Ranina propinqua Ristori, 1891

Fig. 1F

Material and measurements: One incomplete carapace (MSNM i27876 – lcxp: 47 mm).

Description: Carapace convex dorsally, covered by subtriangular granular tubercles, uniformly arranged along the antero- and posterolateral margins, more scarce on gastric regions; anterolateral spines incomplete.

Discussion. Pasini, Garassino & De Angeli in Baldanza et al. (2014: 274) discussed the specimens of Ranina known to date in the fossil record of Italy, re-describing the main characters of Ranina propinqua . The studied specimen preserves just the left side of the carapace, including the preorbital and the incomplete extraorbital spines, showing the main characters of Ranina Lamarck, 1801 . Moreover, the above-mentioned characters of the studied specimen are typical of R. propinqua , to which it is assigned. Ranina propinqua was previously described from Pliocene sandy deposits of Via della Madonna degli Angeli in Città della Pieve (Perugia, Umbria, central Italy) by Ristori (1891a) [these deposits are now referred to the Gelasian-Calabrian interval (Early Pleistocene) see Baldanza et al., 2014)]; and recently from the Early Pleistocene of Fabro Scalo (Terni, Umbria, central Italy) by Baldanza et al. (2014) and from the Early Pleistocene of Orzalume Cottano area (Orvieto, Umbria, central Italy) (Famiani et al., in press). The discovery of R. propinqua from Trumbacà, attests the presence of Ranina in the southern Mediterranean area still during the Tyrrhenian (Late Pleistocene).
