Brazil has a fundamental role in amphibian conservation, harboring the highest amphibian species richness in the world and a large number of endemics. Here, we present an overview of the Brazilian Amphibian Conservation Action Plan (BACAP), which is still being developed by Brazilian herpetologists. Basic research - particularly species inventories, taxonomic revisions and the collection of field data - are urgently needed to guide amphibian conservation in the country. Documentation and monitoring of amphibian richness has improved, at least at regional scales. Lists of threatened species are regularly updated, efforts to standardize field work protocols are being attempted and captive breeding is being considered as a research and educational tool. We also present a short history of the BACAP, identify some of the challenges tied to its implementation, and review a few but important recent achievements. © ISSCA 2012.

The geographic distribution of Bokermannohyla lucianae, know only from its type locality in the municipality of Una, is extended 60 km south and 60 km south-west with two new localities in southern Bahia. The species seems to be restricted to remnants of primary and secondary Atlantic Rainforest patches in a small area of southern Bahia. © 2011 Check List and Authors.

The analysis of the external morphology variation in Crossodactylus bokermanni, C. trachystomus, and in unidentified specimens from 14 localities along the southern region of the Serra do Espinhaço, state of Minas Gerais, Brazil, revealed that all of these forms belong to the same taxon. Crossodactylus bokermanni is considered a junior synonym of C. trachystomus, whose holotype is redescribed and figured. The population from Serra da Canastra, western Minas Gerais, previously referred to as Crossodactylus cf. trachystomus, is herein described and figured as Crossodactylus franciscanus. Its advertisement call is redescribed and compared to those known for the genus. Copyright © 2015 Magnolia Press.

Bokermannohyla nanuzae (Bokermann & Sazima 1973) and B. feioi (Napoli & Caramaschi 2004) belong to the B. circumdata species group. The type locality of the former is Serra do Cipó, Espinhaço mountain range, and of the latter is Parque Estadual do Ibitipoca, Mantiqueira mountain range, both in Minas Gerais State, Brazil. Differences on dorsal drawing pattern of adults, oral disc morphology of tadpoles, and temporal properties of calls were proposed to distinguish these two species. However, several specimens found between the two type localities remain unidentified because diagnostic characters and states occur in all of these populations. Thus, in order to assess these characters variations, we performed an analysis of the morphology and morphometry of adults, vocalization, and morphology of tadpoles. Specimens were divided into three operational taxonomic units (OTUs): B. nanuzae (Serra do Cipó and northwards, Espinhaço mountain range), B. cf. nanuzae (Quadrilátero Ferrífero, Espinhaço mountain range, south of Serra do Cipó), and B. feioi (Serra do Ibitipoca, Mantiqueira mountain range). Drawing patterns of the dorsum and limbs show clinal variation and the three units are morphometrically very similar. Temporal and spectral properties of calls overlap in these three units. The diag nostic differences originally proposed for tadpoles are intrapopulational variations and occur in specimens from all of the locations analyzed. We found that these three units are morphologically indistinguishable. Therefore, we designate Bokermannohyla feioi (Napoli & Caramaschi 2004) as a junior synonym of Bokermannohyla nanuzae (Bokermann & Sazima 1973), extending its geographical distribution to the Mantiqueira mountain range. © 2015 Magnolia Press.
