Aromobates is a genus endemic to the northern Andes of Colombia and Venezuela. Limited information is available about this genus diversity, current distribution, and taxonomic characterization. Here, we describe three new species of Aromobates from the Andes of Venezuela. We provide the most comprehensive phylogeny of Aromobates to date and taxonomic notes on Aromobates saltuensis Rivero and A. inflexus Rivero. We also discuss the limitations of the current molecular and morphological diagnosis of Aromobates. Finally, we comment on the conservation status and research priorities for this genus. © 2012 Magnolia Press.

A new tuberculated Pristimantis is described from the eastern versant of the Venezuelan Andes. The new species is found in cloud forest at around 1600 masl on the eastern side of the Cordillera de Mérida. It is distinguished from other similar tuberculated species by its round, ill-defined canthus rostralis, ill-defined canthal stripe, and absence of pale spots on the groin and posterior surface of thighs. Pristimantis pleurostriatus is a poorly known species found in cloud forest on the western slopes of the Venezuelan Andes. We redescribe the species based on topotypic specimens. Pristimantis vanadisae is a polychomatic species varying dramatically in pattern; four chromotypes are described. Molecular data are presented which distinguish among tuberculated and other species of Pristimantis in the Cordillera de Merida. Molecular data also support placement of Mucubatrachus and Paramophrynella in Pristimantis. © 2013 Magnolia Press.

A new species of Pristimantis is described from the Venezuelan Andes. The new species is the smallest in its genus known in Venezuela and belongs to the Pristimantis unistrigatus Group. It differs from the rest of Venezuelan Andean congeners in body size (mean male SVL < 21.3 mm, female SVL < 26.3 mm), expanded discs on fingers and toes, absence of dorsolateral folds, and a distinctive call consisting in 2-5 cricket-like short notes. The new species inhabits the southwestern part of the Cordillera de Mérida in Venezuela and the Venezuelan side of the Cordillera Oriental de Colombia, and could be present on the Colombian portion of the cordillera as well. © 2012 Departamento de Ciências Biológicas.
