Alvania eucraspeda

Alvania eucraspeda is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae.

The Australian Faunal Directory considers ''Rissoa hulliana var. eucraspeda a synonym of Alvania (Alvania) fasciata'' (Tenison-Woods, 1876)

Description
The length of the shell attains 2 mm, its diameter 1.5 mm.

(Original description) This deep-sea variety differs from the typical shore form by being pure white, slightly larger and comparatively broader, and by having fewer and more prominent radials. Thus it acquires a lip broader and more scalloped, approaching a varix.

Distribution
The holotype of this species was found off Cape Wiles, South Australia.
