Two new cave-dwelling species of Cyrtodactylus Gray (Squamata: Gekkonidae) from Southwestern Vietnam

Two new cave-dwelling species of Cyrtodactylus from mainland southwestern Vietnam and an offshore island are differentiated from all other congeners in lacking a precloacal groove and precloacal pores, presence of enlarged femoral scales beneath thigh, and in having a color pattern consisting of four or five narrow white bands on the body dorsum and one on the tail. Cyrtodactylus grismeri sp. nov. is reddish brown, has a mean SVL of 87.6 +/- 3.8 mm (n = 9), 18-22 irregular longitudinal rows of weakly-keeled tubercles at midbody between the lateral folds, 33-38 ventral scales between ventrolateral folds, 0-3 enlarged scales beneath thighs, and 20-24 subdigital lamellae under the first toe. Cyrtodactylus eisenmani sp. nov. is chocolate brown, has a mean SVL of 81.3 +/- 5.0 mm (n = 5), 14 irregular longitudinal rows of weakly keeled tubercles at midbody between ventrolateral folds, 44-45 ventral scales between ventrolateral folds at midbody, 4-6 enlarged femoral scales beneath each thigh, and 22-25 subdigital lamellae under the first toe. This discovery increases the total number of Cyrtodactylus found in Vietnam to fifteen.
