MACROSCAPHA SP. View in CoL NOV. 3 ( FIGS 43 View Figure 43 , 45B)

1989a in part Macrocyprina tensa, Hartmann, 1989a: 220

Material: 5 live specimens.

1 A F, 4 juveniles were contained in a glass with glycerine, labelled ‘ K- 33786 a. Macrocyprina tensa, Süd-Georgien, WH 68/1, Stat. 79, l. Mü-Sie, 10.2.1985, d. Hartmann, 1988 , 1 ♀, L.’. ZMH K-33786 a. These specimens were studied by Hartmann (1989a) .

4 RV, 2 LV, were contained on a micropalaeontological slide, labelled ‘ K- 33786 b. Macrocyprina tensa, Süd-Georgien, WH 68/1, Stat. 79, l. Mü-Sie, 10.2.1985, d. Hartmann, 1988 ZMH K-33786 b. These specimens were studied by Hartmann (1989a). This specimen is herein illustrated in Figure 47K View Figure 47 .

Distribution ( Fig. 43 View Figure 43 ): Northern Scotia Sea, off South Georgia, 145- 357 m.

Valve measurements ( Fig. 45): A LV L 1.86 mm, H 0.71 mm; (A-?2) LV L 1.16–1.25 mm, H 0.44–0.48 mm; (A–?2) RV L 1.17–1.26 mm, H 0.44–0.50 mm; (A–?3) RV L 0.84 mm, H 0.25 mm.

Remarks: The lateral LV outline of the?adult female collected off South Georgia ( ZMH K- 33786, Fig. 47K View Figure 47 ) is similar to but presents a more arched dorsal margin than valves of Macroscapha sp. nov. 1. Furthermore, the South Georgian specimen is considerably smaller (1.88 mm) than adults of the latter species (length from 2.10 to 2.24 mm). Consequently, if the photographed valve ( Fig. 47K View Figure 47 ) really belongs to an adult female, it most probably belongs to a different species than Mh. sp. nov. 1.

Remarks: These specimens are left in open nomenclature (1) because of the lack of male soft parts, or (2) because dissected appendages of more than one specimen were mixed in single tubes; and/or (3) because the valves are completely decalcified.
