Currently two species of the genus Feihyla are recognised for Borneo. More than a dozen additional species have been described from other parts of Asia. 

Species of Feihyla are arboreal and small in body size. They have slightly forward directed eyes with horizontal elliptical pupils. Both species are unlikely to be confused with any of the other Bornean frog species. See the respective species' pages. Both species produce clutches that are held together only by jelly, not by foam as in Rhacophorus and Polypedates.
