Diagnosis. C. costaricae can be distinguished by its whitish forewing ground colour and brown markings. It is related to C. chrysopyla , but C. costaricae has a much broader uncus, a shorter aedeagus, and a weakly convex posterior edge of the sterigma.

Description. Wing span 19 mm. Male: Head and thorax cream, labial palpus and thorax with brown-grey markings. Forewing not expanding terminad; apex rounded; costa almost straight; costal fold slender, reaching 1/3 of costa. Ground colour whitish, sprinkled brown; greyish brown strigulae in basal and posterior parts of wing; brown triangular postbasal blotch and median fascia forming a pale dorsal blotch; terminal and apical marks weak. Cilia blackish brown in apical area, much paler medially, whitish at tornus. Hindwing whitish, brownish grey in apical part with darker strigulae; cilia whitish, brownish grey in apical third. Genitalia ( Fig. 1 ) with uncus very broad, fairly short, convex apically; socius weakly expanding posteriorly; basal half of valva broad, neck short; sacculus angulate; cucullus moderately broad; aedeagus rather broad, short.

Female: Forewing ground colour pale, markings dark brown, strigulation rather weak except for basal area. Genitalia ( Fig. 13 ) with apophyses fairly broad; posterior edge of sterigma slightly convex; folds of subgenital sterite broad postmedially; sclerite of antrum about one-half as long as cingulum; blades of signa slender.

Holotype male: " Costa Rica, [San José], Cerro [de] la Muerte, 5–7.VIII.1981, 3100 m, V. O. Becker Col; Col. Becker 45030"; GS 839 WZ. Two paratypes with similar label data, female with GS 838 WZ.

Etymology. The name refers to the country of origin.
