Abstract: The taxonomy of the deep-water spider crabs of the genus Scyramathia A. Milne-Edwards, 1880, is revised and four extant species are recognised from the Atlantic and western Indian Ocean: S. carpenteri (Norman, in Thomson 1873) (type species), S. umbonata (Stimpson, 1871), S. hertwigi Doflein, in Chun 1900, and S. tenuipes sp. nov. Scyramathia tenuipes sp. nov. from the Mediterreanean is easily distinguished from its congeners by its slender and elongate ambulatory legs. All species are diagnosed and figured. The taxonomy of two allied genera from the Atlantic and Mediterranean, Rochinia A. Milne-Edwards, 1875, and Anamathia Smith, 1885, are also treated and their type species redescribed and figured.

A new genus for Pericera septemspinosa Stimpson, 1871 and Pericera heptacantha Bell, 1836 (Crustacea, Brachyura, Majoidea), based on morphology and molecular data https://zse.pensoft.net/article/50360/ Zoosystematics and Evolution 96(1): 205-216

Abstract: A new genus of majoid spider crab, Pohleus gen. nov. is established for Pericera septemspinosa Stimpson, 1871 and Pericera heptacantha Bell, 1836, based on morphology and molecular data from the partial sequences of the 12S and 16S mitochondrial genes and the 18S small subunit rRNA nuclear locus. The species are re-described and illustrated, based on material from several localities of the western Atlantic and eastern Pacific oceans. The carapace, antennal and pterygostomial spines, male thoracic sternum and first gonopods are distinctive characters, distinguishing Pohleus gen. nov. from species assigned to Macrocoeloma Miers, 1879, where P. septemspinosus and P. heptacanthus are currently included.
