REMARKS

The species, with a partially preserved carapace, is originating from the Miocene of Switzerland. Considering several inaccuracies in Studer’s illustrations, Bachmayer & Rutsch (1962: pl. 2, fig. 1) reproduced the holotype, which has a well-delineated ‘human face’. The sculptured and apparently rounded carapace shows the two main grooves typical of Dorippidae , e.g. the deep precervical and cervical grooves, and a rather straight, prominent posterior rim. The carapace dorsal surface exhibits an ornamented and coarsely granular cardiac region and a tripartite ridge on the branchial region. It is a true dorippid, but not a species of Dorippe and Dorippinae n. status ( Fig. 3A ) and could more likely belong to Phyllodorippinae n. subfam. ( Fig. 3I ) despite the absence of a lateral spine on the margins of the carapace.

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.
