title: A new species of Chirixalus from Vietnam (Anura: Rhacophoridae).
abstract: A new rhacophorid species is described on the basis of two specimens collected from Vu Quang Nature Reserve, Ha Tinh Province, central Vietnam. The species has inner and outer fingers that are not opposable, but in order to avoid taxonomic confusion, it is tentatively assigned to the genus Chirixalus. It is a large Chirixalus, having robust body with warty, grayish dorsum and immaculate ventrum, and lacking large pollex, white granules around anus and on limbs, and dark markings on sides of body. It is most similar to C. eiffingeri and C. idiootocus in external morphology, and much different from the other congeners. Generic definition of the genera Chirixalus and Kurixalus is discussed.
