Jang Description Body length 10-14 mm (Fig. 1 A and B). Head black, minutely and densely punctuated with sparse golden setae, frons with short, but distinct longitudinal median suture. Antennae black, slightly shorter than body length in male, slightly longer than half of body length in female. Pronotum black in male, orange in female, with two longitudinal row of punctuations present medially, moderately pubescent. Prosternum black in male, orange in female, anteriorly with shallow transverse groove and with pale setae, prosternal process well-developed with apex widened. Abdomen orange in female, dark brown with brighter posterior segments in male, sparsely pubescent. Scutellum almost semicircular, black in male, orange in female. Elytra metallic black, almost half as long as body length, narrowed posterolaterally with somewhat rounded and unarmed apex. Legs orange with distal half of femora black, moderately pubescent on fore- and mid-legs, densely pubescent with long setae on hind legs, hind femora distinctly swollen. Tegmen apically blunt with short incision on middle, parameres indistinct, apex with long and dense setae (Fig. 1 C). Penis bullet-like with sharp apex, almost as long as dorsal struts (Fig. 1 D). Ovipositor gradually and slightly narrowed towards apex, slightly bilobed at apex, apically hairy with short styli (Fig. 1 G). Distribution Korea (new record), China, Japan, Taiwan. Notes Emergence begins in early July in the southern part of the Korean Peninsula. Beetles are most active in warm clear weather and visit the male flower of Mallotus japonicus (Thunb.) Muell. Arg. The population size in the site seems remarkably high as 139 beetles were caught in a few hours. The number of males visiting flowers is approximately ten times larger than that of females.
