( Figs 12‒20 , 23, 24 , 28‒30 ) Diagnosis. The new species is close to B. ( C. ) championi ( Reitter, 1891 ) but can be distinguished by the following characteristics: pronotum widest at base, anterior angles sharp, and posterior angles rectangular, whereas in the latter, widest in the middle or before the middle, anterior angles acute, and posterior angles sharp or acute; elytra of the new species with incompletely line of punctures, whereas complete in the latter; the paramere distinctly constricted before the widest of base by the dorsal view, weakly highlight by the ventral view, whereas not constricted in the latter. Description. Length 11.1 mm , width 5.2 mm . Body brown with weak bronze shine; head and pronotum black-brown, legs, antennae, labial, maxillary palpi and abdomen puce; elytra with strong bronze shine. Male ( Figs 12–20 , 23 ). Anterior margin of clypeus straight, clypeofrontal suture slightly concave, densely covered with fine punctures. Frons weakly and arcuately convex, sparsely covered with fine punctures. Genae slightly convex, densely covered with punctures. Head densely punctate, covered with golden long setae. Eyes transverse, shallowly concave on anterior margin. Antennomeres II‒X long cylindrical. Ratio of length (width) of antennomeres II‒XI as follows: 17.9 (14.7): 47.1 (17.1): 29.6 (16.2): 32.4 (13.3): 30.2 (14.0): 33.7 (13.5): 32.9 (13.3): 30.1 (14.1): 31.5 (15.2). Figures 12–20.

Pronotum ( Fig. 12 ) sub-rectangular, 1.3 times as wide as long, 1.7 times as wide as head, widest at base. Ratio of pronotal width on anterior margin to the maximum width and to the width at posterior margin is 1.8: 2.5: 2.7. Lateral sides distinctly constricted anteriorly at apical 1/3. Anterior margin distinctly concave, posterior margin almost straight. Anterior angles acutangular and posterior angles rectangular. Anterior and posterior margins bordered near lateral sides, and lateral margin with complete edge; disc punctures large and dense, densely covered with dust-liked golden setae. Prosternal process weakly curved downwards, slightly sharp and rectangular at apex. Elytra oblong, 1.4 times as long as wide, 1.4 times as wide as pronotum; widest in the base; disc finely wrinkled, punctures large and sparse; lateral margin deeply depression, border visible in dorsal view only in the middle, combined with epipleura, reaching near sutural angle; humeri rounded, covered with dust-like golden setae. Profemur strong, sparsely covered with punctures and recumbent golden setae. Protibia gradually widened apically, inner side slightly curved, densely covered with recumbent short golden setae at apical 1/2; apex of ventral side without depression; outer side not blade-shaped. Protarsus distinctly widened apically; meso- and metafemora slender. Mesotibia gradually widened apically, densely covered with recumbent golden setae. Mesotarsus ( Fig. 16 ) not strongly widened apically, narrower than the apex of mesotibia. Metatarsus almost straight, densely covered with recumbent golden setae. Ratio of lengths (widths) of pro-, meso- and metafemora is 1.5 (0.7): 2.2 (0.5): 2.7 (0.4), respectively, that of tibiae ( Figs 13–15 ) is 1.7 (0.4): 1.6 (0.3): 2.4 (0.3); and ratio of width (length) of meso- and metatarsomeres I–IV ( Fig. 17 ), respectively, as follows: 25.2 (33.6): 31.5 (34.4): 28.0 (26.0): 22.0 (21.4), 21.1 (78.9): 15.0 (41.6): 15.0 (34.1): 12.3 (50.2). Abdomen sparsely covered with recumbent golden setae, anterior margin of visible sternum I wide and round, apical margin of visible sternum V wide and round, center of visible sterna I‒II flattened. Aedeagus ( Figs 18–20 ) length 1.5 mm , width 0.5 mm . Parameres widest at base, constricted nearly straight at anteriad, round and without sinuate at apex. Female ( Fig. 24 ). Body wider than male. Antennae shorter and reaching posterior to pronotum. Pronotum more transverse than male, approximately 1.3 times as wide as long. Pro- and mesotarsi simple. Body length 12.1 mm , width 6.1 mm .
