| | | | | | | Ref.: | | | Markhaseva, 1993 a (p.50, figs.F,M); 1996 (p.81, fgs.F,M) |  issued from : E.L. Markhaseva in Zoosyst. Rossica, 1993, 2 (1). [p.49, Figs.11-23]. Female (from Norway): 11-12, habitus (dorsal and lateral, respectively); 13, forehead (lateral); 14-15, posterior of prosome (dorsal and lateral, respectively); 16, genital segment (lateral); 17, rostrum; 18, A1; 19, A2; 20, Md (mandibular palp); 21, P1; 22, P2; 23, exopod of A2. Holotype: 11-22 from Raunefjorden (South of Bergen); paratype: 23 from Langesundsfjorden (Norway). Nota : Cephalothorax 4 times longer than urosome. Rostral rami divergent. Points of thoracic segment 5 posterior corners extending to posterior border of genital segment (dorsal and lateral view). Spematheca elongate, oval. Exopodite 1 of A2 with 1 seta, exopodite 2 with 3 setae. Endopodite 1 of Md with 2 setae (sometimes with a small 3rd seta), endopodite 2 with 9 long terminal and 1 posterior short . Posterior surface of Mx1 gnathobase with 4 setae, endopodite with 16 setae. External spine on exopodite 1 of P1 long, almost reaching the middle of exopodite 2 spine. Endopod of P2-P4 with minute surface spinules.

 issued from : E.L. Markhaseva in Zoosyst. Rossica, 1993, 2 (1). [p.450, Figs.24-25]. Female (from Raunefjorden): 24, P3; 25, P4. Nota : Coxopodite of P4 with thickened hairs along internal border. Terminal spines of exopodite 3 of P3-P4 with 20 and 23 denticles, respectively.

 issued from : E.L. Markhaseva in Zoosyst. Rossica, 1993, 2 (1). [p.51, Figs.26-34]. Male (from Langesundsfjorden, Norway): 26-27, habitus (dorsal and lateral, respectively); 28-29, posterior of prosome and urosome (dorsal and lateral, respectively); 30, rostrum; 31, A2; 32, Mx1; 33, P1; 34, P5. Nota : Cephalothorax about 3.3 times longer than urosome. Rostral rami divergent. A1 reaching posterior border of urosomal segment 4. Points of posterior thoracic segment 5 corners exceeding posterior border of genital segment, covering the proximal third of urosomal segment 2. Oral parts rudimental, setation partly reduced. Md palp base with 1 seta, endopodite 1 without setae, endopodite 2 with 8 setae. protopodite of Mxp without setae, endopodite 1 with 3 medial setae. External spines on exopodite 1-exopodite 3 of P1 shorter than in female. P2-P4 of the same structure as in female, but P4 coxopodite without hairs along internal border. P5 very similar to that of B. armatus, but distal (3rd) segment of right P5 with 2 terminal and 1 external spines.
