Adelophryne is a genus of frogs in the family Eleutherodactylidae.[1][2][3] They are native to northern South America east of the Andes, known roughly from the area corresponding to the Guiana Shield, as well as to the coastal area of Bahia, Brazil. Whether the genus is truly distinct from Phyzelaphryne remains uncertain. Common name shield frogs has been coined for this genus.[2]
Etymology
The generic name is derived from the Greek words adelos, meaning "unseen, unknown, obscure", and phryne for "toad". It refers to the fact that these small frogs were seldom collected until relatively lately.[1]
Description
Adelophryne are small leaf-litter frogs, with adults measuring no more than 17 mm (0.67 in) in snout–vent length.[4] The pupil is oval and horizontally oriented. The tympanum is distinct. The digits are flattened and have asymmetrically pointed, laterally grooved, elongate discs. No webbing is present. The fourth finger is reduced in size. Males have a large, external subgular vocal sac.[1]
