Dorsal soft rays (total): 8; Anal soft rays: 7; Vertebrae: 40. This species is readily distinguished from its congeners, except H. beni, by the number of branched anal-fin rays (17 vs. 18-34). It differs from H. beni by the number of lateral line scales (39 vs. 44-53), and by the number of scale rows above and below lateral line (6 and 5 vs. 7-8 and 6-8, respectively); from H. helleri and H. mikrostiktos which have lower branched anal-fin rays (19-23 and 18-21), H. tridens differs by the number of lateral line scales (39 vs. 40-42 and 42-45, respectively).
