Santa Maria material examined. Maximum height 1.8 mm, width 3.0 mm. DBUA-F 487-1 (2), Ponta do Castelo, Santa Maria Island, Azores, Touril Complex, Lower Pliocene.

Description. Azorean specimen juvenile, not apt for description.

Discussion. The Azorean specimens represent a juvenile but shows the salient characteristics of the species; the long elongated profile, coarse reticulate sculpture, and most importantly the lamellae on the selenizone, which are relatively coarse and rise above the level of the reticulate sculpture on lateral view. For further comparison, see Ceulemans et al. (2016: 58).

Distribution. Upper Miocene: Atlantic (Tortonian), NW France (Millet 1854, 1865; Brébion 1964; Landau et al. 2017). Lower Pliocene: Atlantic, NW France (Brébion 1964; Ceulemans et al. 2016), Santa Maria Island, Azores (this paper). Upper Pliocene-Lower Pleistocene: NW France (Brébion 1964). Lower Pleistocene: central Mediterranean (Chirli & Forli 2017); eastern Mediterranean (Chirli & Linse 2011). Present-day: Atlantic Canaries (Hernández et al. 2011), Portugal, Morocco and Mediterranean (Poppe & Goto 1992).
