Head: vertex densely punctate, medial sulcus present; slightly depressed between eyes; frons punctate. Antenna: reaches to humerus; elongate; filiform; antennomeres 1-2 subequal in length, elongate; 3 elongate, cylindrical, 1½ length of 2; 4-5 subequal in length, expanding to apex, each ½ length of 3; 6-10 transverse, subequal in length, each ¾ length of 5; 11 2 × length of 10, pointed at apex; 1-2 punctate, each puncture with pale seta; 3-11 hirsute. Pronotum: transverse; subconvex; lateral margin straight for basal ¾ then rounding to anterior angle, margined; anterior angle with obtuse tooth; posterior angle acute; anterior margin weakly emarginate behind head; surface irregularly punctate; basal impression absent; pronotal length 1.0 mm; pronotal width 1.1-1.2 mm. Scutellum: pentagonal; micropunctate. Elytron: lateral margin straight, margined; exterior apical angle rounded, margined; apical margin rounded, margined; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; declivity absent; moderately punctate- striate; puncture rows converge and untie apically; rows 4-7 irregularly interrupted basally; elytral length 3.2 mm; elytral width 1.8-1.9 mm. Venter: pro-, meso-, and metasterna punctate, glabrous; suture between abdominal sterna 1 and 2 complete; abdominal sterna punctate laterally, glabrous, last sternite with pale white setae, apical margin rounded in male, emarginate in female.

Etymology.

From interruptum (Latin) for the interrupted elytral puncture rows at base. The name is feminine.

Diagnosis.

This species is similar to Cephaloleia eumorpha and Cephaloleia postuma . It can be distinguished by antennomere 1 being subequal in length to 2 and by lacking a V-shaped depression basally on the pronotum.

Host plant.

Adults have been collected off Costus sp. ( Costaceae ). The name is feminine.

Distribution.

Costa Rica.
