| Diagnosis | Diagnosis: Cnemaspis lineogularis is distinguished from all other species of Cnemaspis in the chanthaburiensis group by the combination of the following morphological and color pattern characters: maximum SVL 38 mm; nine supralabials; eight infralabials; ventral scales smooth; no precloacal pores; 13 paravertebral tubercles linearly arranged; no tubercles on the lower flanks; lateral caudal furrows present; no caudal tubercles in the lateral furrows; ventrolateral caudal tubercles anteriorly; caudal tubercles not encircling tail; subcaudals smooth bearing a single median row of enlarged smooth scales; lateral caudal tubercle row absent; shield-like subtibial scales absent; one post cloacal tubercle in males; no enlarged femoral or submetatarsal scales; enlarged femoral scales; subtibials smooth; 27–29 subdigital fourth toe lamellae; sexually dimorphic for dorsal color pattern; gular region yellow-orange, thick, black lineate markings in males, absent in females; subcaudal region whitish. Comparisons. Cnemaspis lineogularis sp. nov. can be differentiated for all other species in the chanthaburiensis group based on the following morphological and color pattern characteristics (see Tables 5 and 6 for additional comparisons). Cnemaspis lineogularis sp. nov. differs from C. chanataburiensis, C. neangthyi, C. laoensis, C. aurantiacopes, C. caudanivea, C. nuicamensis, and C. tucdupensis by having a smaller maximum SVL (38 mm vs. 42.2 mm, 54.0 mm, 40.9 mm, 58.4 mm, 47.2 mm, 48.2 mm, and 51.0 mm, respectively), by having less paravertebral tubercles (13 vs. 21–25, 20–26, 22, 23–31, 20–24, 16–21, and 16–22 respectively), and by having enlarged femoral scales. Cnemaspis lineogularis sp. nov. is further differentiated from C. neangthyi by having less supralabial scales (9 vs. 11–13). Cnemaspis lineogularis sp. nov. differs from C. neangthyi by having less infralabial scales (8 vs. 10–12) and from C. nuicamensis by having more infralabial scales (8 vs. 6–7). It is further differentiated from C. chanthaburiensis, C. neangthyi, C. aurantiacopes, C. caudanivea, and C. nuicamensis by lacking precloacal pores. From C. loaensis, C. lineogularis sp. nov. differs by having linearly arranged tubercles versus randomly arranged tubercles. Cnemaspis lineogularis sp. nov. differs from C. chanthaburiensis, C. neangthyi, C. laoensis, C. aurantiacopes, C. nuicamensis, and C. tucdupensis by lacking tubercles on the lower flanks. Cnemaspis lineogularis sp. nov. differs from C. chanthaburiensis, C. neangthyi, C. laoensis, by lacking caudal tubercles in the lateral furrow. Cnemaspis lineogularis sp. nov. has ventrolateral caudal tubercles anteriorly which separates it from C. chanthaburiensis and C. laoensis which lack this character. Cnemaspis lineogularis sp. nov. differs from C. loaensis, C. caudanivea, C. nuicamensis, and C. tucdupensis by the presence of a lateral caudal tubercle row. From C. chanthaburiensis, C. laoensis, C. caudanivea, and C. tucdupensis, C. lineogularis sp. nov. differs by having an enlarged median subcaudal scale row. C. lineogularis sp. nov. differs from C. laoensis and C. nuicamensies by having one postcloacal tubercle in males versus 2,3 and 2–4 respectively. C. lineogularis sp. nov. is further differentiated from C. caudanivea by lacking shield-like subtibial scales. Cnemaspis lineogularis sp. nov. differs from C. neangthyi, C. laoensis, and C. aurantiacopes by lacking keeled subtibial scales. Cnemaspis lineogularis sp. nov. differs from C. aurantiacopes and C. tucdupensis by lacking an enlarged submetatarsal scale on the 1st toe. Cnemaspis lineogularis sp. nov. is further differentiated from from C. neangthyi by having more 4th toe lamellae (27–29 vs. 22–25). Cnemaspis lineogularis sp. nov. is further differentiated from all other species in the chanthaburiensis group based on squamation and color pattern characteristics (Tables 5 and 6). |
| Comment | Behavior: diurnal Sympatry: Cyrtodactylus somroiyot Abundance: only known from its original description (Meiri et al. 2017). |
| Etymology | The specific epithet lineogularis is derived from the Latin adjective linues for the word ‘‘line’’ and the nominative form of the Latin word gulare meaning ‘‘throat’’ and is in reference to the multiple dark gular lines present in the males of this species. |
