From the IUCN Red List Species Account:

 

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 km

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.

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).

Population Trend

Unknown

Major Threats

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.

Taxonomic Notes

Much of the scientific literature uses the name Ptychohyla spinipollex for this species. McCranie and Wilson (1993b) explain the correct usage of the names.
