Description.

Elongate; parallel-sided; subdepressed; head black, mouthparts yellowish; antenna black except for apex of antennomere 11 (some specimens with antennomeres 1-2 paler); pronotum yellow; scutellum black; elytra black with wide longitudinal yellow vitta from humerus to near apex; venter with pro-, meso-, and metasterna fuscous, abdominal sterna yellowish medially darker laterally; legs yellow, joints and tarsi darker. Head: vertex striate-punctate, with wide medial sulcus, not depressed between eyes; slight swelling present between antennal bases; clypeus punctate. Antenna: reaches to humerus; antennomere 1 elongate, as long as 2 to 4 combined, incrassate, expanding apically; 2-3 subequal in length, triangularly produced; 4 triangularly produced, shorter than 3; 5-10 cylindrical, increasing in length; 11 longer than 10, pointed at apex; 1-2 punctate; 3-11 punctate, each puncture with dark seta. Pronotum: transverse, widest at base; lateral margin smooth, margined; anterior angle rounded; anterior margin straight; posterior angle subacute; posterior margin bisinuate; disc flattened; surface sparsely, irregularly punctate; pronotal length 1.1-1.3 mm; pronotal width 1.4-1.6 mm. Scutellum: elongate, triangular, punctate. Elytron: lateral margin straight, smooth, margined; rounding to sutural angle; humerus rounded, not produced; slightly constricted behind humerus; surface faintly punctate-striate, declivity present beginning at puncture row 7, without carina; elytral length 5.3-5.7 mm; elytral width 2.0-2.3 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between abdominal sterna 1 and 2 complete; apical margin of last sternite truncate weakly notched in male, weakly rounded in female.

Etymology.

Named for W. John Kress in recognition of his many contributions to the understanding of the ecology and evolution of plant animal interactions, in particular between plants from the order Zingiberales , their pollinators and Cephaloleia insect herbivores. Also in recognition of his mentorship of new generations of researchers. The name is a noun in apposition.

Diagnosis.

Cephaloleia kressi sp. n. is most similar to Cephaloleia adusta Uhmann. It can be distinguished by the following combination of characters: vertex of head striate-punctate; vertex of head with wide medial sulcus; frons not projecting; elytra with sutural angle rounded; and elytral puncture rows being visible after middle.

Host plant.

Heliconia lankesteri Standl. ( Heliconiaceae ).

Distribution.

Costa Rica.
