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).

المقدمة من AmphibiaWeb articles
Eleutherodactylus pipilans can be found in Mexico and Guatemala, occurring in southern Mexico as far west as Guerrero along the Sierra Madre del Sur, continuing southeastward through southern Oaxaca and Veracruz, into southern Chiapas and western Guatemala. The species inhabits tropical seasonal forest at elevations from sea. Eleutherodactylus pipilans can be found on or under rocks and under leaf litter (Santos-Barrera et al. 2004).

المقدمة من AmphibiaWeb articles
Eleutherodactylus pipilans is a terrestrial species. Offspring have direct development. Males have distinctive mating call. Large population and a broad habitat range contribute to the species being listed as Least Concern (Santos-Barrera et al. 2004).

Eleutherodactylus pipilans is reported to have a stable population trend by the IUCN. Its only major threat is habitat modification or destruction of tropical seasonal forests (Santos-Barrera et al. 2004).

المقدمة من wikipedia EN
Eleutherodactylus pipilans is a species of frog in the family Eleutherodactylidae. It is found in southern and southeastern Mexico (south-central Guerrero to southern Oaxaca to southern Chiapas) and southwestern Guatemala.[2]
Taxonomy
Two subspecies are sometimes recognized:[2][3]
- Eleutherodactylus pipilans pipilans
- Eleutherodactylus pipilans nebulosus
E. p. nebulosus was first described as a separate species, but became treated as a subspecies by Duellman in 1958.[2][4] Common name nebulous chirping frog refers to this subspecies, whereas common name whistling chirping frog may either refer to the species as a whole or the nominotypical subspecies E. p. pipilans.[2] The subspecies differ in relative tympanum size and coloration.[3][5]
Description
Adult males measure 23–29 mm (0.91–1.14 in) and females 21–29 mm (0.83–1.14 in) in snout–vent length. Skin of the dorsum is smooth or shagreened.[5] The eyes are relatively large. The tympanum is visible and oval in shape. The arms are long while the legs are relatively short.[3] The dorsal background color is dark brown to slightly lighter brown. There are yellow, orange, light brown, or greenish blotches or spots. The limbs are banded. Males have vocal slits.[3][5]
Habitat and conservation
Its natural habitats are tropical seasonal forests[1] at elevations of 100–800 m (330–2,620 ft) above sea level.[2] Individuals are found in a range of microhabitats: on the rocks, on the ground, under rocks and debris,[1] and in a cave.[6] Although locally abundant and tolerating some habitat modification, it is threatened by habitat loss.[1]
