Diagnosis.

Adults of B. jungchani sp. nov. are not separable from those of B. houjayi sp. nov., B. wusheensis sp. nov., B. yuae 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. jungchani sp. nov. inhabits high mountains in Taichung and Miaoli counties, B. yuae sp. nov. in lowlands of Taipei and New Taipei Cities, and Ilan County, B. wusheensis sp. nov. in lowlands of Nantou County, B. houjayi sp. nov. in high mountains in Chiayi, Ilan, Hualien, and Nantou counties, B. huangi sp. nov. in lowlands of Miaoli County and high mountains of Hsinchu and Taoyuan counties (Fig. 13)]. Aedeagal shapes are diagnostic [apically tapering aedeagus from apical 1 / 10 in B. jungchani sp. nov. (Fig. 15 C), 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), 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 1.93–2.01 mm, width 0.94–0.97 mm. General color metallic dark bronze; antennae and legs reddish brown. Antenna (Fig. 15 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: 0.7: 0.7: 0.8: 0.7: 0.7: 0.6: 0.9; ratio of length to width of antennomeres I – XI 2.7: 2.3: 2.6: 2.4: 3.0: 2.7: 2.4: 2.3: 2.2: 2.1: 3.0. Pronotum 1.22–1.25 × wider than long; lateral margins slightly rounded, anterolateral angles separated from lateral margins by weak emarginations, slightly narrowed basally, distance between anterolateral angles 1.14–1.15 × wider than basal margin. Elytra 1.31–1.35 × 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 distinct longitudinal grooves along punctures, punctures and grooves apically abbreviated, lacking ridges present between longitudinal grooves. Tarsomeres I of front and middle legs slightly swollen. Aedeagus (Fig. 15 C, D) elongate, 6.4 × longer than wide; parallel-sided, apically tapering from apical 1 / 10; moderately curved in lateral view; dorsal opening starting from apical 1 / 15, basally weakly sclerotized; tectum composed of three lobes, median lobe more ventral relative to lateral lobes and apical margin truncate, mostly membranous; moderately curved subapically and medially in lateral view; ventral surface with membranous area same width and height as dorsal opening, starting from apical 1 / 15 to 1 / 3.

Female. Length 2.20–2.34 mm, width 1.06–1.17 mm. Antennae similar to males, ratio of length of antennomeres I – XI to length of antennomere I (Fig. 15 B) 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 2.9: 2.5: 2.6: 3.0: 3.6: 2.8: 2.9: 2.5: 2.2: 2.0: 2.6. Elytra 1.32–1.38 × longer than wide; lateral margins rounded, widest at basal 1 / 5, apex truncate; dorsoventrally convex, apex not visible in dorsal view; disc with longitudinal lines of coarse punctures, and indistinct longitudinal grooves along punctures, lacking ridges present between longitudinal grooves. Gonocoxae (Fig. 15 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. 15 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. 15 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.

Variation.

Some individuals have reddish-brown elytra, especially from Anmashan (鞍馬山) (Fig. 16).

Etymology.
