Description.

Narrowly elongate; subparallel; subdepressed; head and antennae (except for basal 2 antennomeres brownish) black, pronotum yellow (except for indistinct trilobed dark macula on anterior margin); elytra black with bright yellow longitudinal vitta medially on each elytron from base, narrowing behind, abbreviated near apex; scutellum and venter yellow. Head: vertex finely punctate, medial carina present, extending to between antennal bases; frons not projecting; depressed between eyes. Antenna: less that ½ body length; robust; antennomeres elongate; 1 subincrassate; 2 cylindrical, ½ length of 1, shortest; 3 subequal in length to 1; 4-10 decreasing in length, each shorter than 3; 11 2 × length of 10, broadly rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: quadrate; lateral margin straight then rounding to anterior angle, canaliculate; anterior angle rounded, slightly produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface deeply punctate, less dense on disc; basal impression absent; pronotal length 1.6-1.8 mm; pronotal width 2.0-2.2 mm. Scutellum: elongate; pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex subtruncate; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; flattened along suture; declivity beginning just behind humerus at puncture row 7 not edged with faint carina; moderately punctate-striate, punctures more impressed laterally, confused at apex; interspaces sulcate laterally, 3 costate for entire length; elytral length 5.8-6.2 mm; elytral width 2.2-2.6 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 entirely obsolete; last sternite with apical margin broadly emarginate, slightly produced medially in male, truncate in female. Leg: slender; punctate; tibia with fringe of setae on inner margin of apex. Total length: 7.7-8.1 mm.

Diagnosis.

This species is similar to Cephaloleia eximia and Cephaloleia saundersii . It can be distinguished by the suture between abdominal sterna 1 and 2 being obsolete medially and by the pro-, meso-, and metasterna being punctate.

Distribution.
