The neotropical rattlesnake Crotalus durissus occurs in South America, where it is generally associated to open areas in the dry diagonal composed of xeric and savanna biomes. Since the 1950’s, however, the species started to be recorded in rainforest biomes. Land-use change, especially the conversion of forests to pasture, remains a widely believe...

We provide an inventory checklist of the amphibians from Parque Nacional da Restinga de Jurubatiba (PNRJ), a sandy coastal environment in southeastern Brazil. As a result of three years of surveys, from August 2013 to June 2016, a total of 36 amphibians species were recorded - one Gymnophiona (Typhlonectidae) and 35 species of five anuran families:...
Article
The coral snake genus Micrurus has non-aggressive behavior, being responsible for only 0.4% of the reports of snakebites in Brazil. However, although rare, accidents are potentially serious due to rapidly evolving respiratory paralysis. In the last few years, there was an abrupt reduction in the number of hospitals receiving antivenom support in Ri...

Stability is an essential feature both to taxonomy and nomenclature. However, zoology is recently being flooded with countless proposals of taxonomic and/or nomenclatural changes, some of which may be considered premature when poorly supported or based upon overestimated hypotheses. We emphasize that the choice of not proposing nomenclatural and/or...

The family Leptotyphlopidae comprises about 120 species allocated in 12 genera including Siagonodon, the latter with four currently recognized species. Here we propose new diagnostic characters for the genus Siagonodon based on the analysis of variation of external morphology and comparisons with related taxa. In order to evaluate the diagnostic ch...
