Cephaloleia weisei Staines 1996: 71.

Description.

Small; subovate; subdepressed; head, antennomeres 1-2, pronotum, and basal ½ of elytra yellowish; eyes, antennal antennomeres 3-11, and apical ½ of elytra black; venter and legs reddish-yellow. Head: vertex alutaceous, medial carina present; frons not projecting; depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1-2 elongate, cylindrical, subequal in length; 3-10 transverse, subequal in length; 11 pointed at apex, subequal in length to 1 or 2; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin straight for basal ¾ then rounding to anterior angle in male, female evenly arcuate, narrowly margined; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; disc subconvex; punctures large, shallow, sparse; basal impression absent; pronotal length 0.7-0.9 mm; pronotal width 1.3-1.6 mm. Scutellum: pentagonal, alutaceous. Elytron: lateral margin slightly expanding to middle then rounding to apex, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, rows obsolete on apical ⅓, row 10 removed from margin; elytral length 2.7-3.0 mm; elytral width 1.3-1.9 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; su ture between sterna 1 and 2 obsolete medially; last sternite with apical margin emarginate medially in male, truncate in female. Leg: slender; punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 3.6-4.1 mm.

Diagnosis.

This species is similar to Cephaloleia trimaculata . It can be distinguished by antennomeres 1 and 2 being subequal in length, by the uniformly punctate pronotum, and by the elytral puncture rows being obsolete apically.
