Colostethus awa

Hyloxalus awa is a species of frog in the Dendrobatidae family. It is endemic to Ecuador and known from the western Andean slopes and the western Pacific lowlands.[3]


Males measure 16–22 mm (0.63–0.87 in) and females 19–26 mm (0.75–1.02 in) in snout–vent length. Dorsum is reddish brown with diffuse dark marks. Flanks are dark gray.[2][4]


The male call is a trill of about 3–5 seconds in duration, emitted at a rate of six calls per minute.[2] Males are territorial and aggressive towards other males. Under laboratory conditions, mating takes place in morning and clutch size is 4 to 21 eggs.[4] Eggs are laid on leaf-litter or low vegetation; the adults carry the tadpoles on their back to nearby streams where they complete their development.[1]

Habitat and conservation[edit]

Natural habitats of Hyloxalus awa are humid sub-montane tropical forest. It is threatened by habitat loss due to agriculture (both crops and livestock), logging, and agricultural pollution.[1]
