Description
editAdult males measure 20–22 mm (0.8–0.9 in) and adult females 20–25 mm (0.8–1.0 in) in snout–vent length. The head is little wider than the body. The snout is sloping, rounded in profile and broadly rounded in dorsal and ventral views. The tympanum is rather inconspicuous and is concealed dorsally and posteriorly by a diffuse supratympanic bulge. The fingers have moderately expanded discs. The toes have weakly to moderately expanded discs some basal webbing between the toes (only distinct between toes II–III). The dorsum is orangish brown, with a usually prominent, wavy-edged, darker brown or grayish brown figure. The face mask is black, continuing and widening behind the eye to become a broad lateral stripe. The arms are pale orange. The upper sides of thighs and shanks are brown (or shanks are brown and thighs are orange), with darker brown crossbands; the posterior thigh surface is either brown with an orange suffusion or overall bright orange.[2]
Habitat and conservation
editAllobates undulatus is diurnal, terrestrial frog found in mossy gallery forest at an elevation of about 1,750 m (5,740 ft) above sea level. It is a common species within its limited range. The threats to this species are unknown. Its range is within the Formaciones de Tepuyes Natural Monument.[1]
