Rectarcturus kophameli (Ohlin, 1901)

Arcturus Kophameli Ohlin, 1901: 272–273 , pl. 20 figure 5.

‘ Microarcturus ’ kophameli: Nordenstam, 1933: 128 .

Rectarcturus kophameli: Schultz, 1981: 68 ; Park and Wägele, 1995: 71–75, figures 9–12.

Remarks

Nordenstam (1933) listed this as a member of Microarcturus . Park and Wägele (1995) redescribed the holotype female and discussed the differences between Rectarcturus Schultz, 1981 , of which this is the type species, and Neoarcturus . Unfortunately their discussion treated species of Neoarcturus , Austroarcturus and Fissarcturus synonymously. They realized the differences between Brandt’s (1990) species (referred here to Fissarcturus ) and holidoteids (see discussion under Neoarcturus above), and that Rectarcturus is closer to Fissarcturus than to Neoarcturus s. s. Significant differences are that the groove on the male pleopod 1 endopod opens distolaterally in Rectarcturus (not laterally as in Fissarcturus ), there are no paired pleotelsonic spines, pereopods 5–7 lack robust setae on the posterior margin of carpus and propodus, and the unguis of pereopods 2–4 is shorter than the body of this article (longer and setiform in Fissarcturus ).
