Deepwater species. Shell strongly channeled suture. Color cream to ligh-pink. Size about 8 mm, fusiform, color cream to ligh-pink. Protoconch smooth, mamillated, glossy, with about 2 whorls. Limit protoconch - teleoconch well marked. Aperture with about half of total shell length. Teleoconch with about 4-5 convex whorls. Suture very channeled, furrow equivalent to cord width. Shell tall, uniformly sized axial ribs projected outside. Each node with tip rounded, smooth, disposed axially, between each node forming a shallow space, with about 8 node axial ribs in last whorl. Last whorl almost duble size of spire lenght.

Diptychophlia hubrechti is herein described from empty shells. D. hubrechti differ from type species D. occata (Hinds 1844), in outline and having a strongly channeled suture, being the second specie described for this genus. The depth of ocurrence and type locality appears to be also different, as D. occata occurs in Panama at 72 m and D. hubrechti in the N.E Brazil about 280 m. The protoconch of D. hubrechti resembles that of the genus Cerithiopis.
Because this description is based only by shell characters, the generic placement of the species is relatively arbitrary, without knowledge of the radular morphology. Therefore, the precise generic allocation of the new species described herein must remain provisional.
