Adelophryne pachydactyla

Adelophryne pachydactyla is a species of frog in the family Eleutherodactylidae. It is endemic to the coastal area of south-central Bahia state, Brazil.[3][4] Some specimens first identified as A. pachydactyla have later been found to represent a new species, Adelophryne mucronatus; the two species can occur in sympatry.[4] The specific name pachydactyla is derived from Greek pachys (=thick) and daktylos (=finger), referring to the thick, short, swollen fingers of this frog.[2]

Description

Adelophryne pachydactyla was described based on a single specimen, the holotype. It is an adult male measuring 11 mm (0.4 in) in snout–vent length, and with a subgular vocal sac. The head is slightly longer than it is wide. The snout is rounded. The tympanic annulus is incomplete, obscured by skin in its upper parts. There is no supra-tympanic fold and the canthus rostralis is indistinct. The limbs are relatively short. The fingers are short and have swollen, subdigital pads but no discs. The toes have small discs and no webbing. The body is blackish brown with grey spots dorsally and black under. The iris is reddish.[2]

Habitat and conservation

Little is known of this species;[1] the holotype was collected at night on a cacao farm under cacao trees, bananas, and some larger shade trees, found on the ground in the leaf-litter near a small creek.[2] At another site they were collected in terrestrial bromeliads in a forest. The records are from below 800 m (2,600 ft).[1]

The probable threat to this species is habitat loss caused by agriculture, wood plantations, collection of bromeliads, and logging. It occurs in the Serra do Jequitibá Natural Heritage Reserve.[1]

gollark: I don't think this contradicts my point.
gollark: You might think that it would be good to under ethical system #129124124, but human rights are defined by what governments happen to like, and governments sort of kind of vaguely like what the populace likes, and as it turns out most populaces disagree with bodily autonomy, so things.
gollark: I do by divine right, but that's not relevant.
gollark: Why would you think that?
gollark: I don't know of any functioning governments which actually do offer that right.
