Melanopsis wagneri Roth, 1839 View in CoL (clade C)

Roth (1839) described M. laevigata var. erosa Roth, 1839 from the Peloponnese. However, M. laevigata Lamarck, 1816 is characterized by the low body whorl and high spire with numerous whorls growing slowly and regularly ( Lamarck, 1816: 12, plate 458, fig. 8), strikingly different from our gastropods from clade 3.

In that publication, Roth (1839: 24, pl. 2, fig. 11) described M. wagneri (for the original description see the Supporting Information, File S1) as having the ovate-oblong shell with black periostracum, apex often corroded, broad, ovoid, ovate aperture and prominent callus, in Smyrna [Izmir] collected earlier. The character states listed above, as well as the drawing of Roth (1839: pl. 2, fig. 8) fit our specimens belonging to clade C from Rhodes and the Peloponnese). The type locality at Izmir, western Turkey is not far from our localities. Gambetta (1929) suggested the occurrence of M. wagneri (as a form of M. praemorsa ) on Rhodes.
