Glyphidocera caveae , new species

(Figs. 174–176, 345, Map 32)

Diagnosis.— Glyphidocera caveae is most similar to G. s t a e r a e but differs from the latter by having a wider digitate process of valva, more widely separate costal furcae of the valva, a wider valval cucullus, and a stout apical curnutus of the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus pale yellowish brown; labial palpus with outer surface of segments I–II brown intermixed with pale yellowish­brown scales to near apical margin, segment III brown intermixed with pale yellowish­brown scales; inner surface pale yellowish brown intermixed with few brown scales; scape of antenna pale yellowish brown intermixed with few brown and dark­brown scales, flagellum with alternating bands of pale yellowish­brown and pale­brown scales; 4th flagellum 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 4th flagellomere; proboscis pale yellowish brown.

Thorax: Tegula and mesonotum pale yellowish brown. Legs pale brown intermixed with pale yellowish­brown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 345): Length 8.1 mm (n = 1), pale yellowish brown intermixed with reddish­brown and dark­brown scales; several dark­brown spots within cell; 1 spot near base, 2 spots in recurrent line near middle, and 2 spots in diagonal line on distal end; marginal spots present or absent. Undersurface pale brown. Hindwing: Pale brown, with pale yellowish­brown scales on anal area.

Abdomen (Fig. 174): Male with two short, irregular rows of sex scales on medial intersegmental area between terga 2–3, and two transverse rows of sex scales between terga 3–4.

Male Genitalia (Figs. 175–176): Uncus elongate, wide at base, constricted near middle, apical 1/2 triangular­shaped, apex setose, acuminate, and slightly recurved; gnathos sparsely setose, protuberant, wide throughout length, upturned apically; tegumen slightly narrowed basally; dorsal strut of tegumen with arms convergent and fused, atrophied dorsally; valva with costa gradually upturned from a shallow depression beyond a slightly curved, basal, digitate process to dorsal furca; apex widely bifurcate, dorsal furca narrower than ventral furca; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate and angular cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a moderately long, conical, apical cornutus; cornutus with a shortened side near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution (Map 32): Glyphidocera caveae is known from one collecting site in north­western Costa Rica along the Cordillera de Guanacaste.

Etymology: The specific epithet caveae is derived from “cavea,” the Latin word for cavity.
