Listed as Least Concern because there is lack of quantitative evidence for ongoing or future declines and the species is distributed throughout much of Central America, with an extent of occurrence (EOO) estimated to be 124,680 km2. It should be noted that there is indication of past declines in part of its range, high prevalence of chytrid infection in parts of its range and habitat fragmentation and loss occurring throughout its range. Therefore, it is recommended that the status of this species be monitored closely. However, threats to the species are spread across a large geographic area. In addition, the species is known from several protected areas.
|Previously published Red List assessments:|
|Range Description:||This species ranges from western Guatemala, through most of Honduras to central Nicaragua, from 620-2,070 m asl. It may also occur in El Salvador, although this needs verification. Its extent of occurrence (EOO) is estimated to be 124,680 km2.|
Native:Guatemala; Honduras; Nicaragua

|Population:||Surveys at Río Cafetal in Sierra de las Minas, Guatemala in 2003 suggested possible declines (Mendelson et al. 2004). However, it is still abundant at various sites where it has been sampled recently in Guatemala and there is lack of quantitative evidence for ongoing declines (C. Vásquez-Almazán pers. comm. 2014). Throughout its range, it occurs primarily along streams in remnant tracts of forest that are surrounded by deforested areas and land use, which has likely rendered the population severely fragmented (C. Vásquez-Almazán pers. comm. 2014).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It is a forest species, living on low vegetation along mountain streams where it breeds, but is tolerant of some habitat disturbance. However, it does require some woody vegetation cover, such as trees along steams in pastureland.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||There are no reports of this species being utilized.|
|Major Threat(s):||The main threats are habitat loss due to expanding agriculture and pasture, forest fires and water pollution. Chytridiomycosis is also a threat. Tadpoles have been found with deformed mouthparts and one was confirmed with chytridiomycosis in Río Cafetal, Baja Verapaz, Guatemala in the Sierra de las Minas, where there has been an observed dramatic population decline (although the species is still present at this site) (Mendelson et al. 2004), while an additional positive chytrid test (57.5% prevalence) was confirmed for Parque Nacional Cusuco in Honduras (Kolby et al. 2010). Although this species is widely distributed across Mesoamerica, its fragmented distribution leaves populations highly vulnerable to local extirpation (J.E. Kolby pers. comm. 2008).|
|Conservation Actions:||It occurs in a number of protected areas throughout its range, including Biotopo del Quetzal, Sierra Caral, Parque Nacional Cusuco and Parque Nacional Cerro Azul. However, given fragmentation of forests throughout its range, additional habitat protection would be important. In view of the threat of chytridiomycosis, the status of this species should be closely monitored.|
