Hypodactylus is a genus of frogs found in northern South America (from central Peru to Ecuador and Colombia). It is currently placed in family Craugastoridae,[2] although the AmphibiaWeb places it in the family Strabomantidae.[4]
Description
Hypodactylus have head that is narrower than the body. The tympanic membrane is differentiated, but in some species only the tympanic annulus is visible under skin. The dorsum is smooth to weakly tuberculate, whereas the venter is always smooth. The terminal discs on digits are not expanded but usually bear weak circumferential grooves. The terminal phalanges are narrow and T-shaped. Toes III and V are about equal in length (the origin of the name Isodactylus). The smallest species is Hypodactylus adercus where males measure 19 mm (0.75 in) in snout–vent length.[3]
