Anuran larvae, which are otherwise simple in shape, typically have complex keratinized mouthparts (i.e. labial teeth and jaw sheaths) that allow them to graze upon surfaces. The diversity in these structures among species presumably reflects specializations that allow for maximal feeding efficiency on different types of food. However, we lack a general(More)
The genus Chiasmocleis Méhely comprises 29 species distributed from Panama to tropical South America clustered in five clades: C. albopunctata, C. bassleri, C. hudsoni, C. shudikarensis and C. ventrimaculata (Peloso et al. 2014). Chiasmocleis schubarti Bokermann belongs to the C. albopunctata clade, which also includes C. alagoana Cruz, Caramaschi, and(More)
The purpose of this study was to determine the effects of the benzodiazepines, midazolam and chlordiazepoxide, and the barbiturate, pentobarbital, on spatial learning, in a within-subject, repeated-acquisition and performance procedure adapted to the Morris Swim Task. In the presence of one stimulus arrangement, rats learned to swim to a hidden escape(More)
The Odontophrynus americanus species group is a complex of diploid and tetraploid species hardly distinguished by morphological characters. It currently consists of three allopatric diploid species (i.e. O. cordobae, O. lavillai, and O. maisuma) and one widely distributed tetraploid species (i.e. O. americanus). We herein describe a new diploid allopatric(More)
We describe the external morphology and oral cavity of the tadpoles of Bokermannohyla caramaschii and B. diamantina respectively from the states of Espírito Santo and Bahia, Brazil. Larvae of both species are distinguished from each other by external characters such as body shape, labial tooth-row formula, number of marginal papillae, coloration and(More)
We describe Scinax pombali sp. n. a new species of treefrog of the Scinax catharinae group from Serra da Canastra, municipality of Capitólio (20°36'03''S, 46°17'34.9''W, 987 m a.s.l.), located in the Cerrado domains of the State of Minas Gerais, Southeastern Brazil. The new species is characterized by its small size, blotches and color pattern on dorsal(More)
In this paper, we describe a new species of the Leptodactylusfuscus group on the basis of adult morphology and advertisement call, occurring restricted to montane rock fields of the Chapada Diamantina, northern portion of the Espinhaço Range, central State of Bahia, northeastern Brazil. In addition, we re-describe the advertisement call ofL. camaquara from(More)
