Range Description

Cordillera de Carpish, vicinity of Caserío Carpish de Mayobamba (09 43' 50" S, 76 06' 46" W, 2625 masl, and 09 43' 14" S, 76 06' 53" W; 2735–2750 m), Province of Huánuco, Department of Huánuco, Peru (Guayasamin et al., 2006).

Habitat and Ecology

The species inhabits montane forests within the Selva Alta or Yungas Ecoregion, in an area where humans have had little impact. At night, individuals of Nymphargus mixomaculatus were found syntopically with Gastrotheca stictopleura in bushes along a small fast-moving stream. Other sympatric anurans include Rhinella chavin, Pristimantis sp., Phrynopus carpish, Phrynopus dagmarae, and Phrynopus kauneorum (Guayasamin et al., 2006).

The species breeds in permanent water (J.M. Guayasamin, pers. comm. 2008).


The species is known from the type series, comprised of six specimens. It is possible that the species may be locally abundant, but further field work is needed to verify this (J.M. Guayasamin, pers. comm. 2008).

Population Trend


Major Threats

The species could have a restricted range, although this has to be tested with further field work (J.M. Guayasamin, pers. comm. 2008).

Conservation Actions

No conservation measures are known for this species.
