Material examined. 1 adult male, 5.2 mm; 1 ovigerous female 5.4 mm; 1 female; 2 juveniles 3.0 mm (St. 34: grab sampling; 18°23.116´S, 11°55.289´E) [ZMB 27920]; 1 female (St. 33: grab sampling; 18°11.444´S, 11°50.475´E); 1 female (St. 32: grab sampling; 17°57.633´S, 11°46.104´E); 1 female (St. 16: grab sampling; 16°59.522´S, 11°31.098´E); 1 female; (St. 23: grab sampling; 17°18.946´S, 11°43.389´E); 3 females (St. 8: grab sampling; 12°05.273´S, 13°42.047´E)
Description. preadult male, 5.2 mm total length. Integument soft. Carapace (Fig. 8 A) about twice as long as high; antero-lateral angle prominent and acute; antennal notch deeply indented; dorsal carinae on carapace and pedigerous somites; without lateral carinae on carapace; pseudorostral lobes meeting for short distance in front of eyelobe; eyelobe rounded; eye prominent.
First antenna (Fig. 8 B), peduncle triarticulate, article 1 twice as long as article 2 and 1.5 times as long as article 3; flagellum biarticulate, very short, as long as peduncle article 2, with four aesthetascs distally; accessory flagellum rudimentary. Second antenna reaches as far as third pedigerous somite.
Maxilliped 3 (Fig. 8 C), basis slightly more than twice as long as following five segments combined length, arcuate, with its distal extension reaching to end of the merus; with row of nine plumose setae on the inner margin; outer margin of process with a row of short, fine setulae; merus and carpus slightly produces distally; carpus broad, with one plumose setae distal and few plumose setae on inner margin; dactylus slender, with short setae distally and a row of setulae on inner margin.
Pereopods: pereopod 1 (Fig. 8 D), basis 1.5 times longer than following five segments combined length, arcuate, with one long plumose seta distally; ischium short; ischium and merus together slightly longer than propodus; propodus and dactylus equal in length; carpus about 1.7 times longer than propodus. Pereopod 2 (Fig. 8 E), basis long and slender, about 1.4 times as long as the remaining segments; ischium fused with basis; carpus and dactylus each about twice as long as merus and also propodus; merus and carpus each bearing one strong simple setae. Pereopod 3 (Fig. 9 A) basis long and slender, about 1.2 times as long as the remaining segments, with one plumose setae distally; ischium short, with one long acuminate seta distally; merus, carpus and propodus of same length more than twice as long as ischium, with one long strong simple setae distally; dactylus short. Pereopod 4 (Fig. 9 B) basis as long as the remaining segments; rest of the limb similar to pereopod 3. Pereopod 5 (Fig. 9 C) basis shorter than the remaining segments; rest of the limb similar to pereopod 3.
Uropod (Fig. 9 D) peduncle about twice as long as rami; inner margin with hyaline serrations, interspersed with several short setae; exopod and endopod of same length; endopod uniarticulate, inner margin with six serrated setae interspersed with hyaline serrations and one terminal setae; exopod with five plumose setae on inner edge and two terminal setae.
Remarks. B. glabra was described by Jones (1956) from an ovigerous female. He found three females and six juveniles from plankton hauls. The male was unknown until know. The morphological features of the adult male agree well with the description of the female. However, the basis of the maxilliped 3 in the preadult male is slightly more than twice as long, and in female it is only twice as long, as the remaining five segments together. This also applies to pereopod 1. The basis in preadult male is 1.5 times longer than the following five segments combined, whereas it is only 1.25 times longer in female. Another difference applies to the lateral carina on carapace, which is only faintly marked in females but not in preadult male. B. glabra seems to be endemic for the area of the Angola current on the shelf coast off Angola and northern Namibia.
Distribution. South West Africa (Namibia and Angola), from 20°11’ S to 12°0’S, 19–105 m and planktonic.
