Ocinebrina landaui Group

Discussion. This group comprises Ocinebrina bellissima sp. nov. and Ocinebrina landaui Kovács, 2019 . These species are characterized by ovate-globose shells, regular spiral sculpture of well-developed P1–P6 and s1–s6, with more prominent P5 at position of a small labral tooth. The broad axial ribs are arranged in spirals in apical view. Both species have a prominent fasciole, a very broad pseudoumbilicus, an aperture with prominent denticles, and short, closed siphonal canal. The extant Mediterranean Ocinebrina aciculata ( Lamarck, 1822) may be related to the Ocinebrina landaui group due to the presence of a more prominent cord forming a labral tooth, and the broad, fused siphonal canal. The species also resembles the Pliocene specimens of Ocinebrina bicaudata ( Borson, 1821) figured by Goret et al. (2013). Nevertheless, we assume that the labral tooth might have appeared independently in different lineages.

The apertural features are reminiscent of those of Inermicosta Jousseaume, 1880 [type species Murex fasciatus G. B. Sowerby II, 1841 [= Inermicosta inermicosta (E.H. Vokes, 1964) ; present-day, western Africa] as reviewed by Vermeij & Houart (1999) but Inermicosta is trivaricate and lacks a labral tooth. A revision of other Miocene species in the Circum-Mediterranean Region will be needed to establish if this group occurs outside the Paratethys.
