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.
