Feihyla vittiger group

This group can be distinguished from the Feihyla palpebralis group by the following suite of morphological characters: small to medium-sized adults (SVL 17–27 mm); snout nearly truncate in lateral view; the first two fingers opposable to the others; webbing absent between fingers, except for a rudiment of web between fingers III and IV at the base; foot webbing moderate, extending up to the second subarticular tubercle on either side of toe IV. A prominent and useful character for differentiating Feihyla vittiger group is the unique colouration of its members: upper arm, loreal, canthal and tympanic regions, lateral surfaces of abdomen, and anterior and posterior parts of thigh non-pigmented (flesh coloured); and a narrow white streak that starts from the snout tip and extends along the lateral surfaces of the head from below the eye up to the groin, clearly separating the dorsal and lateral body colouration ( Fig. 6 ). Geographically, this group is currently restricted to the Southeast Asian islands of Borneo and Java; no reports exist from mainland Asia.

Species included. Feihyla inexpectata ( Matsui, Shimada, and Sudin, 2014) , Feihyla kajau ( Dring, 1983) , Feihyla samkosensis ( Grismer, Thy, Chav, and Holden, 2007) comb. nov., and Feihyla vittiger ( Boulenger, 1897) comb. nov.
