Asterophryinae

The Asterophryinae are a subfamily of microhylid frogs distributed in an area from the Peninsular Malaysia through the Malay Archipelago to northern Australia. As of 2013, this subfamily contains 274 species in the following 23 genera: The most species-rich genus is Oreophryne (50 species). Four genera are monotypic: Genyophryne, Oninia, Pherohapsis, and Sphenophryne. Microhylid frogs are generally small. A few species such as Callulops robustus and Asterophrys turpicola attain snout-vent lengths (SVL) in excess of 50 mm (2.0 in), whereas frogs in genus Paedophryne are particularly small, and Paedophryne amauensis is the world's smallest known vertebrate, attaining an average body size of only 7.7 mm (0.30 in) (range 7.0–8.0 mm).
