We describe a new species of the rhacophorid genus Philautus from the Truong Son, based on two voucher specimens from montane evergreen and karst forests within Quang Binh Province, central Vietnam. Philautus quyeti sp. n. is distinguished from all other small-sized rhacophorid treefrogs with reduced finger webbing by the combination of the following characters: size relatively small; head longer than wide; vomerine teeth absent; tympanum distinct, rounded, wider than disc of finger III; supratympanic fold indistinct; dermal fringe along outer side of forearm, tibia, tarsus and toe IV absent; skin not lumpy or spinulous, dorsal head, back and upper part of flank rough with small sharp tubercles; dark brown pattern forming an inverse Y, notably a triangular spot between eyes that is separated into two bands that continue posteriorly on the back; throat and margin of throat and chest yellow white with brown marbling.
