Remarks Males with bony hooks in dorsal, anal, pelvic and pectoral fin rays. Males and females slightly differ in pectoral- and pelvic-fin lengths and body depth and in anal-fin shape, which is slightly concave in males and nearly straight in females. Mature males with gill gland on first gill arch, covering the first branchial filaments (Ref. 85819).

Diagnosis

This species is distinguished from most of its congeners by the number of lateral line scales 44-48 (vs. 39-43 or 48-58). It differs from H. beni, and H. dentatus by the number of branched anal-fin rays (22-27 vs. 15-19 and 28-34, respectively); from H. cairoense by the number of scale rows above lateral line (8-10 vs. 6-7); from H. helleri by the number of scales along anal-fin base scale sheath (17-26 vs. 6-12) and the number of scale rows above lateral line (8-10 vs. 7-8); from H. polyodon by the number of caudal peduncle scales (18-20 vs. 16), head length (22.0-26.0 vs. 20.9-22.9% SL), and upper jaw length (45.2-52.6 vs. 43.7-45.6% HL); from H. raqueliae by the number of predorsal scales (15-19 vs. 10-13) and by the number of cusps of first maxillary tooth (3 vs. 5) (Ref. 85819).
