The most species-rich genus is Oreophryne (50 species). Four genera are monotypic: Genyophryne, Oninia, Pherohapsis, and Sphenophryne.[2]

Body size

Phylogeny and evolution of body size in Asterophryinae. Colours of branches correspond to maximum male snout-vent length (Paedophryne) or average snout-vent length within each clade on a logarithmic scale.[4]

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).[4]
