Diagnosis.

Adults of B. yuae sp. nov. are not separable from those of B. houjayi sp. nov., B. wusheensis 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. yuae sp. nov. inhabits lowlands in Taipei and New Taipei Cities, and Ilan County, B. wusheensis sp. nov. in lowlands of Nantou County, B. houjayi sp. nov. in high mountains of Chiayi, Ilan, Hualien, and Nantou counties, B. jungchani sp. nov. in high mountains of Taichung and Miaoli counties, B. huangi sp. nov. in lowlands of Miaoli County and high mountains of Hsinchu and Taoyuan counties (Fig. 13 )]. Aedeagal shapes are diagnostic [rounded apex of aedeagus with truncate process at middle of apical margin in B. yuae sp. nov. (Fig. 26 C ), apically tapering aedeagus from apical 1 / 5 in B. wusheensis sp. nov. (Fig. 23 C ), widely rounded apex of aedeagus in B. houjayi sp. nov. (Fig. 11 C ), subapically tapering apex of aedeagus in B. jungchani sp. nov. (Fig. 15 C ), and rounded apex of aedeagus with a small, rounded process at middle of apical margin in B. huangi sp. nov. (Fig. 14 C )].

Description.

Male. Length 1.53–1.67 mm, width 0.76–0.80 mm. General color metallic dark bronze; antennae yellowish brown but six apical antennomeres darker; legs yellowish but femora of hind legs darkened. Antenna (Fig. 26 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: 0.5: 0.6: 0.6: 0.7: 0.7: 0.7: 0.6: 0.8; ratio of length to width of antennomeres I – XI 2.6: 2.1: 2.2: 2.4: 2.6: 2.5: 2.3: 2.0: 2.1: 1.8: 2.4. Pronotum 1.24–1.25 × wider than long; lateral margins slightly rounded, anterolateral angles separated from lateral margins by weak emarginations, slightly narrowed basally, distance between anterolateral angles widest, 1.10–1.15 × wider than basal margin. Elytra 1.31–1.34 × longer than wide; lateral margins rounded, widest at basal 1 / 5, apex truncate; dorsoventrally flattened, apex visible in dorsal view; disc with longitudinal lines of coarse punctures, and indistinct longitudinal grooves along punctures present only near base, no ridges present between longitudinal grooves. Tarsomeres I of front and middle legs slightly swollen. Aedeagus (Fig. 26 C, D ) elongate, 6.6 × longer than wide; parallel-sided, apically and strongly tapering near apex, apex with one transverse process, apical margin truncate; 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 slender and small, starting from apical 1 / 8–1 / 3.

Female. Length 1.74–1.78 mm, width 0.86–0.92 mm. Antennae similar to males, ratio of length of antennomeres I – XI to length of antennomere I (Fig. 26 B ) 1.0: 0.6: 0.5: 0.6: 0.7: 0.6: 0.7: 0.6: 0.6: 0.6: 0.8; ratio of length to width of antennomeres I – XI 2.8: 2.5: 2.9: 2.9: 3.4: 2.5: 2.5: 2.3: 2.2: 2.0: 2.5. Elytra 1.31–1.38 × 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 indistinct longitudinal grooves along punctures present only near base, no ridges present between longitudinal grooves. Gonocoxae (Fig. 26 F ) slender, connected from basal 1 / 5 to base; each gonocoxa with seven long and one tiny setae from apical 1 / 5 to apex, subapically slightly curved. Ventrite VIII (Fig. 26 E ) weakly sclerotized apically, with several short setae at sides of apex, spiculum extremely elongate. Spermathecal receptaculum (Fig. 26 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.
