Cephaloleia dilatata Uhmann 1948a: 220. Uhmann 1957b: 17 (catalog), 1961b: 6 (noted), 1964a: 403 (catalog); Gaedike and Döbler 1971: 347 (types); Staines 1997 b: 413 (Uhmann species list).

Description.

Elongate-oval; flattened; somewhat shining; head, antenna, pronotum, and legs black; elytra metallic blue; venter with prosternum brown. Head: vertex sparsely punctate, with medial sulcus; frons with small tubercle, not projecting; slightly depressed between eyes. Antenna: as long as head and pronotum combined; slender; antennomeres 1-3 elongate; 1 longest; 2-3 subequal in length; 4-10 transverse, subequal in length, each shorter than 3; 11 2 × length of 10, rounded at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse; lateral margin straight and divergent for basal ¾ then rounding to anterior angle, canaliculate; anterior angle angulate, not produced; posterior angle acute; anterior margin emarginate behind head; disc transversely convex, virtually impunctate; surface moderately punctate laterally; basal impression absent; pronotal length 1.0-1.2 mm; pronotal width 1.6-1.8 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded, smooth; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; subconvex; shallowly punctate-striate; elytral length 4.0-4.2 mm; elytral width 2.2-2.4 mm. Venter: prosternum punctate medially, alutaceous laterally; meso- and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin bisinuate. Leg: robust; punctate; femur and tibia with pale seta in each puncture; tibia with fringe of setae on inner margin of apex. Total length: 5.2-5.6 mm.

Diagnosis.

This species is similar to Cephaloleia caeruleata and Cephaloleia diplothemium . It can be distinguished by the cylindrical antennomere 1 which is longer than 3, by the elytral punctures being the same size laterally, and by the prosternum being alutaceous laterally.

Distribution.
