ZMKU R 00827, ZMKU R 00829–00831 (four adult males), ZMKU R 00832–00835 (four adult fe- males), THNHM 28694–28695 (two adult males) and THNHM 28696–28697 (two adult females), same data as holotype. |
| Diagnosis | Diagnosis: Cnemaspis lineatubercularis sp. nov. can be distinguished from all other Cnemaspis by having the following combination of characters: (1) maximum SVL of 40.6 mm (mean 38.8 ± SD 1.4, N = 12) in adult males and maximum SVL of 41.8 mm (mean 39.5 ± SD 1.9, N = 7) in adult females; (2) 8–9 supralabial and infralabial scales; (3) gular, pectoral, abdominal, and subcaudal scales keeled; (4) rostral, interorbitals, supercilium, palmar scales, and ventral scales of brachia smooth; (5) 5–6 small, subconical spine-like tubercles present on flanks (6) 19–21 paravertebral tubercles linearly arranged; (7) 27–29 subdigital lamellae under the 4th toe; (8) 4–7 pore-bearing precloacal scales, pores rounded, arranged in chevron shape and separated in males; (9) one postcloacal tubercle each side in males; (10) ventrolateral caudal tubercles anteriorly present; (11) caudal tubercles restricted to a single paravertebral row on each side; (12) single median row of subcaudal scales keeled and lacking enlarged median row; and (13) gular region, abdomen, limbs and subcaudal region yellowish only in males. These differences are summarized among geographically close congeners in the siamensis group (Table 5). |
| Comment | Habitat: Specimens were found only along granitic rocky streams of Wang Mai Pak Waterfall. The rocky boulder microhabitats of this species are dry with cool surface temperatures (24.8–26.7 °C, 73.2–86.1% relative hu- midity). When disturbed, some individuals retreated deeper into rock crevices, cracks, more shaded areas or beneath rock boulders (Ampai et al.2020). |
| Etymology | The specific epithet lineatubercularis is taken from linea (Lat. for line) and tubercularis (Lat. for having tubercles), in reference to the new species having para-vertebral tubercles linearly arranged. |
