Description.

Suboblong; small; subconvex; head and pronotum black; legs and apex of abdomen red; elytra testaceous with black macula at base near humerus, a second macula near basal margin approaching suture, and a medial black shallow V-shaped transverse band from suture to near lateral margin; antennae yellowish-brown. Head: vertex densely punctate, medial sulcus absent; frons not projecting; depressed between eyes. Antenna: reaches beyond humerus; slender; antennomeres 1-2 robust, elongate, cylindrical, 1 longest; 3-5 elongate, cylindrical, decreasing in length; 6-10 transverse, decreasing in length; 11 2 × length of 10, acutely pointed at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: quadrate; lateral margin straight for basal 4/5 then rounding to anterior angle, margined; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; disc subconvex; surface coarsely, irregularly punctate; transverse basal impression present medially; pronotal length 0.8-1.0 mm; pronotal width 0.9-1.1 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; coarsely punctate-striate; elytral length 2.7-3.1 mm; elytral width 1.3-1.5 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin subtruncate in male, rounded in female. Leg: slender; punctate; femur and tibia with row of setae on inner margin; tibia with fringe of setae on inner margin of apex. Total length: 3.9-4.3 mm.

Diagnosis.

This species is similar to Cephaloleia uniguttata . It can be distinguished by the totally black pronotum and by the elytra with a black humeral and scutellar macula basally and an irregular transverse band from the suture to the lateral margin.
