Cephaloleia diplothemium Uhmann 1951a: 70. Uhmann 1957b: 18 (catalog); Gaedike and Döbler 1971: 347 (types); Staines 1997 b: 413 (Uhmann species list).

Description.

Elongate-ovate; flat; head and pronotum black with weak metallic sheen; elytra clearly metallic-green; mouthparts and antennae brownish; legs and sides of abdomen pitch-brown. Head: vertex finely punctate between the eyes, with faint medial carina and fine longitudinal keel between antennae; eyes strongly convex; frons impunctate, not projecting; slightly depressed between eyes. Antenna: slightly longer than head and pronotum combined; slender; antennomere 1 elongate, only slightly thicker than the others, obliquely truncate apically; 2 less than ½ length of 1, subglobose; 3 as long as 1, weakly conical; 4-10 each shorter than 3, cylindrical, elongate, 11 slightly flattened, 2 × length of 10, pointed at apex; 1-2 coarsely, densely punctate; 3-11 finely pubescent. Pronotum: 1½ times as wide as long; lateral margin diverging from the base then broadly rounding to anterior angle, slightly canaliculate; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; with punctures very fine medially, denser and coarser laterally; basal impression absent; pronotal length 0.6-0.8 mm; pronotal width 1.0-1.3 mm. Scutellum: pentagonal, micropunctate. Elytron: lateral margin straight, smooth, finely margined; apex rounded; sutural angle truncate, without tooth; humerus rounded, not produced; slightly constricted behind humerus; scutellar row long; puncture rows 1-6 are very fine; interspaces flat, 9 slightly raised behind the humerus; pygidium densely punctate, with very weak impression; elytral length 2.2-2.6 mm; elytral width 1.0-1.4 mm. Venter: epipleuron, pro-, and metasterna finely punctate; mesosternum impunctate; abdominal sterna finely punctate, each puncture with pale seta; suture between sterna 1 and 2 totally obsolete; male with apical margin of last sternite emarginate medially, female rounded, entire. Legs: slender; punctate; femur robust; tibia with fringe of setae on inner margin of apex. Total length: 3.0-3.5 mm.
