1923: 12 unnumbered plate, fig. 16 [LXVIII: 1 317, 1319, fig. 16]—available name

Type material. MCZR –M–16253/H —1 sh (Holotype) glued on a paper stick, “cymelium typ. Monts. Bengasi !! Fig. l6 ”

Type locality. Coasts of Cirenaica (Libya).

Remarks. Nordsieck (1972: 32) raised this varietal name to the rank of subspecies. Oliverio & Tringali (2001: 135; 130, fig. 45) already figured the holotype and suggested that it belongs to Haminoea hydatis (Linnaeus, 1758) . The systematics of the genus Haminoea is, however, quite puzzling, shell morphology alone of little or no use to distinguish species in this group. The correct identity of Haminoea cymoelium needs to be clarified within a revision of all Mediterranean congeneric species. Recorded by MolluscaBase (2018) as a synonym of Haminoea

hydatis (Linnaeus, 1758) .
