| 1 | A New Species of Cyrtodactylus(Squamata:Gekkonidae)from the Karst Forests of Daweishan National Nature Reserve,Yunnan,China显示文摘Cyrtodactylus geckos are one of the most speciose and diverse groups of extant lizards known,distributed throughout the Asian and Pacific realms.Using molecular phylogenetic methods and supporting morphological data,we describe a new species of Cyrtodactylus in Daweishan National Nature Reserve,Yunnan Province,China.Cyrtodactylus hekouensis sp.nov.can be morphologically distinguished from its nearby congeners by the following characters:maximum SVL 92.3 mm and TL 98.5 mm;11-12 supralabials;11-12 infralabials;36-57 scale rows between the fifth supralabials;10-13 dorsal tubercles rows;3 postnasals on blunt and smooth front snout;precloacalfemoral pores in a continuous series of 33-39(females with pitted scales)located under vent/cloaca and thighs in both sexes;precloacal groove absent;3/3 postcloacal tubercles;subdigital lamellae under the fourth finger 21 or 22,under the fourth toe 20-23;smooth midbody with smooth venter and tuberculate dorsal scale rows,tubercles from head to tail base;dorsal transverse patterns are generally large,bilaterally symmetrical.The results of the phylogenetic analysis recover specimens of this new species as sister to a clade containing C.wayakonei and C.martini.Uncorrected pairwise intraspecific distances were<1%,and distances between our new species and other Cyrtodactylus species from nearby countries ranged from 14.2%to 26.8%. | YINPENG ZHANG XIAOLONG LIU JUSTIN BERNSTEIN Jian WANG Zhiyong YUAN | 2021 | Asian Herpetological Research2021，12，3： | 0 |
| 2 | Description of two new species of Hemiphyllodactylus(Reptilia: Gekkonidae) from karst landscapes in Yunnan, China, highlights complex conservation needs显示文摘Karst habitats are hotspots of diversity and endemism. Their naturally fragmented distributions across broad geographic landscapes have led to the complex array of smaller evolutionary ecosystems that present unique challenges from a conservation perspective.Comprehensivebiodiversity assessments of karst habitats have revealed that these ecosystems contain an almost unparalleled level of endemism, and many site-restricted species remain undescribed, thus posing considerable challenges for effective conservation management.Small rock-dwelling species, such as geckos, may be particularly prone to such isolation. In this paper, we discuss one such genus, i.e.,Hemiphyllodactylus, and explore its diversity across karst landforms in Yunnan Province, southwestern China. Based on morphological and genetic data, we describe two new species of Hemiphyllodactylus from karst habitats in Simao District and Yanshan County. A phylogenetic tree for Hemiphyllodactylus was constructed using 1?039 base pairs(bp) of the mitochondrial NADH dehydrogenase subunit 2 gene(ND2). The Simao and Yanshan specimens can be distinguished from all other congeners within their respective subclades based on uncorrected genetic pairwise distances greater than 6.3% and 4.3%respectively, as well as significant morphological differences. The discovery and description of these two new species brings the total number of described Hemiphyllodactylus species in China to 14and indicates many more undescribed species from unsurveyed karst regions await discovery.Our findings suggest that karst ecosystems in Yunnan support a higher diversity of Hemiphyllodactylus than previously known.This study also highlights the importance of karst ecosystems as refugia for sitespecific endemic species and the need for heightened conservation efforts. | Ade Prasetyo Agung Ada Chornelia L.Lee Grismer Jesse L.Grismer Evan S.H.Quah Jian-Mei Lu Kyle W.Tomlinson Alice C.Hughes | 2022 | Zoological Research2022，43，5： | 0 |
