|Taxonomic Notes:||In the genus Nymphargus according to Cisneros-Heredia and McDiarmid (2007). Nymphargus mixomaculatus is diagnosed from other similar glassfrogs by a combination of morphological features and colour patterns (Guayasamin et al. 2006).|
|Red List Category & Criteria:||Critically Endangered B1ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Lehr, E. & Guayasamin, J.|
Listed as Critically Endangered because of its extent of occurrence (EOO) of 10 km2, it occurs in one threat-defined location, and there is a continuing decline in the area and quality of its habitat in the Cordillera de Carpish.
|Previously published Red List assessments:|
|Range Description:||This species is known from Cordillera de Carpish, vicinity of Caserío Carpish de Mayobamba, Province of Huánuco, Huánuco Region, Peru (Guayasamin et al. 2006). It occurs 2,625–2,750 m asl, the extent of occurrence (EOO) of its known range is 10 km2, and all individuals are considered to occur in a single threat-defined location. The species could have a restricted range, although this has to be tested with further field work (J.M. Guayasamin pers. comm. 2008).|

|Population:||The species is known from the type series, comprised of six specimens. There have not been recent surveys to the type locality since the species was described in 2006 (E. Lehr pers. comm. April 2017). 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).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||The species inhabits montane forests within the Selva Alta or Yungas ecoregion. At night, individuals of were found in bushes along a small fast-moving stream. The species breeds by larval development in permanent water (J.M. Guayasamin pers. comm. 2008).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||The Cordillera de Carpish is not protected under Peruvian law, making it susceptible to deforestation for agriculture and timber extraction (Chávez et al. 2015). At the type locality there are some agriculture activities including livestock, and as this species is associated with small creeks these activities may negatively affect this species (E. Lehr pers. comm. April 2017). Furthermore, an interstate road which crosses Cordillera de Carpish (at both sides of Chinchao river) and the developing of mining concessions in the area are additional threats (Chávez et al. 2015).|
It is not known from any protected areas.
As the Cordillera de Carpish is known for its high levels of endemism, legal protection of the Cordillera de Carpish is recommended.
More information is needed on this species' distribution, population status, ecology, and threats.
