Strephonella
"Pillar straight, anterior fasciole flat, with low similar numerous lirations; body lirate".
Type species by original designation: Lamprodoma undatella Lamarck.
Jung (1971: 197) commented: "The type species of Strephonella, the Recent Eastern Pacific O.undatella Lamarck, is only about 12 mm high. The largest specimen of O. undatella at hand measures 16.5 mm in height. The Miocene O. plicata Guppy is an even smaller species than O. undatella. Woodring (1964, p. 278) included O. dimidiata Pilsbry and Johnson (1917: 165; Pilsbry, 1922: 336, pl. 23, fig. 8) from the Miocene of the Dominican Republic in the synonymy of O. plicata, but he excluded O. dimidiata G. B, Sowerby I ... [Sowerby, 1846. Miocene]. ... According to these illustrations O. dimidiata G. B. Sowerby I is also a species of Strephonella. O. robesonensis Gardner from the late Miocene Duplin marl of North Carolina is also a species of Strephonella. It is somewhat larger than the species mentioned above.".

The above implicates synonymisation of Lamprodomina Marwick, 1931, with the present taxon, although the type species of that taxon (Oliva neozelanica Hutton, 1885) is not mentioned.
