Synonym/s:	Colostethus shuar Duellman and Simmons, 1988

Assessment Information [top]

Red List Category & Criteria:	Near Threatened ver 3.1
Year Published:	2004
Assessor/s:	Luis A. Coloma, Santiago Ron, Taran Grant
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Contributor/s:
Justification: Listed as Near Threatened since although its Extent of Occurrence is less than 20,000 km2 and its habitat is declining, thus making the species close to qualifying for Vulnerable, it occurs in more than ten locations.

Geographic Range [top]

Range Description:	This species occurs on the eastern slopes of the Andes in Napo, Tungurahua, Morona Santiago and Zamora Chinchipe Provinces, Ecuador, between 1,272 and 2,370m asl.

Population [top]

Population:	It was at least formerly abundant, judging by the large series collected through 1984 in the Kansas Museum. It was common in a stream near Loma El Trigal, on the road between Loja y Zamora, in 1987.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It lives in premontane and cloud forest (Coloma 1995) but its tolerance of disturbed habitats is unknown. Reproduction probably occurs by females laying eggs on the ground, with the males bringing the larvae to streams for them to complete their development. In north-eastern Ecuador it occurs in sympatry with Colostethus bocagei, C. fuliginosus, C. kingsburyi, C. pulchellus and Minyobates abditus near Volcán Reventador. In south-eastern Ecuador the species occurs with C. kingsburyi, and C. pulchellus at the Pastaza trench, and further south with C. exasperatus, C. mystax and C. peculiaris.
Systems:	Terrestrial; Freshwater
