42D5464CEDB75A42A1BE5E132BD5A4D3.taxon	description	Description of the holotype. Adult male, habitus slender, slightly compressed laterally, SVL 83.5 mm, TAL 206 mm, TAL / SVL 2.47. Rostral scale crescent, width approximately 3.1 times of height, five scales in contact with rostral edge including the first supralabials; nasal octagonal, separated from rostral by one scale, seven scales in contact with nasal on each side; canthus rostralis sharp, composed of 12 enlarged scales on each side; scales on snout irregular in shape and size; an inverted Y-shaped pattern on the middle of the snout; ten supralabials left and eleven right; orbit 7.2 mm in horizontal diameter; distance from anterior edge of orbit to nostril 5.9 mm, and 9.6 mm to tip of rostral scale; tympanum concealed, covered with smooth, slightly imbricate scales, equal in size to adjacent scales; three enlarged scales posterior and horizontal to orbit, keeled and elevated; temporal area with three enlarged, pointing scales. Mental scale triangular, wider than long, slightly narrower than rostral; mental followed by an infralabial on either side and two postmentals in contact with first infralabials; posterior to postmentals are four chin shields on each side that run parallel to infralabials, anterior portion of first chin shield touching first infralabial, remaining portion of first chin shield and following two chin shields separated from infralabials by one scale row; nine infralabials left and ten right. Gular scales anterior to gular pouch small, rounded, imbricate and slightly mucronate; scales of gular pouch slightly keeled, becoming larger toward center. Nuchal crest poorly developed, composed of 29 conical scales. Scales from angle of jaw to shoulder with feebly keeled, imbricate scales, interspersed with three large pointed scales; small oblique curved fold in front of shoulder. Dorsal scales keeled, imbricate, pointing backwards; mid-dorsal scale row strongly keeled and equal in size to bordering dorsal scales, one row of discontinuous, strongly keeled, enlarged, scales net to the vertebral ridge, separated from the mid-dorsal scale row by three scale rows; lateral scales heterogeneous, majority of scales much smaller than dorsals, feebly keeled, imbricate, interspersed with enlarged strongly keeled scales; lateral scales pointing backwards and downwards. Ventral scales larger than lateral scales, approximately equal in size to largest dorsal scales, strongly keeled, imbricate, mucronate, pointing backwards. Limbs slender, covered dorsally with strongly keeled, imbricate, mucronate scales; ventral surface of limbs with smaller feebly keeled, imbricate, scales; relative length of digits: IV> III> II> V> I, relative length of toes: IV> III> V> II> I; 33 / 35 subdigital lamellae under fourth toes. Tail slightly compressed laterally, covered with homogenous, strongly keeled, imbricate, scales.	en	Liu, Shuo, Hou, Mian, Lwin, Ye Htet, Rao, Dingqi (2021): A new species of the genus Ptyctolaemus Peters, 1864 (Squamata, Agamidae) from Sagaing, Myanmar.
