Cyrtodactylus thirakhupti — GRISMER 2005
|Distribution||S Thailand (Surat Thani)|
Type locality: Southern Thailand, Surat Thani Province, Thachana District, Tham Khao Sonk (= Cave of Sonk Mountain), 9°34’N 99°10’E, collected by Montri Sumontha, 27 June 2003.
|Types||Holotype: CUMZ (Chulalongkorn University Museum of Zoology) R 2003.120|
|Diagnosis||Diagnosis. — Cyrtodactylus thirakhupti can be distinguished from all congeners on the basis of the following combination of characters: body slender, limbs, digits and tail long, dorsal scalation with 14 rows of small keeled tubercles, 37-40 ventral scales across belly between weakly developed ventrolateral folds, no precloacal groove, precloacal pores and femoral pores absent in both sexes, femoral scales enlarged, median subcaudal scales enlarged to form broad transverse plates, and dorsal color pattern consisting of a series of dark-edged light bands. The absence of both precloacal and femoral pores distinguishes C. thirakhupti from all species except most members of the subgenus Geckoella: C. albofasciatus (Boulenger), C. collegalensis (Beddome), C. deccanensis (Günther), C. jeyporensis (Beddome), C. nebulosus (Beddome), and C. yakhuna (Deraniyagala), the Indonesian species C. jellesmae (Boulenger) and C. laevigatus Darevsky, C. paradoxus (Darevsky & Szczerbak) of Vietnam, an undescribed species from Laos (David et al., submitted), and C. sermowaiensis (de Rooij) of New Guinea. It may be distinguished from all Geckoella by its gracile body, long slender tail and long digits, from C. jellesmae, C. sermowaiensis, and the Laotian species by its enlarged series of femoral scales, and from the remaining species by its color pattern (dark-edged, light transverse bands versus dark spots in C. laevigatus and transverse bands interrupted by a narrow vertebral stripe in C. paradoxus). Some specimens of the Thai/ Myanmar species C. oldhami (Theobald) also lack pores (Smith 1935; Taylor 1963, Ulber 1993), but this species may be easily distinguished by its pattern of white spots and stripes. Although C. feae (Boulenger) of Myanmar was originally described as possessing pores, this has subsequently been called into question (see Bauer 2003). Regardless, it also differs markedly in color pattern from C. thirakhupti. Cyrtodactylus derongo Brown & Parker of New Guinea was described on the basis of females only and the condition of precloacal and femoral pores in males is unknown, but this species is much larger (to 112 mm SVL) than C. thirakhupti and differs markedly in color pattern and details of scalation. In general appearance the new species is most similar to the recently described C. sumonthai from Rayong Province, Thailand, which has only two tiny precloacal pores, which may be easily overlooked. However, this species lacks enlarged femoral scales and differs in details of color pattern.|
|Comment||Definition. — A moderately sized Cyrtodactylus, snout-vent length to at least 80 mm; body slender, limbs and digits long, slender, original tail very long; one pair of enlarged postmental scales in broad contact with one another; dorsal scalation with 14 rows of keeled tubercles; approximately 37 ventral scales across belly between weakly-developed ventrolateral folds; no precloacal groove, no precloacal or femoral pores in either sex; eight broad basal lamellae and 12 narrow distal lamellae beneath 4th toe of pes; median subcaudal scales enlarged to form broad transverse plates; dorsal pattern of yellowish bands with very dark brown borders on a lighter brown background.|
Abundance: only known from its original description (Meiri et al. 2017).
|Etymology||Named after Prof. Dr Kumthorn Thirakhupt (Faculty of Science, Chulalongkorn University, Bangkok) in recognition of his contribution to Thai zoology.|
