Abstract We describe a new cave-dwelling Cyrtodactylus from Suan Hin Pha Ngam, Nong Hin District, Loei Province, northeastern Thailand, characterized by a maximal known snout-vent length of 87.9 mm, a banded dorsal pattern with a medially interrupted nuchal loop and four or five brown bands between nuchal loop and hind limb insertions and three bicolored band interspaces between limbs insertions, a dark orangeish iris, a continuous series of enlarged femoro-precloacal scales with 5–6 femoral pores on each side separated by a diastema from 3 precloacal pores in males (no pores in females), 19 irregularly arranged dorsal longitudinal tubercle rows at midbody, 34 ventral scale rows between ventrolateral skin folds, transversely enlarged subcaudal plates, and no precloacal groove. Key words: Cyrtodactylus kunyai sp. nov., taxonomy, limestone cave, Little Kunming
Introduction The limestone hills of Suan Hin Pha Ngam (literally translating as the ‘‘Stone Garden of the Beautiful Cliff’’) are a famous tourist attraction in Loei Province. They were nicknamed ‘’Little Kunming’’ because they remind of the dramatic landscapes found in the southern Chinese Yunnan Province. In the course of fieldwork related to a systematic and phytogeographic review of the Impatiens (Balsaminaceae) of Thailand, two of us (KK and EP) found a population of Cyrtodactylus in a cave of Suan Hin Pha Ngam. They differ from all known species by a combination of color pattern and scalation features, and are consequently described here as a new species.
Material and methods Measurements and meristic counts follow Sumontha et al. (2012) and Pauwels et al. (2013). Paired meristic characters are given left/right. Numbers of supralabial and infralabial scales are counted from the largest scale immediately posterior to the dorsal inflection of the posterior portion of the upper jaw to the rostral and mental scales, respectively. The number of longitudinal rows of body tubercles was counted transversely across the center of the dorsum from one ventrolateral skin fold to the other. The number of longitudinal rows of ventral scales was counted transversely across the center of the abdomen from one ventrolateral skin fold to the other. The numbers of subdigital lamellae beneath the toes were counted from the base of the first phalanx to the claw. The following measurements were taken with a digital caliper to the nearest 0.1 mm: AG: axilla to groin length, taken from the posterior margin of the forelimb at its insertion point on the body to the anterior margin of the hind limb at its Accepted by A.

and underside of fore limbs uniformly whitish, underside of hind limbs darker, except the series of enlarged femoro-precloacal scales, whitish; underside of tail brown (Fig. 3). Variation. Besides the holotype, four other individuals (not preserved) were photographed and examined: a subadult male (Fig. 4), two adult females (Figs 5–7) and a juvenile (Fig. 8). The adults and subadult show a pattern similar to the holotype, with three bicolored band interspaces between limbs insertions, a dark orangeish iris and a medially interrupted nuchal loop. The brown band between the nuchal loop and the brown band above shoulders is variably present (Figs 1–2, 4–8). The juvenile shows a white posterior half of tail, similarly to the subadult male; it also shows a partly interrupted nuchal loop, even if it is less obvious than in adults. The females have a continuous series of enlarged femoro-precloacal scales but lack femoral or precloacal pores or pits (Fig. 6). Distribution and natural history. The species is currently known only from its type locality where it is common. It was found inside small limestone caves and crevices and on nearby outcrops. It is nocturnal. Outside the caves it was found in syntopy with Cyrtodactylus interdigitalis Ulber, Dixonius siamensis (Boulenger), Gehyra fehlmanni (Taylor) and Gekko gecko (Linnaeus) (Gekkonidae). Etymology. The specific epithet, formed in the masculine genitive, honors our friend and colleague Kirati Kunya, curator of the reptile collection of the Nakhonratchasima Zoo, Khorat, for his contributions to the herpetology of Thailand. We suggest the following common names: Took-kai Kirati (Thai), Kunya’s bent-toed gecko (English) and Cyrtodactyle de Kunya (French).
Discussion We compared Cyrtodactylus kunyai sp. nov. with all species known from Cambodia, China, Laos, Myanmar, Thailand and Vietnam (see latest descriptions and intraspecific comparisons in Ulber & Grossmann 1991; Bauer 2002, 2003; Grismer 2008; Mahony 2009; Bauer et al. 2010; Ngo & Chan 2010; Ngo & Pauwels 2010; Nguyen et al. 2010; Chan-ard & Makchai 2011; David et al. 2011; Grismer et al. 2012; Ngo & Grismer 2012; Sumontha et al. 2010; 2012; Nguyen et al. 2013; Pauwels et al. 2013, 2014; Ziegler et al. 2013; Luu et al. 2014; Pauwels & Sumontha 2014; Phung et al. 2014; Schneider et al. 2014). Among the species from these six countries, the phylogenetic relationships of Cyrtodactylus kunyai sp. nov. are likely closer to the other species sharing the possession of precloacal and femoral pores separated by a diastema. From these latter species, Cyrtodactylus kunyai sp. nov. can be readily distinguished by a combination of the following characters: enlarged subcaudals (absent in C. aequalis Bauer, C. huynhi Ngo & Bauer, and C. ziegleri Nazarov, Orlov, Nguyen & Ho); 3 precloacal pores (9 in C. aequalis (female holotype), 11–12 in C. annandalei Bauer, six in C. auribalteatus Sumontha, Panitvong & Deein, ten in C. bichnganae Ngo & Grismer, 7–9 in C. brevipalmatus Smith, nine in C. caovansungi Orlov, Nguyen, Nazarov, Ananjeva & Nguyen, 9–11 in C. consobrinus (Peters), five or six in C. dumnuii Bauer, Kunya, Sumontha, Niyomwan, Pauwels, Chanhome & Kunya, six in C. huongsonensis Luu, Nguyen, Do & Ziegler, 7–9 in C. huynhi and C. kingsadai, 15 in C. russelli Bauer, nine in C. slowinskii Bauer, zero or one in C. thuongae Phung, Van Schingen, Ziegler & Nguyen, 2014, eight or nine in C. tigroides Bauer, Sumontha & Pauwels, 2003, 6-8 in C. yangbayensis Ngo & Chan, 5–8 in C. ziegleri); 19 longitudinal tubercle rows (24 in C. aequalis, 16–18 in C. annandalei, 22–24 in C. auribalteatus, 16–18 in C. bichnganae, 18 in C. brevipalmatus, 16–18 in C. caovansungi, 14–16 in C. huongsonensis, nine or ten in C. huynhi, 22 in C. russelli, nine or ten in C. takouensis, 16–18 in C. thuongae, 13 in C. tigroides, 20–23 in C. yangbayensis, 20–24 in C. ziegleri); a reticulated pattern on head, a medially interrupted nuchal loop, four or five brown bands between nuchal loop and hind limb insertions and three wide bi-colored inter-band spaces between limb insertions (complete nuchal loop, paired dark blotches on dorsum in C. aequalis; no reticulum on head, complete nuchal loop and unicolor band interspaces in C. annandalei; complete nuchal loop in C. auribalteatus; six or seven dark bands between nuchal loop and hind limb insertions in C. bichnganae; blotched dorsal pattern in C. brevipalmatus; two to four very thin, unicolored light band interspaces between limb insertions in C. consobrinus; five or six light band interspaces between limb insertions in C. dumnuii; complete nuchal loop, four light band interspaces between limb insertions in C. huongsonensis; complete nuchal loop, five or six irregular light band interspaces between limb insertions in C. huynhi; complete nuchal loop, four or five light band interspaces between limb insertions in C. kingsadai; irregular banded and blotched pattern in C. russelli; blotched dorsal pattern in C. slowinskii; complete nuchal loop, three or four unicolor yellow band interspaces between limb insertions in C. takouensis; blotched dorsal pattern in C.

thuongae; complete nuchal loop, four bi-colored band interspaces between limb insertions in C. tigroides; five or six irregular dark bands between limb insertions in C. yangbayensis; irregular banded-blotched dorsal pattern in C. ziegleri). In addition, the number of ventral scales of Cyrtodactylus kunyai sp. 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. 6) vs. their presence in C. khelangensis, its marbled caudal bands of the same length as the interspaces in the original tail (vs. immaculate bands two or three times longer than band interspaces in C. khelangensis), its longer dorsum band interspaces relative to the dorsal bands length, its light brown dorsal bands (vs. dark brown in C. khelangensis), the presence of longitudinally elongated dark marks within the band interspaces (absent in C. khelangensis) and a slightly smaller maximal known SVL (87.9 mm, vs. 95.3 mm for C. khelangensis) (see Pauwels et al. 2014). The pace at which cave and karst-dwelling Cyrtodactylus are being discovered and described from Thailand does not seem to decrease, at the contrary (Pauwels & Sumontha 2014). Pursuing the inventory of the Thai cave and karst Cyrtodactylus and analyzing and mitigating their conservation threats has become a conservation priority. Most of these species are micro-endemics, facing a set of specific conservation threats (Ellis & Pauwels 2012; Panitvong et al. 2012), one of them being intensive, uncontrolled tourism – the main potential issue that might threat Cyrtodactylus kunyai sp. nov. for instance. The type locality is indeed a popular touristic site, with an easy access through paths to caves and limestone cliffs. A further development of touristic infrastructure or increase of visitor numbers would probably represent a conservation threat to the species. As far as we know it has not been offered so far in the pet trade.
