Cephaloleia obsoleta Weise. Uhmann 1957b: 22 (catalog).

Description.

Elongate; subparallel; subconvex; shining black, head with bluish or greenish metallic sheen. Head: vertex smooth, faint medial sulcus present; frons not projecting; depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1-2 transverse, subequal in length; 3 as long as 1-2 combined, elongate; 4 elongate, ¾ length of 3; 5-10 transverse, subequal in length, each ¾ length of 4; 11 2 × length of 10, pointed at apex; 1-4 punctate with scattered setae; 5-11 setose. Pronotum: quadrate; lateral margin straight, slightly divergent then rounding to anterior angle, slightly canaliculate; anterior angle rounded, not produced; posterior angle acute; anterior margin weakly emarginate behind head; disc subconvex; surface finely, sparsely punctate; basal impression absent; pronotal length 1.2-1.4 mm; pronotal width 1.2-1.4 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded, finely serrulate; sutural angle with small tooth; humerus rounded, not produced; slightly constricted behind humerus; finely punctate-striate, punctures larger and deeper apically, rows converge and unite apically; elytral length 4.0-4.4 mm; elytral width 1.5-1.7 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna sparsely, irregularly punctate, each puncture with white seta; suture between sterna 1 and 2 complete. Leg: slender; punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 5.3-5.8 mm.

Diagnosis.

This species is similar to Cephaloleia funesta and Cephaloleia impressa . It can be distinguished by the vertex of the head having a medial sulcus, by the elytra being regularly convex, and by antennomere 1 being shoter than 3.
