Diagnosis | Diagnosis: Cyrtodactylus monilatus sp. nov. is assigned to the C. oldhami group on the basis of its recovered phylogenetic position (Fig.1). This species can be distinguished from all other species of the C. oldhami group (sensu Grismer et al. 2021b) by having the following combination of characters: (1) a medium-sized Cyrtodactylus, SVL 53.7–63.3 mm in adult males, 58.6–75.8 mm in adult females; (2) 10–13 supralabial and 8–11 infrala bial scales; (3) 22–34 paravertebral tubercles; (4) 16–21 longitudinal rows of dorsal tubercles; (5) 34–42 ventral scales; (6) 12–16 total subdigital lamellae on the fourth finger; (7) 15–19 total subdigital lamellae on the fourth toe; (8) 30–39 contiguous enlarged femoroprecloacal scales; (9) femoral pores and precloacal pores absent in both sexes; (10) four or five rows of postprecloacal scales; (11) precloacal groove or depression absent; (12) enlarged median subcaudal scales absent; (13) 9–12 dark and light caudal bands encircling the original tail; (14) weak ventrolateral folds present; (15) subconical to slightly prominent trihedral keeled tubercles on body that extend past the base of the tail but no further than 1/3 of anterior portion of tail; (16) top of head bearing large, dark-brown blotches edged in yellow or yellowish white with no light-colored network; (17) 4–7 dorsal body bands composed of paired, paravertebral, dark-brown blotches edged in yellow or yellowish white; and (18) two rows of small, diffuse, yellow or yellowish white spots on flanks. (Yodthong et al. 2021). Additional details (6649 characters) are available for collaborators and contributors. Please contact us for details. |
Comment | Similar species: This species superficially resembles C. zebraicus Taylor, 1962 from southern Thailand. |
Etymology | The specific epithet monilatus is taken from monile (L.) for necklace or string of beads and latus (L.) for flank, in reference to the new species having two rows of small, diffuse, yellow or yellowish white spots on the flanks that resemble a beaded necklace. These spots are an important color pattern difference between the new species and C. zebraicus. We propose “Kanchanaburi Spotted Bent-toed Gecko” for the common English name and “ตุ๊กแกป่าลายจุดเมืองกาญจน์” (Took kae pa lai jud mueang kan) for the common Thai name of the new species. |
