Genus Akanthophoreus Sieg, 1986 a (Restricted synonymy and bibliography) Akanthophoreus Sieg, 1986 a: 21 –24. Guerrero-Kommritz, 2004: 8 –10. Larsen & Wilson, 2002: 2, 14. Leptognathia G.O. Sars, 1882 (partim): Hansen, 1913 [for A. gracilis, A. inermis, A. longiremis and A. multiserratus listed below]. Paraleptognathia Kudinova-Pasternak, 1981 (partim): Guerrero-Kommritz, 2004 [for species listed below]. Sieg, 1986 a: 40–44 [synonymy of P. antarctica with A. antarctica (Vanhöffen, 1914) listed below]. Scoloura Sieg & Dojiri, 1991: 1495–1501. Dojiri & Sieg, 1997: 228–231. Larsen & Wilson, 2002: 2, 14. Type species: Tanais gracilis Krøyer, 1842, by designation (Sieg 1986 a). Species included (Japanese and Kurile-Kamchatka species in bold): A. antarctica (Vanhöffen, 1914), East Antarctica; A. australis (Beddard, 1886) Antarctica, sub-Antarctica, Kerguelen Islands; A. crassicauda n.sp.

Other species that probably belong in this genus but were transferred directly from Leptognathia to Paraleptognathia, or have Paraleptognathia as their primary generic name (Guerrero-Kommritz 2004; Dojiri & Sieg 1997) are excluded here until a formal review/decision is presented.
