Paratopotype. BYU 62537 adult female paratype bears all the same collection and locality information as the holotype.
|Diagnosis||Diagnosis: Cnemaspis phangngaensis sp. nov. is distinguished from all other species of Cnemaspis in the siamensis group by the combination of the following morphological and color pattern characteristics: maximum SVL 42 mm; 10 supralabials; 10 infralabials; ventral scales keeled; four continuous precloacal scales bearing a single round pore in males; 22 paravertebral tubercles linearly arranged; no tubercles on the lower flanks; lateral caudal furrows present; no caudal tubercles in the lateral furrows; lateral caudal tubercle row present; ventrolateral caudal tubercles anteriorly; caudal tubercles not encircling tail; caudal tubercles restricted to a single paravertebral row; subcaudals keeled bearing a single median row of enlarged keeled scales; two post cloacal tubercle in males; no enlarged femoral, tibial, or sub metatarsal scales; subtibials keeled; no enlarged median subcaudal scale row; no submetatarsal scale on first toe; 29 subdigital fourth toe lamellae; no enlarged median subcaudal scale row; dorsal and ventral color pattern sexually dimorphic; yellow or white bars present on flanks; prescapular marking present; anterior gular region dark yellowish, no dark lineate markings in males or females, and no mid-gular marking; posterior gular region and pectoral region whitish in males; abdomen yellow; subcaudal region yellow.|
Comparisons. The phylogenetic analysis recovers the chanardi group and C. phangngaensis sp. nov. as the sister species to a clade containing C. omari and C. roticani (Fig. 2). This relationship is further supported by the following derived morphological characters (sensu Grismer et al., 2014d), prescapular crescent present, yellow abdomen, yellow ventral surfaces of the hind limbs and tail being yellow and numerous other morphological and color pattern characteristics (Tables 5 and 8). C. phangngaensis sp. nov. differs from C. chanardi, C. omari, and C. roticanai by having; more infralabial scales (10 vs. 6–8, 7,8, and 7,8, respectively); continuous precloacal pores; paravertebral tubercles linearly arranged; lacking tubercles on the lower flank; ventrolateral caudal tubercles anteriorly; caudal tubercles restricted to a single paraveterbral row on each side; a single median row of keeled subcaudals. Cnemaspis phangngaensis sp. nov. is further differentiated from C. chanardi and C. omari by having a larger maximum SVL (42 mm vs. 40.1 mm and 41.3 mm, respectively). Cnemaspis phangngaensis sp. nov. differs from C. omari, and roticani by having more supralabial scales (10 vs. 8,9 and 8,9, respectively). C. phangngaensis sp. nov. differs from C. chanardi by having fewer precloacal pores (4 vs. 6–8). Cnemaspis phangngaensis sp. nov. differs from C. roticani by having fewer paravertebral tubercles (22 vs. 25–27). From C. roticanai, C. phangngaensis sp. nov. differs by lacking caudal tubercles in the lateral furrow and by having a lateral caudal tubercle row present. Cnemaspis phangngaensis sp. nov. differs from C. omari by lacking caudal tubercles encircling the tail and by having more lamellae under the 4th toe (29 vs. 25–28). Cnemaspis phangngaensis sp. nov. is further differentiated from C. chanardi by lacking an enlarged median subcaudal scale row. From C. chanardi and C. omari, C. phangngaensis differs by have two postcloacal tubercles in males versus one. Cnemaspis phangngaensis is further differentiated from all other species in the siamensis group based on squamation and color pattern characteristics (Tables 5 and 8).
Sympatry: Cyrtodactylus lekaguli (which may predate on Cnemaspis phangngaensis).
Abundance: only known from its original description (Meiri et al. 2017).
|Etymology||The specific epithet phangngaensis is a noun in apposition to the type locality where this species is found.|
