Scientific Name:	Hyloscirtus charazani
Species Authority:	(Vellard, 1970)
Taxonomic Notes:	This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005). It was rediscovered by J. Aparicio and S. Reichle in 1997 at the type locality.

Assessment Information [top]

Red List Category & Criteria:	Endangered B1ab(iii) ver 3.1
Year Published:	2004
Date Assessed:	2004-04-30
Annotations:	Needs updating
Assessor(s):	Claudia Cortez, Steffen Reichle, Ignacio De la Riva, Jörn Köhler
Reviewer(s):	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification: Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat on the Bolivian Andes.

Geographic Range [top]

Range Description:

This species is found on the eastern slopes of the Andes, and is known from the type locality in Charazani and the nearby Pomasani River, in Huasawaico, Saavedra Province, in the department of La Paz (Aparicio 1999), Bolivia. There is an additional record from near Waleke, in Bautista Saavedra Province, Charazani Canton. The elevation range is 2,700-3,200m asl.

Habitat and Ecology [top]

Habitat and Ecology:	It is an aquatic and terrestrial species, inhabiting streams in the inter-Andean valleys (De la Riva et al. 2000). It is a stream breeder, and the larva is morphologically indistinguishable from larvae of Hyloscirtus armatus sensu lato, exhibiting stream adaptation through a robust body with strong tail musculature, enlarged oral disc, increased number of labial tooth rows, and complete marginal papillae (Lötters et al. 2005).
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The major threat to this species is water pollution: the only known population occurs in a stream used by the local communities living nearby (S. Reichle pers. comm.).

Conservation Actions [top]

Conservation Actions:	The Área Natural de Manejo Integrado Nacional Apolobamba probably protects the population, although the type locality is in a community land-use zone of the reserve. Broad-scale actions are necessary to deal with the threat of water pollution.
