Oxydactyla is a genus of microhylid frogs endemic to New Guinea[1][2] and occur in montane areas, at elevations of 1,800–4,000 m (5,900–13,100 ft) above sea level.[2]

Taxonomy

The genus was removed from the synonymy of Sphenophryne by Richard Zweifel in 2000.[1][2] In 2016, molecular data showed that Oxydactyla alpestris belongs to Copiula. Whether the remaining Oxydactyla are a monophyletic group remains unknown.[3]

Description

Oxydactyla are small, short-legged frogs. The maximum size is 32 mm (1.3 in) snout–vent length. Males can mature as small as 19 mm (0.75 in) SVL. They lack finger discs; finger tips are usually narrow and rounded, at most slightly flattened.[2]

Species

There are at present four species in this genus:[1]

Binomial Name and AuthorCommon Name
Oxydactyla brevicrus Van Kampen, 1913 Hellwig Land Frog
Oxydactyla coggeri Zweifel, 2000
Oxydactyla crassa (Zweifel, 1956)
Oxydactyla stenodactyla Zweifel, 2000

The AmphibiaWeb[4] also includes Oxydactyla alpestris that Peloso and colleagues moved to Copiula in 2016.[3]
