Amphibia, Anura, Leiuperidae, Physalaemus erythros Caramaschi, Feio and Guimarães-Neto, 2003: distribution extension

The Neotropical frog genus Physalaemus Fitzinger, 1826 currently comprises 42 species (Frost 2009) divided into seven species groups: P. cuvieri group, P. signifer group, P. albifrons group, P. deimaticus group, P. gracilis group, P. henselii group, and P. olfersii group (Nascimento et al. 2005). Species of this genus occur from southern Mexico to northern Argentina (Frost 2009). Physalaemus erythros was recently described (Caramaschi et al. 2003) based on one male and two female individuals, and currently only eight specimens are known (Appendix 1). Recently, Baeta et al. (2007) described the tadpole, advertisement call, and provided some notes on the natural history of P. erythros. On 30 October 2008, we collected a gravid female of P. erythros, snout-vent length 23.3 mm (Figure 1), at the edge of Corrego Verruguinha, Reserva Particular do Patrimonio Natural Serra do Caraca (RPPN Serra do Caraca), municipality of Catas Altas (20°08'28" S, 43°28'5" W; 1676 m above sea level), state of Minas Gerais. The habitat is a small river in an altitudinal rocky field plateau (a typical Brazilian campo rupestre). The river has a rocky bed and forms some pools and small waterfalls. The sparse vegetation consists of small trees and grasses. Other species occurring in the area are Bokermannohyla martinsi (Bokermann, 1964), Vitreorana eurygnatha (A. Lutz, 1925), and Iscnocnema aff. lactea.
