Description.

Elongate; subparallel; subdepressed; reddish-brown; antennae (except basal 2 antennomeres) and eyes black; venter and legs paler. Head: vertex finely, irregularly punctate; medial sulcus present; not depressed between eyes; frons punctate, not projecting. Antenna: reaches to humerus; antennomere 1 subincrassate, 2 × length of 2; 2-4 cylindrical, 3 slightly longer than 2, 4 subequal in length to 2; 5-10 transverse, subequal in length; 11 2 × length of 10, rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin straight, divergent for basal ¾ then rounding to anterior angle, canaliculate; anterior angle rounded; posterior angle acute; anterior margin emarginate behind head; disc depressed; surface sparsely, irregularly punctate; basal impression absent; pronotal length 1.3-1.4 mm; pronotal width 1.7-1.8 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, margined; apical margin smooth, narrowly margined; sutural angle without tooth; humerus rounded, slightly produced; slightly constricted behind humerus; moderately punctate-striate, punctures obovate, scutellar row long, rows confused at apex; elytral length 4.0-4.2 mm; elytral width 2.3-2.4 mm. Venter: pro-, meso-, and metasterna im punctate medially, punctate laterally; prosternum with pale seta in each puncture; abdominal sterna finely punctate, each puncture with pale seta; sutural between sterna 1 and 2 obsolete medially; apical margin of last sternite emarginate medially in male, sinuate in female. Leg: robust; punctate; tibia with fringe of setae on inner apical margin. Total length: 6.2-6.6 mm.

Etymology.

From conformis (Latin) meaning like or resembling, since the species resembles Cephaloleia congener and Cephaloleia sallei . The name is a noun in apposition.

Diagnosis.

This species is similar to Cephaloleia calathae and Cephaloleia erichsonii . It can be distinguished by the elytra lacking a sulcus on the humeral callus, by antennomere 1 being clavate and twice the length of 3, and by the elytral punctures not being larger on the disc.

Host plant.

Adults have been collected off Calathea sp., Cephaloleia guzamanioides LB Sm and Idrobo ( Marantaceae ).

Distribution.

Costa Rica.
