Asterophryinae is a subfamily of microhylid frogs distributed in an area from the Peninsular Malaysia through the Malay Archipelago to northern Australia.[1]
The following genera are recognised in the subfamily Asterophryinae:[1] The most species-rich genus is Oreophryne (71 species). Two genera are monotypic: Oninia and Siamophryne.[1]
The genera Siamophryne and Vietnamophryne were added to Asterophryinae in 2018.
Microhylid frogs are generally small. A few species such as Callulops robustus and Asterophrys turpicola attain snout-vent lengths (SVL) in excess of 50mm, 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 7.7mm (range 7.0–8.0 mm).[2]
