Description.

Small; stubby; subdepressed; yellowish-brown, antennomere 1 yellowish-brown, 2-10 darker, 11 dark basally, paler apically. Head: vertex strongly punctate, medial sulcus absent; frons punctate, not produced; keel absent between antennal bases; depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1-2 cylindrical, elongate, subequal in length; 3 cylindrical, elongate, 2 × length of 2; 4-5 cylindrical, elongate, decreasing in length; 6-10 transverse, subequal in length, each ¾ length of 5; 11 2 × length of 10, pointed at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin arcuate from base to anterior angle, finely crenulate, margined; anterior angle obtuse, slightly projecting; posterior angle acute; anterior margin emarginate behind head; disc subconvex; surface with disc irregularly sparsely punctate, densely coarsely punctate laterally; basal impression absent; pronotal length 0.9 mm; pronotal width 1.6 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, nearly smooth, finely margined; apex rounded, smooth; sutural angle without tooth; humerus rounded, not produced; constricted behind humerus; moderately irregularly punctate-striate, row 10 removed from lateral margin; elytral length 2.9 mm; elytral width 1.7 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; apical margin of last sternite concave in female. Leg: slender; punctate, each puncture with pale seta; tibia with fringe of setae on inner apical margin. Total length: 3.9 mm.

Etymology.

From crenulatum (Latin) meaning minutely emarginate for the finely emarginate lateral margin of the pronotum. The name is feminine.

Diagnosis.

This species is similar to the pale form of Cephaloleia steinhauseni . It can be distinguished by the crenulate lateral margin of the pronotum, by the punctate vertex of the head, and by antennomere 1 and 2 being subequal in length.

Distribution.

Ecuador.
