Cephaloleia halli Uhmann, 1951a Fig. 156

Cephaloleia halli Uhmann 1951a: 69. Uhmann 1957b: 20 (catalog); Gaedike and Döbler 1971: 350 (types); Staines 1997 b: 413 (Uhmann species list).

Description.

Elongate; subparallel; subconvex; shining; reddish-brown; eyes and apical antennomeres darker. Head: vertex impunctate, medial sulcus becomes carina between antennal bases; frons impunctate, not projecting; depressed between eyes. Antenna: as long as head and pronotum combined; slender; antennomere 1 slightly incrassate, longer than 2; 2-3 cylindrical, elongate, subequal in length to 3; 4-10 transverse, subequal in length; 11 longer than 10, rounded at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: quadrate; lateral margin straight for basal 4/5 then angulate to anterior angle, canaliculate; anterior angle angulate, produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex, nearly impunctate; surface sparsely punctate; basal impression absent; pronotal length 1.1-1.3 mm; pronotal width 1.2-1.4 mm. Scutellum: pentagonal, impunctate. Elytron: lateral and apical margins smooth; lateral margin straight, margined; apex rounded; sutural angle with minute tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, rows confused apically; elytral length 3.5-3.9 mm; elytral width 1.4-1.8 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin truncate in female, emarginate in male. Leg: slender; sparsely punctate; tibia with fringe of setae on inner margin of apex. Total length: 5.0-5.4 mm.

Diagnosis.

This species is similar to Cephaloleia apicicornis , Cephaloleia corallina , Cephaloleia ochra sp. n., and Cephaloleia proxima . It can be distinguished by the pronotum lacking a transverse basal impression, by the paler basal antennomeres, by the meso- and metaserna being punctate laterally, by the vertex of the head being depressed between the eyes, by antennomere 2 being longer than 1, and by the anterior angle of the pronotum being angulate.

Distribution.

Brazil (Bahia, Parana, Rondonia), Ecuador.
