Description.

Oval; subdepressed; shining; testaceous; legs yellow, darker at tibio-femoral joint; antennomeres 1-2 black, 3-11 brown; head, meso-, and metasterna black; pronotum brownish-black; scutellum testaceous; elytra yellowish with black vitta from scutellum extending down suture ⅔ length of elytra; venter testaceous, abdominal sternite 1 darker. Head: vertex strongly, densely punctate, without medial sulcus; projection present between antennal bases; frons not projecting; depressed between eyes. Antenna: slightly longer than head and pronotum combined; slender; antennomeres 1-2 robust, cylindrical; 3-4 cylindrical, subequal in length, each shorter than 2; 5-10 transverse, decreasing in length, each shorter than 4; 11 longer than 10, acutely pointed at apex; 1-2 strongly punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle, slightly canaliculate; anterior angle obtuse, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; with smooth longitudinal band medially; surface irregularly punctate, less punctate laterally; basal impression absent; pronotal length 1.2-1.4 mm; pronotal width 1.5-1.7 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, slightly laminate; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate; elytral length 3.7-4.1 mm; elytral width 2.1-2.5 mm. Venter: pro- and mesosterna densely punctate; metasternum impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; apical margin of last sternite emarginate medially in male, rounded in female. Leg: short; robust; punctate, each puncture with pale seta; tibia with fringe of setae on inner margin of apex. Total length: 5.3-5.6 mm.

Diagnosis.

This species is similar to Cephaloleia deficiens , Cephaloleia discoidalis , Cephaloleia dorsalis , Cephaloleia linkei , and Cephaloleia suturalis . It can be distinguished by the dark pronotum and by antennomeres 1 and 2 being robust.
