Glyphidocera orae , new species

(Figs. 24–26, 295, Map 5 )

Diagnosis.— Glyphidocera orae appears most similar to G. o p e r a e but differs from the latter by having a smaller gnathos, a dorsal strut of the tegumen that extends dorsally to the base of the uncus, a straight digitate process of the valva, a wider distal part of the valva, and a shorter apical cornutus of the aedeagus.

Description.— Head: Vertex and frontoclypeus brown; outer surface of labial palpus brown [many scales missing on specimens], inner surface pale brown; scape of antenna brown, flagellum pale brown; male 4th flagellomere not protuberant, 5th and 6th flagellomeres slightly excavated; proboscis brown.

Thorax: Tegula and mesonotum brown. Legs pale brown [many scales rubbed]. Forewing (Fig. 295): Length 5.6–5.8 mm (n = 2), brown. Undersurface brown. Hindwing: Pale brown.

Abdomen (Fig. 24): Male with 4 transverse, irregular rows of minute sex scales on intersegmental areas between terga 2–3 and terga 3–4.

Male Genitalia (Figs. 25–26): Uncus elongate, narrowly constricted above a widened base, gradually narrowed distally to an acuminate and setose apex; gnathos short, broadly rounded apically; tegumen slightly widened basally; dorsal strut with arms convergent, fusing medially from posteroventral margin to base of uncus; costa of valva broadly rounded from a shallow depression beyond an elongate, basal digitate process to apical furca; furca aristate; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate cucullus; cucullus membranous and setose, with a broadly rounded outer margin; aedeagus subapically constricted, forming a bulbous apex; vesica of aedeagus denticulate, bearing a short, conical cornutus; cornutus with one side shortened near 1/3 length, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 5 ): Glyphidocera orae is known from two collecting sites in northwestern Costa Rica, between the Cordillera de Guanacaste and the Pacific Coast.

Etymology: The species epithet orae is derived from the Latin “ora,” meaning coast.
