Diagnosis.

Adults of B. yehi sp. nov. are similar to those of B. taiwanica Döberl and B. meihuai sp. nov. in possessing convergent elytral apices. However, adults of B. yehi sp. nov. are recognized by their stout antennae, length of antennomeres VI – X 0.5 × length of antennomere I (Fig. 25 A, B View Figure 25 ) [> 0.5 × in B. taiwanica (Fig. 20 A, B View Figure 20 ) and B. meihuai sp. nov. (Fig. 18 A, B View Figure 18 )]. Adults of B. meihuai sp. nov. are characterized by their distinct and sexually dimorphic longitudinal ridges on the elytra (Fig. 17 View Figure 17 ) [indistinct or reduced longitudinal ridges on the elytra in B. taiwanica (Fig. 19 View Figure 19 ) and B. yehi sp. nov. (Fig. 24 View Figure 24 )]. The aedeagi of these species are diagnostic: truncate apex in B. meihuai sp. nov. (Fig. 18 C View Figure 18 ), rounded apex with narrowly rounded process at middle of apical margin in B. taiwanica (Fig. 20 C View Figure 20 ), and widely rounded apex in B. yehi sp. nov. (Fig. 25 C View Figure 25 ).

Description.

Male. Length 1.39–1.57 mm, width 0.69–0.78 mm. General color metallic dark bronze (Fig. 24 A – C View Figure 24 ); antennae yellowish brown but six apical antennomeres darker; legs yellowish but femora of hind legs darkened. Antenna (Fig. 25 A View Figure 25 ) filiform and antennomeres VIII – X wide, ratio of length of antennomeres I – XI to length of antennomere I 1.0: 0.5: 0.4: 0.5: 0.5: 0.5: 0.5: 0.5: 0.5: 0.5: 0.7; ratio of length to width of antennomeres I – XI 2.9: 2.0: 1.8: 2.0: 2.3: 2.2: 2.0: 1.9: 1.5: 1.6: 2.3. Pronotum 1.22–1.25 × wider than long; lateral margins slightly rounded, anterolateral angles separated from lateral margins by weak emarginations, widest at middle, slightly narrowed basally, distance between anterolateral angles 0.99–1.01 × wider than basal margin. Elytra 1.28–1.33 × longer than wide; lateral margins rounded, widest at basal 1 / 3, apex widely rounded and converge; dorsoventrally flattened, apex visible in dorsal view; disc with longitudinal lines of coarse punctures but lacking longitudinal grooves and ridges. Tarsomeres I of front and middle legs strongly swollen. Aedeagus (Fig. 25 C, D View Figure 25 ) elongate, 5.3 × longer than wide; lateral margins basally and slightly widened towards base, apex widely rounded; 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 / 20–2 / 5.

Female. Length 1.63–1.73 mm, width 0.81–0.89 mm. Antennae similar to males, but antennomeres VIII – X wider than those of males, ratio of length of antennomeres I – XI to length of antennomere I (Fig. 25 B View Figure 25 ) 1.0: 0.6: 0.4: 0.4: 0.5: 0.5: 0.5: 0.5: 0.5: 0.5: 0.8; ratio of length to width of antennomeres I – XI 2.4: 2.0: 1.9: 1.7: 2.0: 1.8: 1.5: 1.3: 1.4: 1.4: 2.1. Elytra 1.28–1.32 × longer than wide; lateral margins rounded, widest at basal 1 / 3, apex convergent; dorsoventrally convex, apex not visible in dorsal view; disc with longitudinal lines of coarse punctures but lacking longitudinal grooves and ridges. Gonocoxae (Fig. 25 F View Figure 25 ) slender, connected at basal 1 / 5; each gonocoxa with seven long setae and one tiny setae from apical 1 / 5 to apex, subapically slightly curved. Ventrite VIII (Fig. 25 E View Figure 25 ) 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. 25 G View Figure 25 ) 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.

Individuals collected from Hehuanshan (合歡山) (Fig. 24 D – F View Figure 24 ) have longitudinal grooves connected with lines of coarse punctures on the elytra.

Food plants.

Rosaceae : Fragaria hayatai Makino.

Etymology.

This new species is named for Dr. Wen-Bin Yeh (葉文斌), who worked as professor at the National Chung Hsing University and collected most of the type series.

Distribution.

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