| Remarks | Male urogenital papilla is completely covered by flaplike anus, joined at base; with patch of tightly arranged small odontodes oriented as a swirl covering second, third, and fourth plates of ventral series, lateral to urogenital papilla; with soft-tissue flap along posterior margin of pelvic spine variably developed, when present it is short, restricted to basal onethird to one-half of spine. Female anus tubular, without separate urogenital papilla; size and arrangement of odontodes on plates lateral to anus similar to adjacent plates, without distinct patch of differentially arranged odontodes; pelvic spine without flap of soft tissue on posterior surface (Ref. 84367). |

| Diagnosis |
This species is distinguished from all congeners except H. muzuspi by having preopercle constricted medially (vs. no constriction); canal in preopercle present, semicircular, located posterior to the preopercle constriction (vs. canal absent from preopercle). It differs from H. muzuspi by its wider body, cleithral width 23.7-27.0 (25.7) (vs. 19.1-23.5 (22.2)), a deeper caudal peduncle, caudal-peduncle depth 6.4-9.1 (7.7) (vs. 5.2-6.7 (5.8)), and a larger eye, horizontal eye diameter 19.8-23.3 (21.7) (vs. 13.6-20.7 (18.4)) (Ref. 84367). |
