Description.

Elongate; subparallel; subdepressed; head (except yellow frons), antennae (except yellow basal antennomere), and scutellum black; pronotum yellowish with dark medial longitudinal macula on anterior margin; elytra black with yellow vitta; venter with pro-, meso-, and metasterna yellow medially, black laterally; abdominal sterna yellow; leg with femur yellow, darker at apex; tibia dark at base and apex, rest yellow; tarsi dark. Head: vertex sparsely punctate, medial sulcus absent; frons not projecting; slightly depressed between eyes Antenna: reaches to humerus; robust; antennomere 1 elongate, compressed laterally; 2-4 transverse, triangular; 5-10 transverse, subequal in length, each shorter than 4; 11 slightly longer than 10, rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: lateral margin straight then rounding to anterior angle, margined; anterior angle oblique, slightly produced; posterior angle rounded, slightly produced; anterior margin emarginate behind head; disc subconvex; surface impunctate; basal impression absent; pronotal length 1.1 mm; pronotal width 1.6 mm. Scutellum: triangular; micropunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, punctures obsolete apically; elytral length 4.9 mm; elytral width 2.1 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 bisinuate in male. Leg: slender; impunctate; tibia expanded to apex, with fringe of setae on inner margin of apex. Total length: 6.4 mm.

Diagnosis.

This species is similar to Cephaloleia ornatrix and Cephaloleia separata . It can be distinguished by the elytral puncture rows being nearly obsolete apically and by antennomere 1 being shorter than 2 to 4 combined.

Distribution.

Mexico.
