Glyphidocera corniculae , new species

(Figs. 36–38, 299, Map 7 )

Diagnosis.— Glyphidocera corniculae is most similar to G. t e r r a e but differs by having a digitate process of valva that is apically dilated, an apical furca of valval costa that is shorter and more acutely upturned, and a larger apical cornutus of the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus brownish orange; labial palpus with outer margin brownish orange intermixed with few dark­brown scales, inner surface pale brownish orange intermixed with few brownish­orange scales; scape of antenna brownish orange, flagellomeres pale brownish orange; male 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6 [setiform scales on apex of protuberance of 4th flagellomere missing]; proboscis pale brownish orange.

Thorax: Tegula and mesonotum brownish orange. Legs pale brownish orange. Forewing (Fig. 299): Length 9.1 mm (n = 1), brownish orange with a brown spot near distal end of cell. Undersurface brownish orange. Hindwing: Brownish orange.

Abdomen (Fig. 36): Male with 4 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 37–38): Uncus elongate, wide at base, parallelsided to midlength, gradually narrowing to an acuminate and setose apex; gnathos sparsely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen absent; costa of valva gradually sloped to an abruptly upturned apical furca; furca with slightly serrate outer margin; base of costa with a digitate process with a knoblike apical process; sacculus twisted apically, constricting valva slightly before midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a broad and elongate apical cornutus; cornutus with a slightly shortened side, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Holotype, ɗ, “Est[ación] La Carsona, 1520 m, Res[erva] Biol[ógica] Monteverde, Prov[incia] Puntarenas, COSTA RICA, N. Obando, Ene. 1992, L­N­253250, 449700”, INBio: COSTA RICA: CRI000, 922216” [bar code label], “INBio, ɗ Genitalia Slide by D. Adamski, No. 830” [yellow label].

Distribution ( Map 7 ): Glyphidocera corniculae is known from one collecting site in the cloud forests of Monteverde in west­central Costa Rica along the southern part of the Cordillera de Tilarán.

Etymology: The species name corniculae is from the Latin “cornicula” meaning a little cow.
