Range Description

Ischnocnema penaxavantinho is known from the type locality: Estação Ecológica do Panga (Panga), (19 11’ S; 48 24’ W, ca. 800 masl), municipality of Uberlândia, and Perdizes (Estação de Pesquisa e Desenvolvimento Ambiental Galheiro; about 19 12’ S, 47 10’ W; 700–1000 masl; 2840 ha), another municipality in the Triângulo Mineiro region, both in the state of Minas Gerais, Brazil. Both localities are ca 130 km apart (Giaretta et al., 2007).

Habitat and Ecology

The vegetation at the type locality (Panga) includes several Cerrado physiognomies, including “Veredas” (a vegetation dominated by grass-like plants, with dispersed bushes and Mauritia flexuosa palms) and a riverine forest running along the Panga River (2 m wide). Human altered areas are covered by the exotic grass Brachiaria sp.. The local weather presents a hot and wet summer (Sep.–Mar.), and a cold and dry winter (Apr.–Aug), when frosts may occur. Males were heard calling on the ground or perched (up to 60 cm height) amidst dense tufts of natural grass-like herbs in Veredas or on Brachiaria sp. Up to 200 m from permanently wet soil. Rarely, when fires cleared open areas from
grasses, males were heard also from within forests or forest borders. Calling activity was observed between October and March, being most intense in the afternoon and first hours of the night (Giaretta et al., 2007).
