Sphenophryne thomsoni ( synonym Genyophryne thomsoni ) is a species of frog from the genus Sphenophryne within the subfamily of the Papuan narrow-mouth frogs .
description
The species reaches a length of 32 millimeters. The skin is smooth. The top of the body is patterned reddish brown and black. The temples are whitish. A light line runs down the back from each eye. The back of the thigh and the underside of the tarsus are black. The head is large and severely flattened. The eyes are small and far apart. The pupils are horizontal. The tongue is elongated, with entire margins and freely liftable on the sides. Palatine teeth are present. There is a serrated cross fold in front of the throat. The eardrum is invisible. The fingers are free. The first finger is the shortest. The third finger is much longer than the second and fourth. The medial metatarsal cusp is indistinct. The toes of the base by webbed connected. These do not intervene between the metatarsi of the 4th and 5th toes. The heel has a triangular flap of skin. The tips of the fingers are not widened, those of the toes are slightly widened. There are no precoracoid . The sternum is cartilaginous.
Occurrence
The species occurs only on the southeastern peninsula of New Guinea , where it is mainly found on the north side. Its area extends from the eastern end of the Huon Peninsula to Milne Bay and includes the Louisade Islands and d'Entrecasteaux Islands as well as Woodlark . The vertical distribution ranges from sea level to 1800 meters.
Systematics
The species Sphenophryne thomsoni was first described by George Albert Boulenger in 1890 . The genus Genyophryne was originally established for this species by Boulenger in 1890 , but this genus name was synonymous with Sphenophryne in 2017 .
