REMARKS

This species, known from the Miocene of the Carpathians by an internal mould with a diagenetically deformed and laterally compressed carapace, has been considered to bear some resemblance to extant Cymonomus A. Milne-Edwards, 1880 and even Tymolus Stimpson, 1858 or to homoloids (Müller 1984a: 66, 100, respectively). It may also be noted that transversely aligned ridges cross the branchial regions in Eocene Cymonomidae (De Angeli 2016) . Currently, D. carpathica is regarded as a dorippid, tentatively assigned to either Dorippe (Förster 1979) or Neodoripp e (Müller 1996; Schweitzer et al. 2010; Hyžný 2016) or Medorippe (Karaswa 2000) ; it has also been assumed to be an ethusid (Müller 2006). The posterior margin is ‘bilobated’ (Förster 1979: 92, fig. 3, pl. 2, fig. 3) and concave. In Förster’s sketch and photograph (1979: 92, fig. 3, pl. 2, fig. 3), the carapace dorsal surface bears three parallel lines on each branchial region, the posterior line corresponding to an oblique ‘prominent ridge’. The deep groove that reaches the orbital border is much stronger than that of extant dorippids. It is difficult to assign this species to an existing genus, at least not to Dorippe , Medorippe or Neodorippe .? Dorippe carpathica is somewhat reminiscent of Ethusa popognensis De Angeli, Garassino & Pasini, 2009 , which bears two granulated ridges on each branchial region (see below).
