Type specimens. Holotype male (?): Costa Rica, Cartago Prov., 11–18 km N Pavones, I-14 -[19]89, F. Hovore, coll. Holotype deposited in CASC. Paratype: 1, Costa Rica, Cartago Prov., 8 km N Pavones, 26 May 1985, F. T. Hovore, coll. Paratype deposited in WFBM.

Diagnosis. Readily separable from other small Cymatodera species exhibiting obovate “brachypterous type ” elytra by its coarsely punctate elytra, with punctures arranged in striae and strial interstices elevated into longitudinal carinae. Of further diagnostic significance, the elytral pattern is distinct ( Fig. 65) and the eyes are quite small.

Description. (Holotype). Length: 5.80 mm. Form: small, macropterous, but exhibiting typical obovate “brachypterous” shape. Color: yellow testaceous to reddish, elytra with a pair of oblique brownish antemedian maculae, and a dark brown postmedian elytral fascia ( Fig. 65), the fascia broad, darker and more defined than the maculae, narrowing laterally but complete to lateral margins. Head: measured across eyes, wider than pronotum; eyes small, elongate, with coarse ommatidia; antennae attaining posterior margin of pronotum when laid alongside; surface densely but shallowly rugulose–punctate; vestiture dense but inconspicuous, comprised of testaceous, suberect setae of moderate length. Pronotum: elongate (ratio of length to width 14:9); anterior depression distinct, narrowly U–shaped at middle; subbasal tumescences prominent; surface shining, sparsely, shallowly, very finely punctulate; vestiture moderate, inconspicuous, mostly composed of suberect setae with an intermingling of somewhat longer, erect setae. Elytra: obovate; humeri reduced; anterior margin only slightly broader than pronotum at posterior margin; sides expanded posteriorly; posterior 1/3 of each elytron broadly arcuately convergent to separately rounded, slightly dehiscent apices; surface very coarsely, serially punctate, with punctures lozenge–shaped, becoming shallow posteriorly; each elytron with a rather sharply crested interpunctual carina on disk, extending from near anterior margin longitudinally to posterior 1/3; adjacent interpunctual areas subcarinate. Metaventrite: shining, broadly sulcate posteriorly, without tubercles. Abdomen: surface shining, sparsely, finely punctulate, sparsely setose; ventrite 5 with posterior margin feebly, arcuately emarginate; ventrite 6 arcuate posteriorly, conjointly rounded with hind margin of tergite 6. Legs: all femora expanded distally.

Variation. The single paratype specimen has the antemedian elytral maculae darker than in the holotype.

Etymology: The specific epithet is a patronymic honoring Ryan Wilson, in recognition of his, and the Van de Kamp and Frank families’ support for my studies in the taxonomy of New World Cleridae .

Distribution. Known only from the vicinity of Pavones, Cartago Province, Costa Rica.
