We describe a new forest skink species of the genus Sphenomorphus based on specimens from northern Vietnam and from Hainan Island, southern China. The new species is differentiated from the congeners by the combination of the following characters: size small (SVL 35.8-48.8 mm); prefrontals in contact with each other mesially; supralabials seven; primary temporals two; external ear opening present, without lobules, tympanum slightly sunk; midbody scales in 32-34 rows; dorsal scales smooth, paravertebral scales 65-72, not widened; limbs well developed, pentadactyl; 15-19 smooth lamellae under fourth toe; free margins of upper and lower eyelids edged in white; neck, dorsum, and tail base bronze-brown with a discontinuous dark vertebral stripe; upper lateral zone black, interrupted by small light spots from behind the neck. In addition, we provide a review of Vietnamese Sphenomorphus with the first country record of Sphenomorphus mimicus. The generic allocation of Sphenomorphus devorator (allocated to Scincella), Leptoseps tetradactylus (allocated to Sphenomorphus), and Livorimica bacboensis (allocated to Sphenomorphus) is discussed. © 2011 Society for the Study of Amphibians and Reptiles.

We describe a new species of the gekkonid genus Cyrtodactylus from northern Laos, based on four specimens fro Luang Nam Tha Province. Cyrtodactylus wayakonei sp. n. is distinguished from the remaining bent-toed-geckos by the combination of the following characters: snout-vent length up to 90 mm; 7-8 supralabials; 9-10 infralabials; rostrum bearing smooth scales; 34-45 scales between fifth supralabials; dorsal tubercles smooth or slightly keeled; 17-19 dorsal tubercle rows; ventrolateral folds slightly developed, with large tubercles; 31-35 ventrals; 85-98 scales around midbody; 151-163 scales between mental and cloacal slit; 6-8 precloacal pores in both sexes; precloacal groove lacking; enlarged femoral scales absent; femoral pores lacking; subcaudals somewhat enlarged, broadened; tail tubercles flat, smooth; head and dorsum with blotched to reticulated pattern.

We describe a new species of the gekkonid genus Gekko from northern Vietnam on the basis of four specimens from Lang Son and Lao Cai provinces. Gekko canhi sp. n. is distinguished from the remaining congeners by the combination of the following characters: body size moderate (SVL < 100 mm); supralabials 12-14, infralabials 10-13; nares in contact with rostral, internasal single, nasals 3; interorbitals 47-50; dorsal tubercle rows 10-13; scales between mental and cloacal slit 205-229; midbody scales 164-170; subdigital lamellae below first toe 13-16, below fourth toe 14-17; extensive webbing between fingers and toes minimal; tibial tubercles present; precloacal pores 5; postcloacal tubercles 2-3; tail round, not thickened at base; caudal tubercles present; subcaudals enlarged. We also provide new information on the taxonomy and distribution of G. japonicus in Vietnam. Copyright © 2010 Magnolia Press. Source

We describe a new species of Scincella similar to Sphenomorphus tridigitus based on a single specimen from Lang Son Province, northeastern Vietnam. The new species differs from he latter by presence of lower eyelids with undivided opaque window, forelimbs with fi ve digits, and by absence of prefrontals. Scincella apraefrontalis sp. n. isdistinguished from all other species of Scincella and all other Asianlimbreduced lygosomines by a combination of the following characters:no supranasals; no prefrontals; nasal and fi rst supralabial fused; six supralabials; lower eyelid with undivided opaque disc; no externalear openings; 18 midbody scale rows; and pentadactyl limbs.

The genus Oreolalax is reported from Vietnam for the first time and a new species is described based on morphological differences, molecular divergence, and phylogenetic placement Morphologically, the new species is distinguishable from its congeners on the basis of a combination of the following diagnostic characters: size small; tympanum hidden; toes with webbing at base; dorsum with distinct, round, spiny warts; flanks with white, spiny spots; belly and lower surface of limbs smooth, with dark marbling; interorbital region without dark triangular pattern; upper surface of thigh with dark bars; male with black spines present on margin of lower lip, spinal patches on chest small with fine spines, nuptial spines on fingers small, and without vocal sacs In phylogenetic analyses, the new species is unambiguously nested within the genus Oreolalax © 2013 by the American Society of Ichthyologists and Herpetologists.
