Diagnosis.

Adults of B. alishanensis sp. nov. are similar to those of B. wusheensis sp. nov., B. houjayi sp. nov. (Figs 10 View Figure 10 , 12 View Figure 12 ), B. yuae sp. nov., B. jungchani sp. nov., and B. huangi sp. nov. (Fig. 16 View Figure 16 ) in possessing truncate elytral apices. It can be recognized easily by fine punctures on elytra (Fig. 2 View Figure 2 ). The aedeagus of this new species is similar to that of the sympatric species B. houjayi sp. nov. but differs by the wider subapical area (Fig. 3 C View Figure 3 ) [apically narrow aedeagus in B. houjayi sp. nov. (Fig. 11 C View Figure 11 )].

Description.

Male. Length 1.44–1.61 mm, width 0.74–0.80 mm. General color metallic dark bronze (Fig. 2 A – C View Figure 2 ); legs yellowish but hind femora darkened. Antenna (Fig. 3 A View Figure 3 ) 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: 0.8: 0.6: 0.7: 0.7: 0.6: 0.6: 0.9; ratio of length to width of antennomeres I – XI 2.9: 2.5: 2.3: 2.5: 3.4: 2.5: 2.4: 2.4: 1.9: 1.9: 2.6. Pronotum 1.19–1.25 × wider than long; lateral margins slightly rounded, anterolateral angles separated from lateral margins by weak emarginations, slightly narrowed basally, distance between anterolateral angles 1.13–1.17 × wider than basal margin. Elytra 1.27–1.30 × 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 fine punctures and with indistinct longitudinal grooves along lines present near base and sides. Tarsomeres I of front and middle legs slightly swollen. Aedeagus (Fig. 3 C, D View Figure 3 ) elongate, 5.8 × longer than wide; narrowest at apical 1 / 3, apically widened towards apical 1 / 7 and then narrowed, apex widely rounded, basally widened near base; dorsal opening starting from apical 1 / 10 and basally membranous, tectum composed of two lobes, mostly membranous; slightly curved in lateral view; ventral surface with membranous area narrower than dorsal opening, starting from apical 1 / 10 to 2 / 5.

Female (Fig. 2 D – F View Figure 2 ). Length 1.75–1.93 mm, width 0.85–0.96 mm. Antennae similar to males, ratio of length of antennomeres I – XI to length of antennomere I (Fig. 3 B View Figure 3 ) 1.0: 0.6: 0.5: 0.5: 0.7: 0.6: 0.7: 0.7: 0.6: 0.6: 0.9; ratio of length to width of antennomere I – XI 2.6: 2.3: 2.4: 2.3: 2.8: 2.2: 2.2: 2.1: 1.8: 1.9: 2.5. Elytra 1.37–1.38 × 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 fine punctures and with indistinct longitudinal grooves along lines, reduced in some individuals. Gonocoxae (Fig. 3 F View Figure 3 ) slender, connected with each other 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. 3 E View Figure 3 ) weakly sclerotized apically, with several short setae at apical area, and some tiny setae at apical margin, spiculum extremely elongate. Spermathecal receptaculum (Fig. 3 G View Figure 3 ) 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.
