Ananjeva Asian Treefrog
Species Description: Matsui, M. and Orlov, N. 2004. A new species ofChirixalusfrom Vietnam (Anura:Rhacophoridae). Zoological Science: 671-676.
Description : K. ananjevae is a robust, warty frog and ranges from approximately 32 mm to 43 mm in snout-vent length. The skin is free from the skull. The dorsum is tuberculated irregularly with small tubercles that are white at the tip of the snout. The skin on the throat is smooth. The snout projects slightly and is pointed. The pupil is horizontal. The tympanum is distinct. A fold runs from the eye, above the tympanum and ends at the shoulder. The abdomen, and the thighs are coarsely granulated. The tips of the fingers and toes are expanded into discs and webbing on the toes is moderate. Unlike most members of the genus Chirixalus, this species lacks opposable inner and outer fingers, a trait that suggests they be placed in the genus Kurixalus. (Matsui and Orlov 2004).
Coloration in preservation: K. ananjevae has a pinkish grey dorsum, with bifurcated dark dorsal markings and dark cross bars on limbs. The venter is grayish white. Limbs have dark crossbars, but the posterior of the thigh does not have any distinct markings (Matsui and Orlov 2004). The nuptial pads are cream colored and cover the first finger from the base to the subarticular tubercle (Matsui and Orlov 2004; Stuart 2006).
Variation: Females have warts on the posterior margin of the vent, but not on the snout or tarsus like males. The hindlimbs of the female are proportionally shorter than those of the male. The heel of an adpressed hindlimb reaches the middle of the eye in the male and the rear corner of eye in the female (Matsui and Orlov 2004).
