Cyrtodactylus khelangensis, a new cave-dwelling Bent-toed Gecko (Squamata: Gekkonidae) from Lampang Province, northern Thailand

Abstract

We describe Cyrtodactylus khelangensis sp. nov. from a limestone cave in Pratu Pha, Mae Mo District, Lampang Province, northern Thailand. It is characterized by a maximal known SVL of 95.3 mm; 16-20 longitudinal rows of dorsal tubercles; a continuous series of 37-40 enlarged femoroprecloacal scales, including six-seven pitted or pore-bearing scales (males) or one or two pitted scales (females) on each femur separated by a diastema from 2-6 pore-bearing precloacal scales (males and females); no precloacal groove nor depression; transversely enlarged subcaudal scales; and four irregular brown dorsal bands between nuchal loop and hind limb insertions.

“…Besides differentiating Cyrtodactylus thathomensis sp. nov. from all congeneric species found within a 500-km radius, its combination of characters presented in the Diagnosis allows to unambiguously separate it from all species found in Bangladesh, Cambodia, Myanmar, Thailand and Vietnam (see, among other references in the literature cited, Bauer, 2003 ; Connette et al, 2017 ; Grismer et al, 2012 ; Le et al, 2016 ; Mahony et al, 2009 ; Mahony, 2009 ; Panitvong et al, 2014 ; Pauwels & Sumontha, 2014 ; Pauwels et al, 2014 , 2016 ; Sumontha et al , 2014 , 2015 ).…”

Systematic revision of the limestone karst-restricted land snail genus Aenigmatoconcha (Eupulmonata: Helicarionidae), with description of a new species

“…The country boasts many unique limestone formations (Naggs et al 2006;Ridd et al 2011;Latinne et al 2013). Thus, Thailand houses many endemic cave-dwelling animals, such as various groups of vertebrates (e.g., Latinne et al 2013;Pauwels et al 2014;Sumontha et al 2017) and invertebrates (e.g., Sedgwick & Schwendinger 1990;Srisonchai et al 2018;Likhitrakarn et al 2020), especially several families of land snails (e.g., Tongkerd et al 2004;Siriboon et al 2014;Dumrongrojwattana & Tanmuangpak 2020;Pholyotha et al 2020bPholyotha et al , 2021Sutcharit et al 2020b). Although the recent studies of karst-associated land snail species in Southeast Asia have flourished, the number of new species discovered has increased every year, supporting that the Thai fauna on limestone karsts, especially land snails, still remains mostly unexplored.…”

Cyrtodactylus kunyai (Squamata: Gekkonidae), a new cave-dwelling Bent-toed Gecko from Loei Province, northeastern Thailand

“…nov. (34) does not overlap with those of C. aequalis (24), C. annandalei (43), C. auribalteatus (38-40), C. bichnganae (30-31), C. brevipalmatus (35-44), C. caovansungi (38-44), C. consobrinus (58-65), C. dumnuii (40), C. huongsonensis (41-48), C. huynhi (43-46), C. kingsadai (39-46), C. russelli (35-41), C. slowinskii (27-32), C. takouensis (39-40) and C. yangbayensis (39-46). From C. khelangensis Pauwels, Sumontha, Panitvong & Varaguttanonda, 2014, which seems to be the closest species in terms of pattern and scalation, C. kunyai sp. nov. is distinguished by the absence of precloacal pores and femoral pits in females (Fig.…”
