Classification The systematic placement is tentative because family and genus group definitions of freshwater Rissooidea are predominantly delineated by soft-part anatomy and/or molecular data. [details]

Diagnosis Protoconch low-trochiform; no ornamentation discernable; diameter of initial whorl c. 350 mm. Shell conical, with apical angle of c. 408 and weakly incised sutures, comprising five to six whorls in total. Height of last whorl c. 60% of total shell height. Teleoconch whorls ornamented with one or two distinct, cord-like keels emerging from second to third whorl. Keel(s) and suture subparallel (resulting from allometric growth), producing slightly increasing offset of (lower) keel and lower suture. Aperture broadly ovate, with distinct, blunt angulation between columellar and palatal margins. Umbilicus closed. [details]

Etymology The genus name is a combination of the Vietnamese denomination of northern Vietnam, "Bắc Bộ", and the type genus of the Triculinae, Tricula Benson, 1843. [details]
