Schistura megalodonis distinguished by having a large processus dentiformes in the upper jaw, a short pre-anus length of 65.4%?66.3% of SL, long paired fins (pectoral: 20.8%?24.2% of SL; pelvic: 17.9%?20.6% of SL), a wide body of 9.7%?11.3% of SL at anal-fin origin, an incomplete lateral line, the absence of an orbital lobe, and a broad and distinct basicaudal bar with forward extensions (Ref. 103219). Description: Dorsal-fin rays iii, 7; anal-fin rays iii, 5; pectoral-fin rays i, 9; pelvic-fin rays i, 6?7; vertebral column with 4+(13?14) abdominal and 19 caudal vertebrae; dorsal fin insertion in larger specimens (4.07?4.17 cm SL) slightly behind pelvic fin origin, in smaller specimens (3.3?3.41 cm SL) slightly in front of pelvic fin origin (Ref. 103219). |
