Crossodactylodes serranegra

 Abstract  
The bromeligenous genus Crossodactylodes, endemic to the Atlantic Forest domain and the “campo rupestre” ecosystem in Brazil, currently comprises five named species. Three additional putatively new species have already been proposed in a recent study based on mitochondrial and nuclear markers. Here we employ phenotypic data to corroborate the distinctiveness of one of these lineages, and describe it as a new species, from the Espinhaço Mountain Range in the municipality of Itamarandiba, state of Minas Gerais, southeastern Brazil. We also provide information on its natural history and conservation status. The new species is diagnosable from its congeners by a combination of characters, including the presence of vocal slits in adult males, the orange coloration of discs on fingers and toes, and the presence of vomerine odontophores. The new species is the second Crossodactylodes to be reported for the campo rupestre and it was only recorded in a small forest patch composed of low trees, shrubs, mosses, lichens, and a high density of bromeliads.

Pesquisadores da Unesp descrevem nova espécie de sapo
Uso de técnicas de modelagem ambiental e de análise filogenética possibilitou descoberta e descrição do anfíbio. Batizado de C. serranegra, vive apenas no Parque Estadual da Serra Negra. Brasil é o país com maior número de espécies conhecidas de anfíbios.
