Geographic Range [top]

Range Description:This species is only known from southeastern Brazil, and from Misiones province in Argentina (Davis 1947, Massoia 1980, Vieira 1949). Costa et al. (2003) demonstrated that this species occurs north into Minas Gerais state. Brown (2004) provided records south of Porto Alegre in Rio Grande do Sul state. Gardner (2008) did not recognize the localities in Misiones (Argentina) or Porto Alegre (Brazil), and the range needs clarification.

Population [top]

Population:This species has a restricted range. It is not as abundant as G. agilis, although it is not rare (L. Costa pers. comm.).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is found in wet evergreen Atlantic coastal forest in eastern Brazil. It was regularly caught on the ground as well as in trees, in both virgin and second-growth forest, though its morphology suggests extensive arboreality. It will probably be found to inhabit, almost exclusively, areas of moderate to high rainfall (Davis 1947, Stallings 1988, Tate 1933).

Use and Trade [top]

Use and Trade: There is no use or trade information.

Threats [top]

Major Threat(s): There are no presumed major threats. There is extensive deforestation in parts of its range.

Conservation Actions [top]

Conservation Actions: This species occurs in protected areas. More research is needed to define to true range of this species.
