REMARKS

Gemmellaro (1914, as Dorippe lanata ) was the first to report some specimens from the Late Pleistocene of Sicily. The second fossil report in the Mediterranean area is from Garassino et al. (2014b: fig. 2C) for a well-preserved male specimen (carapace and ventral surface) from the Late Pleistocene of Calabria (southern Italy): all its features seem to indicate a Medorippe lanata ( Figs 3C ; 22A, B ), with its lateral spine, the two main carapace grooves, the rather straight posterior margin of the carapace. The cardiac region is ornamented, but the Y-shaped ridge characteristic of the extant species is not clearly distinct. Anyway, the species belongs to the Medorippinae n. subfam.

FIG. 3. — Carapace diversity in the nine dorippid genera: A, Dorippe Weber, 1795 (D. quadridens); B, Dorippoides Serène & Romimohtarto, 1969 (D. facchino); C, Medorippe Manning & Holthuis, 1981 (?M. crosnieri); D, Heikeopsis Ng, Guinot & Davie, 2008 (H. aff. japonica); E, Neodorippe Serène & Romimohtarto, 1969 (N. callida); F, Nobilum Serène & Romimohtarto, 1969 (N. histrio); G, Paradorippe Serène & Romimohtarto, 1969 (P. cathayana); H, Philippidorippe Chen, 1986 (P. philippinensis); I, Phyllodorippe Manning & Holthuis, 1981 (P. armata). A-G, I: modified from Sin et al. (2009: fig. 3); H, from Chen (1986: pl. 1, fig. 3). The strip, which is shown here only in Dorippoides facchino (Herbst, 1785) and Medorippe?crosnieri Chen, 1988, is in fact present in all species of dorippids.
