Can be further distinguished from H. bongan in having body depth at anus 12.2-13.6% SL (vs. 9.5-12.9), and from H. divaricatus in having maximum height of adipose fin 4.1-6.0 times in length of base (vs. 1.9-3.2) and eye diameter 17-19% HL (vs. 11-17). Differs further differs from H. gracilis in having caudal peduncle depth 7.3-8.1% SL (vs. 6.2-7.6) and vertebrae 49-50 (vs. 50-52) and H. planiceps in having interorbital distance 30-32% HL (vs. 32-37) and vertebrae 49-50 (vs. 47-49) (Ref. 93057).
