Skogsbergiella Kornicker 1975

"Skogsbergiella, new genus

TYPE-SPECIES—Asterope spinifera Skogsberg, 1920.

ETYMOLOGY—The new genus is named after Dr. Tage Skogsberg. Gender: feminine.

REMARKS—This species was included by Poulsen (1965) in his genus Philippiella (see "Remarks" under Empoulsenia).

The genus Skogsbergiella contains 6 species, all of which live in the study area: S. spinifera (Skogsberg, 1920); S. macrothrix, new species; S. skogsbergi (Kornicker, 1971); S. scotti, new species; S. plocus, new species; 5. pax, new species.

DIAGNOSIS OF THE GENUS—Carapace elongate, smooth, with slitlike incisur; infold of right valve only with linear ridge between list and posterior valve margin; on left valve ridge almost coinciding with valve margin; 4-6 processes present between posterior list and posterior valve margin.

First antenna: 3rd joint with 6 dorsal bristles; sensory bristle of 6th joint of female with 1 short proximal and 6 long terminal bristles, except S. macrothrix on which proximal bristle may be long or short and on some species is close to terminal bristles (this species as conceived herein may contain more than one species); d- and e-bristles of 8^th joint well developed, d-bristle shorter than e-bristle.

Second antenna: Endopodite 3-jointed in both sexes, 3rd joint reflexed on adult male.

Mandible: Basale of female with spines and 4-19 bristles along the dorsal margin in addition to terminal pair; dorsal margin of 1st endopodite joint of female only with about 3 short stout terminal spines; 2nd endopodite joint with long lateral bristle between b- and c-bristles. Exopodite about half length of dorsal margin of 1st endopodite joint.

Maxilla: Basale with 1 proximal bristle on ventral margin and 1-5 distal bristles on dorsal margin.

Sixth limb: Anterior margin with 1 upper and 1 lower bristle; posteroventral margin with 12-29 bristles.

Seventh limb: Each limb with 12-25 bristles.

DISTRIBUTION—Members of the genus Skogsbergiella have not been reported from outside the present study area. The northernmost latitude from which the genus has been collected is 38°1S'S. The southernmost locality is in the Weddell Sea (Figure 285). The known depth range of the genus is 6 to 3431 m, but it was only collected once below 2000 m, and twice between 1000 m and 2000 m."
