Caryopemon luteonotatus Pic, 1898:173.— Type locality: India .

MATERIAL EXAMINED

1 male, Xiaomengyang Village , Yunnan Province, China. 22.08°N, 100.90°E, alt. 850 m, 1-VIII-1957, Wang Shuyong [IOZ(E)1045488] .

DIAGNOSIS

Dimension. Body length (pronotum–elytra) 5.2–7.0 mm; width 2.6–3.0 mm.

Color. Integument black, antennal margin reddish; vestiture pale yellow, conspicuous on elytra, dorsal of hind femur, pygidium, and segmental venter ( Figs. 9 and 10 ), especially dense on segmental venter. Six pairs of spots on elytra as follows: 3 square close to anterior margin and suture; 3 round at center and on posterior margin. First sternite with brown hairs forming large spots in middle ( Fig. 10 ).

Head elongate; frontal carina present, hairless. Eyes rather flat, emarginate to 1/2 length of eye. Antennal articles: 1–3 subcircular, 4 and 5 isosceles right triangle, 6–11 pectinate. Pronotum subtrapezoidal, with many shallow pits, greatest width at base (W/L = 1.15), sides almost straight ( Fig. 9 ). Metasternal process strongly convex in lateral view. Elytra about 1.15 times longer than wide. Pygidium longer than wide. Hind femur strongly incrassate, pecten with 1 sharp spine with 2 gradually smaller, blunt denticles following, 3 spines before pecten; 1st spine small in middle of hind femur; other spines large and sharp between pecten and small spine ( Fig. 11 ).
