. The name ''Parthenia'' was created by Lowe in 1840 for the species in this group, but had to be replaced since it was preoccupied by a name for a group of dipterans described by Roubineau-Desvoidy in 1830.

Taxonomy
The Eastern Atlantic and Mediterranean species of the family Pyramidellidae, here listed under the genus ''Parthenina''
Bucquoy, Dautzenberg & Dollfus, 1883, have been included by most 20th-century European authors in the genus ''Chrysallida''
Carpenter, 1856, following a lead by Winckworth (1932). The first explicit statement that this is incorrect was voiced by van Aartsen, Gittenberger & Goud (2000: 21) "None of the many species from European Atlantic and Mediterranean waters currently included in ''Chrysallida'' conforms exactly to the description of the genus sensu stricto", but they still used ''Chrysallida'' as a genus and used ''Parthenina'' and other names as subgenera. Micali, Nofroni & Perna (2012) formally raised ''Parthenina'' to the rank of genus and included a number of European species, whereas other congeners not treated in that paper were still listed in WoRMS and elsewhere as ''Chrysallida''. Hoisaeter (2014) transferred some more species but still listed five species under ''Chrysallida''. The current treatment follows Giannuzzi-Savelli, Pusateri, Micali, Nofroni & Bartolini (2014) who provided a quite sensible treatment and transferred the relevant Mediterranean species to ''Parthenina'' and other genera, without any species retained in ''Chrysallida''. This scheme yet has to be tested against a phylogenetic hypothesis based on molecular sequence data.
