Diagnosis.

Adults of B. taiwanica Döberl are similar to those of B. yehi sp. nov. and B. meihuai sp. nov. in possessing convergent elytral apices. However, adults of B. taiwanica (Fig. 20 A, B ) and B. meihuai sp. nov. (Fig. 18 A, B ) have slender antenna, length of antennomeres VI – X> 0.5 × antennomere I [stout antenna in B. yehi sp. nov., antennomeres VI – X 0.5 × antennomere I (Fig. 25 A, B )]. Adults of B. taiwanica (Fig. 19 ) and B. yehi sp. nov. (Fig. 24 ) possess indistinct or reduced longitudinal ridges on the elytra which are different from B. meihuai sp. nov. by their distinct and sexually dimorphic longitudinal ridges on the elytra (Fig. 17 ). The aedeagus of these species are diagnostic: rounded apex with narrowly rounded process at middle of apical margin in B. taiwanica (Fig. 20 C ), widely rounded apex in B. yehi sp. nov. (Fig. 25 C ), and truncated apex in B. meihuai sp. nov. (Fig. 18 C ).

Description.

Male. Length 1.52–1.67 mm, width 0.80–0.83 mm. General color metallic dark bronze (Fig. 19 A – C ); antennae yellowish brown but six apical antennomeres darker; legs yellowish but apical halves of femora of hind legs darkened. Antenna (Fig. 20 A ) filiform and antennomeres VIII – X wide, ratio of length of antennomeres I – XI to length of antennomere I 1.0: 0.6: 0.5: 0.6: 0.7: 0.6: 0.7: 0.7: 0.7: 0.6: 0.9; ratio of length to width of antennomeres I – XI 2.7: 2.3: 2.4: 2.7: 3.2: 2.4: 2.2: 2.4: 2.0: 1.8: 2.7. Pronotum 1.21–1.23 × wider than long; lateral margins slightly rounded, anterolateral angles separated from lateral margins by weak emarginations, slightly narrowed basally, distance between anterolateral angles 1.04–1.08 × wider than basal margin. Elytra 1.35–1.36 × longer than wide; lateral margins rounded, widest at basal 1 / 3, apex rounded but divergent; dorsoventrally flattened, apex visible in dorsal view; disc with longitudinal lines of coarse punctures and with distinct longitudinal grooves along lines. Tarsomeres I of front and middle legs slightly swollen. Aedeagus (Fig. 20 C, D ) elongate, 5.8 × longer than wide; lateral margins basally and slightly widened towards base, apex narrowly rounded; dorsal opening starting from apical 1 / 7 and basally membranous, tectum composed of three lobes, median lobe more ventral relative to lateral lobes and apical margin truncate, mostly membranous; moderately curved in lateral view; ventral surface with membranous area narrower than dorsal opening, starting from apical 1 / 10–2 / 5.

Female (Fig. 19 D – F ). Length 1.96–2.04 mm, width 1.06–1.13 mm. Antennae similar to males, ratio of length of antennomeres I – XI to length of antennomere I (Fig. 20 B ) 1.0: 0.6: 0.6: 0.5: 0.7: 0.6: 0.7: 0.7: 0.7: 0.7: 1.0; ratio of length to width of antennomeres I – XI 2.8: 2.3: 2.6: 2.6: 3.0: 2.5: 2.5: 2.5: 2.4: 2.0: 3.1. Elytra 1.29–1.36 × longer than wide; lateral margins rounded, widest at basal 1 / 3, apex rounded but divergent; dorsoventrally convex, apex not visible in dorsal view; disc with longitudinal lines of coarse punctures and with distinct longitudinal grooves along punctures. Gonocoxae (Fig. 20 F ) slender, connected at basal 1 / 5; each gonocoxa with seven long setae and one tiny seta from apical 1 / 5 to apex, subapically slightly curved. Ventrite VIII (Fig. 20 E ) weakly sclerotized apically, with several short setae at sides of apex, and some tiny setae at sides of apical margin, spiculum extremely elongate. Spermathecal receptaculum (Fig. 20 G ) strongly swollen, with transverse wrinkles at basal 1 / 2; pump wide and curved, with transverse wrinkles at apical 2 / 3; sclerotized spermathecal canal moderately long before base of spermathecal gland.

Food plants.

Rosaceae : Rubus croceacanthus H. Lév.

Distribution.

This species is widespread in mountainous areas of central Taiwan (Fig. 4 ).
