Etymology: Hypoptopoma: Greek, hypo = under + Greek, optoma, opsomai = to look at, to watch + Greek, poma = cover, operculum (Ref. 45335); brevirostratum: Name from Latin 'brevis' for short and 'rostrum' for snout, referring to its short head.

Morphology | Morphometrics
Vertebrae: 27. 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).
