Diagnosis.

This species may be recognized by the following: head entirely dark; pronotum widest in posterior third; elytra partly dark, with broadly pale basal area composed of yellow raised marking and slightly darker non-raised area; antennomere 7 distinctly transverse; female tergite X with disc raised medioapically.

Redescription.

Measurements ♀ (n = 5): HW/HL 1.32-1.38; PW/PL 1.28-1.33; EW/ EL 1.15-1.19; ESut/PL 0.83-0.85; PW/HW 1.06-1.12; forebody length 4.9-5.2 mm.

Similar to B. vulneratus and differing only in the following: elytra with broad basal area composed of raised yellow marking and non-raised, slightly darker area (Fig. 6B); middle femur with small ventroapical area darkened; hind femur with dark apical marking slightly larger; head less transverse; elytral suture relatively longer than pronotum at middle; forebody slightly longer; male unknown; female with tergite VIII with emargination narrower, varying from moderately deep U-shape to minute triangular; female tergite X with apical projection distinctly longer than wide, disc distinctly raised at middle, top of raised area slightly depressed to flattened.

Distribution.

Figure 21D. Known only from a small area in Fujian, China.

Bionomics.

Specimens have been collected in April-July at elevations ranging from 900-1100 m.

Comments.

There have been concerns that this species was conspecific with B. taiwanensis due to the lack of a described male specimen and similarities in coloration ( Smetana and Zheng 2000a). These species are both treated as valid herein based on clear differences in antennae and in the structure of female tergite X. This is presently the only described Oriental species with unknown male characters.
