Glyphidocera dictionis , new species

(Figs. 75–77, 279, 312, Map 14)

Diagnosis.— Glyphidocera dictionis is similar to G. brumae but differs from the latter by having a smaller gnathos, a shorter apical furca of the valval costa, and a broader outer margin of the valval cucullus.

Description.— Head: Vertex and frontoclypeus pale brownish yellow; outer and inner surfaces of labial palpus pale brownish yellow; scape and flagellum of antenna pale brownish yellow; male 4th flagellomere dorsally protuberant and curved, forming a shallow concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a few setiform scales on apex of protuberance of 4th flagellomere; proboscis pale brownish yellow.

Thorax: Tegula and mesonotum pale brownish yellow. Legs pale brownish yellow. Forewing (Fig. 312): Length 6.3–7.5 mm (n = 10), pale brownish yellow intermixed with brown scales; costal margin and distal 1/4 brown intermixed with few pale brownish­yellow scales; cell with 2 large spots, 1 near middle, 1 near distal end [some specimens with spots faint or missing]; marginal spots present or absent. Undersurface pale brown except, costal margin pale brownish yellow. Hindwing: Grayish brown.

Abdomen (Fig. 75): Male with 2 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3, and two small, elliptical­shaped clusters of sex scales on dorsolateral surface of intersegmental area between terga 3–4.

Male Genitalia (Figs. 76–77): Uncus elongate, slightly constricted broadly near 1/3, apically rounded, abruptly dilated subapically, tapering to a short, narrowly rounded and setose apex; gnathos setose, protuberant, narrow throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a wide base, fusing near 2/3 length from posteroventral margin of tegumen to base of uncus; costa of valva broadly emarginate medially; apical furca acuminate, upturned; base of costa bearing a slightly downturned digitate process; sacculus twisted apically, constricting valva slightly before midlength, widened distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose, with outer margin short and slightly rounded; vesica sparsely denticulate, bearing a moderately large, crescent­shaped cornutus; cornutus dilated basally, exposing a hollow, basal cavity.

Female Genitalia (Fig. 279): Papillae anales elongate, slightly wider basally than apically; apophysis posterioris and apophysis posterioris about equal in length; eighth sternum narrower than eighth tergum; posterior margin of eighth sternum broadly rounded, anterior margin slightly emarginate; posterior margin of eighth tergun broadly emarginate, anterior margin broadly rounded; antrum subtriangular, greatly enlarged posteriorly from a constricted anterior part, posterior margin nearly straight, posterolateral margin angular; anterior part of antrum with a pair of elongate, spinelike processes inside cavity formed from outer wall; ductus bursae short; corpus bursae sparsely denticulate posteriorly, slightly enlarged anteriorly; inception of ductus seminalis widened basally from posterior part of corpus bursae, about 8­coiled, each coil gradually decreasing in diameter for base to apex; ductus seminalis with a short, basal, internal, 4­coil support on side opposite an elongate, internal plate.

Distribution ( Map 14): Glyphidocera dictionis is known from five collecting sites in Costa Rica; two nearby sites in the north­west along the Cordillera de Guanacaste, two sites in north­central part of the country along the Caribbean Coast, and a single site in the south­east along the Pacific Coast.

Etymology: The specific epithet dictionis is derived from the Latin “diction,” meaning speech.
