Description ( الإنجليزية )

المقدمة من AmphibiaWeb articles
Eleutherodactylus pipilans is a small frog with snout vent length in males of 22.6 - 28.5 mm and in females of 21.1 - 29.4 mm. The body outline is truncate and from above the snout is oval. The eye is large and pupils are round. The tympanum is 36.5 - 54 % diameter of the eye, and vertically oval. The arms are long. Digit pads are slightly expanded or not expanded. Relative front digit length is 3 > 4 > 2 = 1 and has no webbing. The legs are relatively short. The inner metatarsal tubercle is slightly larger to under twice as large as outer tubercle. The skin is smooth to shagreened dorsally and smooth ventrally. Males have a vocal slit (Taylor 1940; Lynch 1970). In life, the background color is dark brown to slightly lighter brown with yellow, orange, light brown, or greenish blotches or spots. The arms are banded. Preserved coloration is light brown with pale blotches (Lynch 1970). There are two subspecies of Eleutherodactylus pipilans, E.p. pipilans and E. p. nebulosus that differ slightly in tympanum size and coloration. Eleutherodactylus p. pipilans tympanum size measured as 40.6 - 54.0 % diameter of eye size, which is larger than E. p. nebulosus’ 36.6 - 47.8 %. Color differences occur in spots, with E. p. pipilans having large light colored blotches or spots, and E. p. nebulosus having small light spots (Lynch 1970).
