背的软条 (总数) : 8; 臀鳍软条: 18 - 20; 脊椎骨: 40 - 41. This species is distinguished from its congeners by the size of the humeral spot (2-3 vs. 4-9 horizontal series of scales), number of scale rows below of the lateral line (3-4 vs. 4-8), and total number of pelvic-fin rays (7 vs. 8); differs from most congeners by the number of branched anal-fin rays (18-21 vs. 21-34, and 17 in H. tridens), except H. beni and H. helleri; differs from H. beni and H. helleri by the number of lateral line scales (40-42 vs. 44-53 and 42-44) (Ref. 85819).
