Espinas dorsales (total) : 5; Radios blandos dorsales (total) : 13; Espinas anales: 3; Radios blandos anales: 8; Vértebra: 27. This species is disinguished from its congeners by having the following set of characters: striated area extending posteriorly, slightly beyond middle point on the caudal peduncle, its length 66.7% caudal-peduncle length; D V,13; A III,8; gill rakers on first gill arch 6 + 1 + 14 = 21; abdominal scutes 9; lateral-scale rows 58; body height 34.1% SL; pelvic-fin-anal-fin length 30.3% SL; forehead height 2 4.1% SL; pectoral-fin length 18.1% SL; dorsal-fin-anal-fin length 42.6% SL; dorsal-fin length 35.3% SL; postdorsal length 29.6% SL; length between the end
of the anal-fin base to the end of the striated area (A-SA length), 12.4% SL. Colouration: body overall dark-brown, with chest, isthmus, and abdominal scutes uniformly black, and a distinct black vertical line along caudal-fin base (Ref, 129295),
