taxonomic revisions of some taxa, in particular the large‐sized Cynomops abrasus (Temminck, ), are crucial for understanding the phylogeny of Cynomops. A total of four subspecies of C. abrasus have been described to date, all widespread in South America: C. a. mastivus (Thomas, ), C. a. brachymeles (Peters, 1865), C. a. cerastes (Thomas, ) and C. a. abrasus (Temminck, ). Here, we evaluated the phylogenetic relationships within Cynomops, and the status of the four C. abrasus subspecies using complete sequences of two mitochondrial genes (Cyt b and COI) and 39 morphological characters. Maximum‐parsimony, maximum‐likelihood and Bayesian phylogenetic reconstructions recovered a novel hypothesis for Cynomops, supported the recognition of C. a. mastivus as a distinct species, separated from C. abrasus, and two hypotheses of lineages previously unrecognized for Cynomops. The use of mitochondrial genes combined with morphological characters revealed again to be a powerful tool to recover the phylogenetic relationships within Cynomops and demonstrated that the genus is more diverse than previously thought.

The southern dog-faced bat, Cynomops planirostris (Peters, 1866), is a molossid that occurs from Colombia, Venezuela, and the Guianas, through Peru, Bolivia, and Brazil to Paraguay and Argentina. It is insectivorous, inhabiting areas near rivers and forests. The species is characterized by having a chest and venter with a white or cream-colored spot, a broad upper lip that projects forward, and ears almost touching at their base. Cynomops planirostris is presently listed as “Least Concern” (LC) by the International Union for Conservation of Nature Red List of Threatened Species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
