Description
The type series consists of three males and two females measuring Script error: No such module "convert". in snout–vent length; the holotype, an adult male, measures Script error: No such module "convert".. They eyes are inconspicuous. The tympanum is small, about half of the eye diameter. The snout is rounded in dorsal view and truncated in lateral view. The fingers and the toes are long; the fingers are free from webbing but the toes are basally webbed. The dorsum is brown with darker, diffuse blotches. There is a V-shaped inter-ocular band and concave supra-scapular bands. The limbs are cross-banded.[2] The belly is unpigmented apart from some minute gray spots. Dorsal skin is smooth.[2][3]
Habitat and conservation
This species is classified as vulnerable by the IUCN and as "special value" by scientists within Argentina. The population is vulnerable to stochastic forces, fires, and volcanoes. Fast-moving boats on the lake can cause waves that disrupt the frog's breeding sites. Introduction of the American mink to the area may also pose a significant threat: Scientists from the IUCN believe that the frog could become critically endagered due to mink predation if effective measures are not taken.[4]
The type locality is a very humid temperate Nothofagus-dominated forest at Script error: No such module "convert". above sea level. Breeding habitat is unknown but could be small temporary pools. The species is locally common within its restricted range. Isla Grande is a highly protected area and entirely with the limits of the Los Alerces National Park.[4]
