Diagnosis.

Adults of B. chungi sp. nov., B. tsoui sp. nov., and B. choui sp. nov. are recognized by their strongly apically narrowed elytra, and divergent elytral apices, but B. chungi sp. nov. and B. tsoui sp. nov. differ in possessing flattened elytra in males and convex elytra in females (Fig. 21 C, E View Figure 21 ) [convex elytra and elytral apex not visible in dorsal views in both sexes of B. choui sp. nov. (Fig. 5 C, E View Figure 5 )], and widened apex of aedeagus (Fig. 8 C View Figure 8 ) [parallel-sided aedeagus in B. choui sp. nov. (Fig. 6 C View Figure 6 )]. Adults of B. chungi sp. nov. are not separable from those B. tsoui sp. nov. by external morphology but the aedeagus of B. chungi sp. nov. (Fig. 8 C View Figure 8 ) is much wider than that of B. tsoui sp. nov. (Fig. 22 C View Figure 22 ).

Description.

Male. Length 1.95–2.32 mm, width 0.79–0.91 mm. General color metallic dark bronze; legs yellowish but femora of hind legs darkened. Antenna (Fig. 8 A View Figure 8 ) 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: 0.8: 0.7: 0.7: 0.8: 0.7: 0.6: 0.9; ratio of length to width of antennomeres I – XI 2.3: 2.1: 2.7: 2.9: 3.3: 2.6: 2.2: 2.4: 2.0: 1.9: 2.3. Pronotum 1.10–1.12 × wider than long; lateral margins slightly rounded, anterolateral angles separated from lateral margins by weak emarginations, slightly narrowed basally, distance between anterolateral angles 1.16–1.20 × wider than basal margin. Elytra 1.57–1.60 × longer than wide; lateral margins rounded, widest at basal 1 / 5, apically and strongly narrowed, apex truncate but divergent; dorsoventrally flattened, apex visible in dorsal view; disc with longitudinal lines of extremely coarse punctures and distinct longitudinal grooves along punctures, punctures and grooves apically abbreviated from apical 1 / 3. Tarsomeres I of front and middle legs slightly swollen. Aedeagus (Fig. 8 C, D View Figure 8 ) elongate, 4.4 × longer than wide; widest at apical 1 / 5, apically narrowed towards apex, apex widely rounded, basally widened near apical 2 / 5, then parallel-sided near base; dorsal opening starting from apical 1 / 7–9 / 20, tectum composed of three lobes, median lobe more basal relative to lateral lobes, apical margin truncate, mostly membranous; slightly curved in lateral view, apex moderately curved; ventral surface with membranous area as wide as dorsal opening, starting from apical 1 / 6–1 / 2.

Female. Length 2.11–2.45 mm, width 0.91–1.03 mm. Antennae similar to males, ratio of length of antennomeres I – XI to length of antennomere I (Fig. 8 B View Figure 8 ) 1.0: 0.6: 0.6: 0.6: 0.8: 0.7: 0.8: 0.7: 0.7: 0.7: 1.0; ratio of length to width of antennomeres I – XI 2.6: 2.0: 2.7: 2.7: 3.6: 2.7: 2.3: 2.3: 2.1: 2.0: 2.9. Elytra 1.49–1.57 × longer than wide; lateral margins rounded, widest at basal 1 / 5, apex truncate but divergent; dorsoventrally convex, apex not visible in dorsal view; disc with longitudinal lines of extremely coarse punctures and with distinct longitudinal grooves along punctures, punctures and grooves apically abbreviated from apical 1 / 3. Gonocoxae (Fig. 8 F View Figure 8 ) slender, connected 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. 8 E View Figure 8 ) weakly sclerotized apically, with several short setae at apical area, and some tiny setae at apical margin, spiculum extremely elongate. Spermathecal receptaculum (Fig. 8 G View Figure 8 ) 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.

Rosaceae : Rubus formosensis Kuntze ; R. taitoensis var. aculeatiflorus (Hayata) H. Ohashi & C. F. Hsieh (Fig. 9 A, B View Figure 9 ).

Etymology.

This new species is named for Yi-Ting Chung (鍾奕霆), the first member of TCRT to collect specimens.

Distribution.

Only known from the type locality in southern Taiwan (Fig. 7 View Figure 7 ).
