Platyrrhinus guianensis is bat with a distribution restricted to the Guiana Region of South America in Guyana and Suriname. Herein, we report the southernmost record of this species, extending its distribution to Brazil in Brazilian Amazon. Our record indicates that the species have a larger geographical range that previously thought. Platyrrhinus guianensis occurs in sympatry with Platyrrhinus brachycephalus, Platyrrhinus incarum, and Platyrrhinus fusciventris in the Brazilian Amazon, and can be confused with these species, raising the possibility that there might be other specimens of Platyrrhinus guianensis misidentified as other species in scientific collections.
Gracilinanus microtarsus (J. A. Wagner, 1842), called the Brazilian gracile opossum, is a small didelphid that is 1 of 6 species in the genus Gracilinanus. It is a sexually dimorphic, solitary marsupial that has a highly seasonal reproductive pattern. It inhabits Atlantic rain forests and semideciduous forests interspersed in the highly seasonal cerrado (savanna-like vegetation) in southeastern and southern Brazil. It prefers locations associated with low canopy cover and it also occurs in habitats altered by anthropogenic events. The species is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources.
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.
