(Fig. 65)
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.
