Differs from all its congeners except P. signicauda by its unusual color pattern consisting of a number of dark saddle like marks on the dorsum, a dark double spot at the caudal fin base and a horizontal stripe and a transverse subdistal band in the caudal fin, and by its total number of 54-56 vertebrae. Can be differentiated from P. signicauda by a more slender body (body depth 13.6-15.4 times in SL vs. 10.8-13.8 times in SL, ratio body depth-body width 1.2-1.5 vs. 1.6-2.2) and a more slender and less laterally compressed caudal peduncle (ratio caudal peduncle depth/width 1.1-1.3 vs. 1.5-2.0). Among other Myanmar Pangio, it is distinguished further from P. fusca and P. pangia by a narrower (caudal peduncle depth 4.8-5.0 % SL vs. 5.9-9.7) and longer caudal peduncle (caudal peduncle length 15.5-16.6 % SL vs. 9.5-12.5), from P. pangia by shorter pectoral fins (5.2-6.5 % SL vs. 8.2-9.6) and a more slender body (body depth 6.5-7.3 % SL vs. 13.5-16.3), from P. fusca by the presence of the pelvic girdle and fins (vs. absence) and the absence of a nasal barbel (vs. presence), and from P. elongata by the position of the pelvic fins (basipterygia at vertebra 29 vs. 33) (Ref. 57993).
