Fissarcturus Brandt, 1990

Fissarcturus Brandt, 1990: 129–130 ; Wägele, 1991: 174–177.

Neoarcturus: Wägele, 1991: 182 (part).

Remarks

Members of Fissarcturus differ from Antarcturus in the possession of an elongate setiform unguis on dactyli of pereopods 2–4 and the lateral position of the opening of the groove on the male pleopod 2 endopod. Differences from Neoarcturus were discussed in the section ‘‘Reallocation of non-southern African species ... ’’ above. Most of the species dealt with as members of Neoarcturus by Wägele (1991: 182–191) belong to Fissarcturus and his key could be used to differentiate some.

Twelve, possibly 13, species are included, all from Antarctic waters. They are the type species Fissarcturus emarginatus Brandt, 1990 ; F. stephenseni Wägele, 1991 ; the five species described as members of Neoarcturus by Brandt (1990)— F. elongatus , F. minutus , F. robustus , F. scelerosus , F. stebbingnordenstami ; F. poorei (Kussakin and Vasina, 1998b) from Neoarcturus ; F. mawsoni (Hale, 1946) from ‘ Microarcturus ’; F. hirticornis (Monod, 1926) and F. patagonicus (Ohlin, 1901) from Antarcturus but both placed in ‘ Microarcturus ’ by Nordenstam (1933); plus F. rugosus (Nordenstam, 1933) from ‘ Microarcturus ’. Also to be possibly considered is Antarcturus granulosus Nordenstam, 1933 . See table 1 also. Only species at one time referred to ‘ Microarcturus ’ are dealt with below.
