Scyllarides
Scyllarides is a genus of slipper lobsters. Characteristics. "Scyllarides" is placed in the subfamily Arctidinae, which is differentiated from other subfamilies by the presence of multiarticulated exopods on all three maxillipeds, and a three-segmented palp on the mandible. The only other genus in the subfamily, "Arctides", is distinguished by having a more highly sculptured carapace, with an extra spine behind each eye, and a transverse groove on the first segment of the abdomen. Taxonomic history. In 1849, Wilhem de Haan divided the genus "Scyllarus" into two genera, "Scyllarus" and "Arctus", but made the error of including the type  species of "Scyllarus" in the genus "Arctus". This was first recognised by the ichthyologist Theodore Gill in 1898, who synonymised "Arctus" with "Scyllarus", and erected a new genus "Scyllarides" to hold the species that De Haan had placed in "Scyllarus". Species. "Scyllarides" comprises the following extant species: In addition, two extinct species of "Scyllarides" are known from the Eocene of Europe:
