Diagnosis.

Adults of B. houjayi sp. nov. are not separable from those of B. wusheensis sp. nov., B. yuae sp. nov., B. jungchani sp. nov., and B. huangi sp. nov. that are characterized by truncate elytral apices based on external morphology except for the aedeagus (see below). However, these species can be recognized by their allopatric distributions [ B. houjayi sp. nov. inhabits high mountains in Chiayi, Ilan, Hualien, and Nantou counties, B. wusheensis sp. nov. in lowlands of Nantou County, B. yuae sp. nov. in lowlands of Taipei and New Taipei Cities, and Ilan County, B. jungchani sp. nov. in high mountains of Taichung and Miaoli counties, B. huangi sp. nov. in lowlands of Miaoli County and high mountains in Hsinchu and Taoyuan counties (Fig. 13)]. Aedeagal shapes are diagnostic [widely rounded apex of aedeagus in B. houjayi sp. nov. (Fig. 11 C), apically tapering aedeagus from apical 1 / 5 in B. wusheensis sp. nov. (Fig. 23 C), rounded apex of aedeagus with truncate process at middle of apical margin in B. yuae sp. nov. (Fig. 26 C), subapically tapering apex of aedeagus in B. jungchani sp. nov. (Fig. 15 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 1.63–1.92 mm, width 0.82–0.94 mm. General color metallic dark bronze (Fig. 10 A – C); antennae yellowish brown but six apical antennomeres darker; legs yellowish but femora of hind legs darkened. Antenna (Fig. 11 A) 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: 0.6: 0.6: 0.6: 0.6: 0.6: 0.6: 0.8; ratio of length to width of antennomeres I – XI 2.6: 2.1: 2.2: 2.3: 2.6: 2.2: 2.0: 1.8: 1.7: 1.6: 2.3. Pronotum 1.22–1.30 × wider than long; lateral margins slightly rounded, anterolateral angles separated from lateral margins by weak emarginations, slightly narrowed basally, distance between anterolateral angles 1.10–1.17 × wider than basal margin. Elytra 1.28–1.34 × 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 apically abbreviated, ridges present between longitudinal grooves and apically abbreviated from basal 1 / 3. Tarsomeres I of front and middle legs slightly swollen. Aedeagus (Fig. 11 C, D) elongate, 5.7 × longer than wide; lateral margins subapically parallel, then slightly widened basally, widest at basal 1 / 3, apex widely rounded; dorsal opening starting from apical 1 / 10–2 / 5, tectum membranous; moderately curved in lateral view; ventral surface with membranous area narrower than dorsal opening, starting from apical 1 / 20–1 / 3.

Females (Fig. 10 D – F). Length 1.79–2.21 mm, width 0.96–1.10 mm. Antennae similar to males, ratio of length of antennomeres I – XI to length of antennomere I (Fig. 11 B) 1.0: 0.6: 0.5: 0.5: 0.6: 0.5: 0.6: 0.6: 0.6: 0.6: 0.8; ratio of length to width of antennomeres I – XI 2.9: 2.2: 2.5: 2.2: 3.0: 2.3: 2.2: 1.8: 1.8: 1.7: 2.4. Elytra 1.26–1.38 × longer than wide; lateral margins rounded, widest at basal 1 / 5, apex truncate; dorsoventrally convex, elytral apex not visible in dorsal view; disc with longitudinal lines of fine punctures, and distinct longitudinal grooves along punctures apically abbreviated from apical 1 / 3, ridges present between 2 nd and 3 rd, 4 th and 5 th longitudinal grooves and apically abbreviated from basal 1 / 3. Gonocoxae (Fig. 11 F) slender, connected from basal 1 / 5 to base; each gonocoxa with seven long setae and one tiny seta from apical 1 / 5 to apex, subapically slightly curved. Ventrite VIII (Fig. 11 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. 11 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.

Longitudinal ridges on elytra present in most individuals from Alishan (Fig. 12) but absent in specimens from other areas.

Food plants.

Rosaceae: Rubus lambertianus Ser. and R. croceacanthus H. Lév.; Polygonaceae: Persicaria thunbergia Sieb. et Zucc. and P. chinense L. (Fig. 9 C).

Etymology.

This new species is named for Hou-Jay Chen (陳厚潔), the first member of TCRT to collect specimens.

Distribution.

This species is widespread in mountainous areas of south and central Taiwan (Fig. 13).
