caption_attribution_description: English: Maximum likelihood phylogeny of Paedophryne and asterophryine frogs. Colors of branches correspond to maximum male SVL (Paedophryne) or average SVL within each clade on a logarithmic scale. Circles above branches correspond to posterior probabilities: black: &gt;0.95; grey: 0.85–0.95; white: 0.5–0.85. Circles below branches correspond to maximum likelihood bootstrap support: black: &gt;95%; grey: 75–95%; white: 50–75%. doi:[10.1371/journal.pone.0029797.g003]
context_page_description: Asterophryinae is a subfamily of microhylid frogs distributed in an area from the Peninsular Malaysia through the Malay Archipelago to northern Australia.
context_section_description: 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).
