2013 Malea orbiculata (Brocchi) – LANDAU et al., p. 123, pl. 17, fig. 1 (cum syn.).

Material – Ten specimens (SL 20–42); in private collections.

Description – Globose shell, low spire, four convex teleoconch whorls, last whorl constricted at the base. Elongate aperture, denticulate outer lip thickened by labral varix, excavated columella with folds, short and wide siphonal canal, short fasciole. Spiral sculpture of broad, slightly rounded cords (16 on the last whorl), narrow interspaces, axial sculpture of fine growth lines.

Remarks – The species was frequently cited as M. denticulata (Deshayes) in the literature. According to the revision of orbiculata ( LANDAU et al. 2004) , Brocchi’s specimen represents a juvenile form, therefore denticulata is a junior synonym. M. orbiculata is a rare element of the mollusc assemblage of Letkés.

Distribution – Karpatian: CP ( Hungary), Langhian: NEA ( France), Badenian: CP ( Austria, Hungary, Poland), Serravallian: PMS ( Turkey), Tortonian: NEA ( Portugal), PMS ( Italy). For Pliocene range see LANDAU et al. (2013).
