One is a very high and slender shell, with teleoconch sides slightly convex and a reticulated more or less strongly beaded sculpture, and with a strongly elevated protoconch of 3.5 whorls bearing 2 saillant equal and well separated spiral keels, with smooth intervals. We could not find such protococonchs in former descriptions of Cerithiopsidae. For this shell, we propose the new genus Belonimorphis (from Greek, meaning needle-shaped): type species: Belonimorphis belonimorphis n.sp.
