Alvania minuta is an extinct species of minute sea snail, a marine gastropod mollusc or micromollusk in the family Rissoidae.

[1] Alvania minuta (Golikov & Fedjakov, 1987) is a homonym and has become a synonym of Pusillina tumidula (G. O. Sars, 1878).

The axials are crossed by much weaker spirals, indistinct on early whorls, 4 on penultimate whorl, broad and flatly rounded (interstices sublinear) and cutting up axials into blunt laterally-elongate tubercles.

A fifth spiral emerges from the suture-line on to base and is slightly crenulated by ends of axials.

[3] Fossils of this marine species were found in Tertiary strata in New Zealand
