Description

The adult male frog measures about 16.8 mm in snout-vent length and the adult female frog is 12.4–18.1 mm long. There are two spots on the gular-pectoral area. The adult female frog has a white belly.^[3]

Habitat

Scientists observed this frog in a cloud forest 2987 meters above sea level.^[1]

Reproduction

Scientists have not observed this frog's mode of reproduction, but they infer that the larvae swim in streams.^[1]

Threats

The IUCN classifies this frog as critically endangered and estimates the current population at fewer than 249 individuals. Principal threats are habitat loss in favor of agriculture and logging. Introduced trout can also hurt this frog. Scientists have observed the fungal disease chytridiomycosis on other frogs in Hyloxalus, so they believe the disease may also affect this species.^[1]
