Diagnosis.

Adults of B. wusheensis sp. nov. are not separable from those of B. houjayi sp. nov., B. yuae sp. nov., B. jungchani sp. nov., and B. huangi sp. nov. that are characterized by truncate elytral apices based on external morphology (Figs 10, 12) except for the aedeagus (see below). However, these species can be recognized by their allopatric distributions [ B. wusheensis sp. nov. inhabits at lowlands in Nantou County, B. houjayi sp. nov. in high mountains in Chiayi, Ilan, Hualien, and Nantou counties, B. yuae sp. nov. in lowlands in Taipei and New Taipei Cities, and Ilan County, B. jungchani sp. nov. in high mountains in Taichung and Miaoli counties, B. huangi sp. nov. in lowlands in Miaoli County and high mountains in Hsinchu and Taoyuan counties (Fig. 13)]. Aedeagal shapes are diagnostic [apically tapering aedeagus from apical 1 / 5 in B. wusheensis sp. nov. (Fig. 23), widely rounded apex of aedeagus in B. houjayi sp. nov. (Fig. 11 C), rounded apex of aedeagus with truncate process at middle of apical margin in B. yuae sp. nov. (Fig. 26 C), subapically tapering apex of aedeagus in B. jungchani sp. nov. (Fig. 15 C), and rounded apex of aedeagus with small, rounded process at middle of apical margin in B. huangi sp. nov. (Fig. 14 C)].

Description.

Male. Length 1.57–1.74 mm, width 0.70–0.80 mm. General color metallic dark bronze; antennae yellowish brown but six apical antennomeres darker; legs yellowish but femora of hind legs darkened. Antenna (Fig. 23 A) filiform and antennomeres VIII – X wide, ratio of length of antennomeres I – XI to length of antennomere I 1.0: 0.6: 0.6: 0.6: 0.8: 0.7: 0.8: 0.8: 0.8: 0.7: 1.0; ratio of length to width of antennomeres I – XI 2.6: 2.3: 3.1: 2.7: 3.5: 2.7: 2.5: 2.6: 2.1: 2.0: 2.7. Pronotum 1.22–1.24 × wider than long; lateral margins slightly rounded, disc with lateral depressions at basal 1 / 3, anterolateral angles separated from lateral margins by weak emarginations, slightly narrowed basally, distance between anterolateral angles 1.09–1.17 × wider than basal margin. Elytra 1.40–1.46 × longer than wide; lateral margins rounded, widest at basal 1 / 3, apex truncate; dorsoventrally convex, apex not visible in dorsal view; disc with longitudinal lines of coarse punctures and with indistinct longitudinal grooves along lines, reduced in some individuals. Tarsomeres I of front and middle legs slightly swollen. Aedeagus (Fig. 23 C, D) elongate, 5.8 × longer than wide; parallel-sided, apically narrowed from apical 1 / 5, apex pointed; dorsal opening starting from apical 1 / 10 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 / 20–1 / 2.

Female. Length 1.96–2.30 mm, width 0.87–1.00 mm. Antennae similar to males, ratio of length of antennomeres I – XI to length of antennomere I (Fig. 23 B) 1.0: 0.6: 0.6: 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 2.9: 2.2: 2.7: 2.7: 3.5: 2.8: 2.9: 2.4: 2.2: 2.1: 2.8. Elytra 1.42–1.51 × longer than wide; lateral margins rounded, widest at basal 1 / 3, apex truncate; dorsoventrally convex elytral apex not visible in dorsal view; disc with longitudinal lines of coarse punctures and with indistinct longitudinal grooves along lines, reduced in some individuals. Gonocoxae (Fig. 23 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. 23 E) weakly sclerotized apically, with several short setae at apical area, and some tiny setae at sides of apical margin, spiculum extremely elongate. Spermathecal receptaculum (Fig. 23 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.
