Telmatobius gigas (Vellard, 1969)
Class: Amphibia > Order: Anura > Family: Telmatobiidae > Genus: Telmatobius > Species: Telmatobius gigas
Listed as Critically Endangered because its Area of Occupancy is probably less than 10km2, all individuals are in a single sub-population, and the quality of its habitat in the Brazilian Andes is declining.
(1) Snout-vent length of males to 60.4 mm, females to 109 mm; (2) head in lateral profile moderately depressed, with snout sloping; (3) snout slightly subacuminate in dorsal view; (4) lips flared; (5) postcommisural gland absent;
(6) tympanum not visible; a weak supratympanic fold; (7) forelimb of male normal, without humeral spine; (8) nuptial spicules small, closely arranged; nuptial pad covering a large portion of inner palmar tubercle; (9) webbing less than 1/2 of toe lengths; plantar surface smooth; (10) tarsal fold weak, short; (11) dorsal skin moderately rugose with small, round pustules; skin baggy on posterior surface of thighs; (12) dorsum brown or greenish-brown, with a variable pattern of dark blotches or small flecks; (13) venter, throat, and ventral surfaces of limbs beige, with gray mottling; (14) iris golden or bronze, with minute black flecks.
This species is known only from the canyon of the Río Huayllamarca, in Carangas Province, Oruro Department, in the Bolivian Andes, at around 3,965m asl.
It lives in streams in high-elevation puna grassland habitats, where it presumably breeds by larval development.
