Description. Length 6 – 7.5 mm, width of midbody metazonae 0.8 – 1.0 mm (male, female), metazonite to prozonite width ratio ca 1.5 – 1.6 ( Fig. 29A View FIGURE 29 ). Coloration uniformly pallid to light yellow.
All characters as in B. assimilis ( Fig. 29A View FIGURE 29 ), except as follows. In width, collum <2 <3 <head = 4 <5. Paraterga well-developed, their fore margins nearly straight, while anterolateral corners clearly angular; caudolateral corner mostly acute-angled and dentiform starting with segment 5, subspiniform and drawn behind rear tergal margin starting with segment 15 ( Fig. 29A View FIGURE 29 ). Tergal setae mostly very short and subclavate. Metatergal sculpture indistinct, but at least middle and caudal rows of flat small tubercles visible. Male legs clearly incrassate compared to female, but male prefemora not bulging laterad; sphaerotrichomes absent ( Fig. 29B View FIGURE 29 ). Gonopod ( Fig. 29C – 29G View FIGURE 29 ) bipartite, stout, exomere with only a single, small, apical tooth (e).
