Characterization. Shell small, up to 22 mm. Protoconch top damaged, at least 2.5 whorls. Teleoconch whorls carinate, first 4–5 also tuberculate. Spire of moderate height, stepped; outline slightly concave. Sutural ramps concave, ornamented with densely spaced arcuate radial threads and 1–2 weak spiral threads. Last whorl slightly pyriform, outline slightly convex at upper two-thirds, slightly concave at base. Subsutural flexure symmetrical, of moderate depth. Sculpture of last whorl consists of axially striate spiral grooves, becoming narrower or fading near shoulder.

Distribution. Hawaii, Japan to Philippines, and Queensland; Natal and probably Madagaskar, in 35–500 m ( Röckel, Korn & Kohn, 1995). Philippines, 50–150 m ( Raybaudi Massillia, 2008). Hawaii, 70–300 m ( Severns, 2011). Early Pleistocene of Fiji ( Kohn & Arua, 1999a; Kohn & Arua, 1999b). Shells that are possibly Conasprella eugrammata ( Bartsch & Rehder, 1943) are found in the Pleistocene of Vanuatu ( Ladd, 1982).

Remarks. The studied material differs from typical Conasprella eugrammata ( Bartsch & Rehder, 1943) in having a slightly pyriform body whorl, instead of straight-sided, but it matches this species in all other aspects.
