| Diagnosis | Diagnosis: Calotes thailandensis sp. nov. shares the obliquely posteri- or or vertical scale-row orientation on the neck and adjacent supra-axillary area with Calotes irawadi group. It can be separated from other congener- ic species by having combination of the following characters (Tables 4, 5): 1) moderate body size (mean SVL 87.1 mm in male); 2) wide PelvW (mean 13.16 mm and range 11.62–15.07 mm) in male; 3) fewer number of Midbody (mean 42.5) and Dorsal (mean 46.0); 4) Distinct large middorsal crest spine at neck in males (~1.33 × tympanum diameter, range 1.03–1.68 × tympanum diameter) (Table 6); 5). Moderated size of supratympanic spine (~0.6 × tym- panum diameter, range 0.59–0.82 × tympanum diameter) and the anterior supratympanic spine is larger than posterior supratympanic spine (Table 6, Fig. 6A); 6) hindlimb adpressed forward (HAF) reaching between tympanum and eye; 7) usual presence of dark patches on jaw muscles, presence of striping on throat, presence of continuous striping on trunk, and presence of dark stripe (like a collar) on ventral neck of male (Fig. 6B), and rarely appear- ance of dark stripe at ventral trunk. (Prakobkarn et al. 2026) Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data. However, these details, e.g. detailed descriptions (about less than half a page) are available for collaborators and contributors. Please contact us if you need any of this material. |
