Metaphrynella is a small genus of microhylid frogs from the southern Malay Peninsula and Borneo. They are sometimes known as the Borneo treefrogs[1] or tree hole frogs. The common name refers to the microhabitat of these frogs: males call from tree holes and tadpoles develop in the water contained in those holes.[2]
Metaphrynella are small, arboreal frogs that have plump bodies and adhesive finger and toe tips.[2]
Metaphrynella may be paraphyletic, as molecular data[3] suggest that Phrynella is phylogenetically imbedded within it. Another study suggests that its closest relatives are Kaloula, Uperodon, and Ramanella.[1] A molecular phylogenetic study by De Sá et al. (2012)[3] shows Kaloula to be a sister clade of Metaphrynella.
