Etymology. In honor of Dana H. Geary (University of Wisconsin, USA), who intensively studied the evolutionary mechanisms in the melanopsids of Late Miocene Lake Pannon.

Type locality. Unnamed outcrop 3 km N of Antirrio, Aetolia-Acarnania, Greece.

Age. "Upper Pliocene" (today probably referable to the lower Pleistocene).

Holotype. Senckenberg Forschungsinstitut und Naturmuseum Frankfurt, no number indicated.

Discussion. This taxon displays a classic case of a primary homonym as a species-group name. The name " posterior " as a species-group name within the genus Melanopsis was already introduced by Papp (1953, p. 133) for a Late Miocene Lake Pannon species from Leobersdorf, Austria, namely Melanopsis impressa posterior Papp, 1953. Lueger (1980, p. 116) later elevated that taxon to species level.
