Etymology The specific epithet is derived from Latin and refers to the stout penis. Fig. 13. Chilocorus hupehanus Miyatake, 1970 . a . Dorsal view. b . Lateral view. c . Frontal view. d .

TL: 3.41 mm , TW: 2.93 mm , TH: 1.77 mm , TL/TW: 1.16, PL/PW: 0.51, EL/EW: 1.02. BODY. Roundish, strongly convex. Head, antenna and mouthparts brown-black, sparsely covered with short, greyish pubescence. Pronotum and scutellum black. Elytra black with a pair of oblong, orange spots, situated at centre, about ½ elytra width ( Fig. 14 a–c). Underside black except abdomen brown, sparsely covered with short, greyish pubescence. Head relatively large, 0.60 × as wide as pronotum, punctures on frons large and densely distributed, 1.0–2.0 diameters apart, surface polished between punctures. Eyes subtriangular, densely faceted, interocular distance 0.55 × as wide as head ( Fig. 14c ). Pronotum 0.59 × as wide as elytra, pronotal punctures moderately large and sparsely distributed, smaller than those on head, 2.0–3.5 diameters apart, surface polished between punctures. Punctures on elytra fine and sparsely distributed, 3.0–4.0 diameters apart, smaller than those on pronotum. Prosternal process moderate broad, slightly expanded to apex. Abdominal postcoxal lines incomplete, reaching posterior margin of abdominal ventrite 1 and running along posterior margin and almost reaching lateral margin. Posterior margin of male abdominal ventrite 5 truncate and 6 broadly rounded ( Fig. 14d ). MALE GENITALIA. Penis stout and simple, penis capsule with short outer arms and long inner arms, apex of penis truncate and membranous around at ½ to apex ( Fig. 14 e–f). Tegmen distinctly stout with penis guide subtriangular, widest at base, gradually converging to blunt apex in ventral view and widest at base, gradually converging to blunt apex in lateral view. Parameres distinctly longer than penis guide Fig. 14. Chilocorus strenotubus Li & Wang sp. nov. , holotype a . Dorsal view. b . Lateral view. c . Frontal view. d . Abdomen. e . Penis. f .
