Grismer LL, Aowphol A, Grismer JL, Aksornneam A, Quah ESH, Murdoch ML, Gregory JJ, Nguyen E, Kaatz A, Bringsøe H, Rujirawan A. A new species of the Cyrtodactyluschauquangensis group (Squamata, Gekkonidae) from the borderlands of extreme northern Thailand. Zookeys 2024; 1203:211-238. [PMID: 38855793 PMCID: PMC11161685 DOI: 10.3897/zookeys.1203.122758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Accepted: 05/03/2024] [Indexed: 06/11/2024] Open
Abstract
Phylogenetic and morphological analyses delimit and diagnose, respectively, a new population of a karst-dwelling Cyrtodactylus from extreme northern Thailand. The new species, Cyrtodactylusphamiensis sp. nov., of the chauquangensis group inhabits karst caves and outcroppings and karst vegetation in the vicinity of Pha Mi Village in Chiang Rai Province, Thailand. Within the chauquangensis group, Cyrtodactylusphamiensis sp. nov. is the earliest diverging species of a strongly supported clade composed of the granite-dwelling C.doisuthep and the karst-dwelling sister species Cyrtodactylus sp. 6 and C.erythrops. The nearly continuous karstic habitat between the type locality of Cyrtodactylusphamiensis sp. nov. and its close relatives Cyrtodactylus sp. 6 and C.erythrops, extends for approximately 200 km along the border region of Thailand and the eastern limit of the Shan Plateau of Myanmar. Further exploration of this region, especially the entire eastern ~ 95% of the Shan Plateau, will undoubtably recover new populations whose species status will need evaluation. As in all other countries of Indochina and northern Sundaland, the continual discovery of new karst-dwelling populations of Cyrtodactylus shows no signs of tapering off, even in relatively well-collected areas. This only highlights the conservation priority that these unique karstic landscapes still lack on a large scale across all of Asia.

Tran TT, Do QH, Pham CT, Phan TQ, Ngo HT, Le MD, Ziegler T, Nguyen TQ. A new species of the Cyrtodactyluschauquangensis species group (Squamata, Gekkonidae) from Lao Cai Province, Vietnam. Zookeys 2024; 1192:83-102. [PMID: 38419746 PMCID: PMC10897834 DOI: 10.3897/zookeys.1192.117135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 02/01/2024] [Indexed: 03/02/2024] Open
Abstract
We describe a new species of the genus Cyrtodactylus based on five adult specimens from Bac Ha District, Lao Cai Province, northern Vietnam. Cyrtodactyluslucisp. nov. is distinguished from the remaining Indochinese bent-toed geckos by a combination of the following morphological characteristics: medium size (SVL up to 89.5 mm); dorsal tubercles in 17-19 irregular transverse rows; ventral scales in 32-34 longitudinal rows at midbody; precloacal pores present in both sexes, 9 or 10 in males, 8 or 9 in females; 12-15 enlarged femoral scales on each thigh; femoral pores 9-12 in males, 5-10 in females; postcloacal tubercles 2-4; lamellae under toe IV 21-23; dorsal pattern consisting of 5 or 6 irregular dark bands, a thin neckband without V-shape or triangle shape in the middle, top of head with dark brown blotches; subcaudal scales transversely enlarged. Molecular phylogenetic analyses recovered the new species as the sister taxon to C.gulinqingensis from Yunnan Province, China, with strong support from all analyses and the two taxa are separated by approximately 8.87-9.22% genetic divergence based on a fragment of the mitochondrial ND2 gene. This is the first representative of Cyrtodactylus known from Lao Cai Province.

Abstract
A new species of Cyrtodactylus is described from Vairengte town, situated in the Kolasib District of Mizoram State, north-eastern India. The new species is found to be a member of Indo-Burman Cyrtodactylus khasiensis clade based on ND2 gene sequences and morphological parameters, such as number of precloacal pores, mid-ventral scale rows, paravertebral tubercles on the trunk, dorsal tubercle rows, subdigital lamellae on pes and subcaudal scalation, making it the sixth endemic Cyrtodactylus from Mizoram and twenty second from north-east India. Moreover, phylogenetic evidence suggests the new species to be sister to the recently described C. aaronbaueri, and morphological analyses also reveal marginal separation between the two species based on the PCA of infralabials, lamellae on fingers and toes, paravertebral tubercles on the trunk, and dorsal tubercle rows.
