Type species.

Rochinia gracilipes A. Milne-Edwards, 1875, by monotypy; gender feminine. Monotypic.

Remarks.

The study by Tavares and Santana (2018: 222) suggests that Rochinia sensu stricto "should be restricted to its type species, R. gracilipes A. Milne-Edwards, 1875 with perhaps a few additional closely related species". To this effect, Tavares and Santana (2018: 223) left the rest of the other species, mainly from the Indo-West Pacific region, in Rochinia sensu lato. Ng and Richer de Forges (2013) had discussed the problems with Rochinia at length and suggested that more genera may need to be recognised. The recent work on the epialtid spider crabs from Papua New Guinea by Lee et al. (2019) described two species from Rochinia sensu lato and transferred four Rochinia sensu lato species to Crocydocinus Lee, Richer de Forges & Ng, 2019. Lee et al. (2019) noted that a revision for Rochinia is in preparation (see also Lee et al. 2017). In this study, one species, S. hertwigi Doflein, in Chun 1900, is transferred out of Rochinia sensu lato and back to Scyramathia A. Milne-Edwards, 1880.
