Diagnosis.— Glyphidocera eminetiae is similar to G. gemmae but differs from the latter by having an upturned apical furca of the valval costa, a more angular distal part of the valva, and a smaller apical cornutus of the aedeagal vesica.

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

Thorax: Tegula and mesonotum pale brownish yellow intermixed with few brown scales. Legs pale brownish yellow intermixed with few brown scales. Forewing (Fig. 317): Length 6.2–7.6 mm (n = 11), pale brownish yellow intermixed with brown scales; costa and distal 1 / 4 darker patterned; cell with 2 large spots, 1 near middle, 1 near distal end [some specimens with some or all spots absent]. Undersurface brownish gray. Hindwing: Pale brownish gray.

Abdomen (Fig. 90): Male with 3–4 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 membrane between terga 3–4.

Male Genitalia (Figs. 91–92): Uncus elongate, wide basally, broadly constricted near 2 / 3, apically widened, tapering to an acuminate and setose apex; gnathos sparsely setose, protuberant, narrow throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing about 2 / 3 distance from posteroventral margin of tegumen, gradually widening dorsally to base of uncus; costa of valva nearly straight from base to subapical part; apical furca, acuminate, and slightly upturned; base of costa bearing a slanted digitate process; sacculus twisted apically, constricting valva near midlength, distoventrally forming a broadly rounded cucullus; cucullus membranous and setose; vesica sparsely spinulate, bearing a short, conical, apical cornutus; cornutus shortened on one side, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution (Map 17): Glyphidocera eminetiae is known from five collecting sites in northern Costa Rica; two nearby sites in the north­west along the Cordillera de Guanacaste, two nearby sites in the north­central part of the country along the Cordillera Central, and one site half way between Tortuguero and Barra del Colorado.

Etymology: The species epithet eminetiae is derived from the Latin “eminetia,” meaning prominence.
