fornecido por AmphibiaWeb articles
Gastrotheca abdita belongs to the Gastrotheca marsupiata complex, whose distribution north seems to be impeded by the Huancabamba Depression (ranges and basins of low relief in the Andes of northern Peru and extreme southern Ecuador). Max SVL reaches 35 mm in males, 46.2 in females. Head width is slightly greater than head length. Snout is acuminate when viewed dorsally and bluntly rounded/projecting beyond anterior border of snout in lateral view. Diameter of eye is about equal to eye-nostril distance. Tibia length is 49% SVL. Dorsal skin is smooth to weakly areolate. The first finger is equal in length to second finger. Webbing on foot is variable in length. Dark canthal stripe is absent, tympanum brown, and dorsum uniform brown (80%) or with narrow darker middorsal mark (20%). This species is direct developing. Fingers unwebbed and have a terminal disc whose diameter equals that of the tympanum. Relative length of fingers is 1=2

Gastrotheca abdita

fornecido por wikipedia EN
Gastrotheca abdita is a species of frog in the family Hemiphractidae. It is endemic to Peru and only known from the Cordillera Colán in the Amazonas Region.[3] The specific name abdita is Latin for "exiled" or "removed" and refers to the geographic isolation of the Cordillera Colán.[2] Common name Cordillera Colan marsupial frog has been coined for it.[3]
Description
Males grow to a maximum size of 35 mm (1.4 in) and females to 46 mm (1.8 in) in snout–vent length. The head is slightly wider than it is long. The snout is acuminate in dorsal view and bluntly rounded in profile. The tympanum is brown and distinct, covered by the supra-tympanic fold in its upper part. The fingers have no webbing but bear discs that are much wider than the digits. The toes are about one-fourth webbed and bear discs that are slightly smaller than the finger discs. The dorsum is in most individuals uniform brown, but some have a paler mid-dorsal mark. Skin is smooth dorsally and granular on flanks, belly, and proximal postero-ventral surfaces of the thighs.[2]
Habitat and conservation
Gastrotheca abdita is a terrestrial species occurring in grassy areas, bogs, and the fronds of terrestrial bromeliads at elevations of 2,970–3,330 m (9,740–10,930 ft) asl, above the treeline.[1][2] No major threats to this little-studied species are known. It occurs in the Cordillera de Colán National Sanctuary.[1]
