Akanthophoreus cf longiremis (Lilljeborg, 1864) (restricted synonymy and bibliography) Tanais longiremis Lilljeborg, 1864: Lilljeborg, 1865: 23 –25. Leptognathia longiremis: G.O. Sars, 1896: 27, plate XII (= L. gracilis (Krøyer, 1842) not longiremis sensu Lilljeborg, 1864). Hansen, 1913: 69 –70, 74– 76, plate VII figs 3 a–e. Lang, 1957: 49, fig N. Kudinova-Pasternak, 1977: 125 [an uncertain synonymy]. Akanthophoreus longiremis (Lilljeborg, 1864): Sieg, 1986 a; 23, 28, fig 10 (partim, not those derived from G.O. Sars 1896). Paraleptognathia longiremis (Lilljeborg, 1864): Guerrero-Kommritz, 2004: 33 –38, figs 13–15 [an uncertain synonymy]. See Sieg (1983) for the very complex synonymy and bibliography up to date of publication. Remarks. This is an Akanthophoreus species with a very unfortunate taxonomic history, largely because of the error in depicting A. gracilis as this species in the canonical account of Norwegian tanaidaceans (G.O. Sars 1896). The figure given by Hansen (1913) remains the best overall illustration of the species, along with Lang (1957) for cheliped and pereopod variation. Actually a fairly scarce species from shelf and shallow bathyal western European waters at the interface of cold Arctic and warmer Atlantic water-masses (Bird 2001; ined.), A. longiremis has been ( doubtfully) recorded from the Izu-Ogasawara Trench, 6770–6890 metres (Kudinova- Pasternak 1977). It is possible that the following species, A. undulatus n.sp., is the basis for this record, if Kudinova-Pasternak’s view of L. longiremis was that of G.O. Sars.
