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 View Figure 10 , 12 View Figure 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 View Figure 13 )]. Aedeagal shapes are diagnostic [apically tapering aedeagus from apical 1 / 10 in B. jungchani sp. nov. (Fig. 15 C View Figure 15 ), rounded apex of aedeagus with truncate process at middle of apical margin in B. yuae sp. nov. (Fig. 26 C View Figure 26 ), apically tapering aedeagus from apical 1 / 5 in B. wusheensis sp. nov. (Fig. 23 C View Figure 23 ), widely rounded apex of aedeagus in B. houjayi sp. nov. (Fig. 11 C View Figure 11 ), and rounded apex of aedeagus with small, rounded process at middle of apical margin in B. huangi sp. nov. (Fig. 14 C View Figure 14 )].

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 View Figure 15 ) 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 View Figure 15 ) 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 View Figure 15 ) 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 View Figure 15 ) 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 View Figure 15 ) 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 View Figure 15 ) 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 View Figure 16 ).

Food plants.

Unknown.

Etymology.

This new species is named for Jung-Chan Chen (陳榮章), the first person to collect specimens.

Distribution.

This species is widespread in alpine areas of central Taiwan (Fig. 13 View Figure 13 ).
