The species was first described by Paul Bartsch in 1915 [1] Oskars and Malaquias 2020 [2] found that the original description of Haminoea natalensis shows a shell with longitudinal growth lines and a large anterior aperture, which is a close match to H. alfredensis.

Due to this Oskars and Malaquias considered H. natalensis as a potential senior synonym of H. alfredensis.

The editors of World Register of Marine Species and Molluscabase has decided on considering Haminoea alfredensis a junior synonym of H. natalensis.

[3] Haminoea alfredensis has a length of 9–17 mm, and it has a broad radular ribbon with about 40 teeth in each half row.

The color of this species is translucent green, dotted with yellow to orange spots.
