22 mm

Protoconch corroded. Profile of whorls angular. Postnatal whorls 7. Oblique axial ribs 12-13 on 4th and 5th whorls, 14-15 on 6th and 7th, from shoulder to suture, evanescent on base; crossed by 6-7 spiral lirae on 4th and 5th whorls, 7-8 on 6th and 7th, c. 15 on base, including on the latter some intermediaries; no spiral lirae on sulcus, or only extremely faint ones visible in places. Growth-lines forming a nearly even curve on sulcus, without pliculae. Columella curved, canal short, moderately vide. 22 X 10,5 mm. White, middle portion of columella with faint salmon flush. No operculum.
Animal pale. Tentacles short, no eyes. Radula with c. 25 pairs of daggerlike teeth, proximally bifid, enclosing the poison gland, a short process on inner side proximally, apex sharply pointed, not barbed.
Differs from Daphnella sulcicancellata Barnard, 1958 in having fewer ribs and no sculpturing on the sulcus. The radula teeth have some similarity with those figured by Thiele (1929, fig. 456) for a species of Daphnella.

Largest (shell 22 4 x 10.8 mm) of three syntypes best preserved, and here designated as lectotype . Shell white, consisting of 7 preserved whorls (uppermost broken). Protoconch missing. Spirt whorls angulate at periphery, subsutural ramp slightly concave. Axial ribs begin in lower part of subsutural ramp, very rapidly become prominent at shoulder, and gradually weaken below, not reaching canal. Ribs strong, oblique, narrow, 15 ribs on penultimate whorl, 16 on bodywhorl. Some growth lines on subsutural ramp thickened near upper suture. Spiral sculpture on subsutural ramp consisting of weak, narrow threads, which appear at some distance from upper suture and become stronger towards shoulder. Spiral sculpture on subsutural ramp not always visible due to shell erosion. Spiral cords below the shoulder rather wide, flattened, sometimes with a narrower secondary cord in interspaces. Siphonal canal short, slightly twisted. Anal sinus, judging from growth lines, is asymmetrical, with its deepest point in lower half of subsutural ramp. Para-lectotypes are 19.5 x 9.5 and 16.6 x 8 3 mm in size. Larger para-lectotype better preserved, with 15 axial ribs on bodywhorl and wider spiral cords than in lectotype. All three shells have a characteristic light-orange staining on columella.
