Andinobates altobueyensis

The holotype, an adult female, measured 17 mm (0.67 in) in snout–vent length. The adult male in the type series measured 15.5 mm (0.61 in) in snout–vent length; the other specimens were juveniles or not measured. These frogs are entirely yellow of various shades (yellow, greenish yellow, or golden); some individuals have small black spots on the dorsum, others also on the venter. The skin of back is slightly granular. The tympanum is round and has its postero-dorsal part concealed. Both fingers and toes lack fringes and webbing.[2]

Its natural habitat is humid pre-montane forest at elevations of 980–1,070 m (3,220–3,510 ft) above sea level.[1][4] It lives on the ground and in bromeliads.[1] The tadpoles probably live in aroid leaf axils—almost all axils near the summit of Alto del Buey contained a tadpole, but it is not certain that they were this species, as opposed to Andinobates minutus.[2]

This frog has a very restricted range, and there is risk of habitat loss caused by smallholder agricultural activities, logging, and human settlement.[1]
