Hyloxalus mystax
# Hyloxalus mystax

Hyloxalus mystax is a species of frog in the family Dendrobatidae. It is endemic to Ecuador where it is only known from its type locality on the Cordillera del Cóndor at 1,830 m (6,000 ft) asl. It is a little known species not observed since 1972.

## Description

Males measure 19.5–21.5 mm (0.77–0.85 in) and females 19.2–22.8 mm (0.76–0.90 in) in snout–vent length. They have scattered dark spots on the abdomen. Males have pronounced black stippling on the throat. The male call is a rapid series of chirps.

## Habitat and conservation

The species' natural habitats are cool montane cloud forests. It was fairly common when the type series was collected in 1972; it has not been observed afterwards (there has not been sufficient search effort either). Threats to this species are unknown.
