Two new records of Pseudis tocantins Caramaschi and Cruz 1998 (Anura, Pseudidae) in central Brazil

Abstract

Pseudis tocantins was described by Caramaschi and Cruz (1998) based in individuals from the municipality of Porto Nacional, state of Tocantins, collected in 1947. At present, this species is known only from its type locality (Caramaschi and Cruz 1998, Frost 2002). Along the years 1999 and 2001, P. tocantins was observed several times on large and vegetated permanent ponds in the Tocantins river valley, between the cities of Porto Nacional and Palmas (Brandao and Peres Jr. 2001). However, this area was flooded by the reservoir of the Luis Eduardo Magalhaes hydroelectric dam, in 2002. The formation of the lake, with 62.000 ha, destroyed the habitats used by P. tocantins, and probably causing its local extinction (i.e. the type population loose) (Brandao and Peres Jr. 2001). Herein, we present two new records of P. tocantins from states of Mato Grosso and Goias. The species identifications were confirmed comparing the animals with topotypes and with the original description. All collected animals were deposited at Colecao Herpetologica da Universidade de Brasilia (CHUNB).
