Abstract
We describe a new species of the Cyrtodactylus irregularis complex from Ba Den Mountain, Tay Ninh Province, southern Vietnam based on molecular divergence and morphological differences. Cyrtodactylus tayninhensis sp. nov. is distinguished from the remaining congeners of the C. irregularis group by having the unique combination of: size medium (SVL 73.4–80 mm); dorsal tubercles in 13 or 14 irregular rows; 36–39 ventral scale rows; enlarged femoral scales absent; precloacal pores absent in females, 4–6 in males, in a continuous row; femoral pores absent; postcloacal spurs two or three on each side; lamellae under toe IV 16–18; a U-shaped continuous neckband, dorsal pattern between limb insertions consisting of two or three irregular yellow-brown bands and tail with 8–10 thin light bands (with two bands near vent light brown, others white); the absence of transversely enlarged median subcaudal scales. In terms of phylogenetic analyses, the new species is recovered as a member of the Cyrtodactylus irregularis species group without any clear sister taxon. Genetically, Cyrtodactylus tayninhensis sp. nov. is separated from the remaining taxa of the Cyrtodactylus irregularis group by a minimum of 13.13% and 16.09% based on fragments of the mitochondrial COI and ND2 genes, respectively.
