A new species of marsupial frog (Anura; Gastrotheca) from the Cordillera de Colán in northeastern Peru

We describe a new species of marsupial frog, genus Gastrotheca , using morphological characters and molecular data as lines evidence. The was discovered in the páramo ecotone between humid montane forest Cordillera de Colán, at elevations 3136 3179 m a.s.l., northeastern Peru. is distinguished from all its congeners by combination following characters: coarsely granular skin on dorsum, green dorsal coloration without pattern, finger I shorter than II, turquoise iris, venter blotches, flecks or dots. Furthermore, we include detailed osteological description based Micro-CT scanning. Based our phylogenetic analyses, belongs to marsupiata group, sister G. oresbios closely related psychrophila spectabilis stictopleura one undescribed species. Additionally, test for presence fungal pathogen Batrachochytrium dendrobatidis ( Bd ). No infection detected gemma sp. nov. specimens but prevalence among syntopic frogs.
