Glyphidocera zothecuale , new species

(Figs. 78–80, 313, Map 15 )

Diagnosis.— Glyphidocera zothecuale is most similar to G. sardae but differs by having a smaller gnathos, a shorter and less upturned costal furca of the valva, and a more angular outer margin of the valval cucullus.

Description.— Head: Vertex and frontoclypeus with grayish­brown scales tipped with pale brown; outer surface of labial palpus grayish brown intermixed with pale yellowishbrown scales to apical area of segments I–II; inner surface pale yellowish brown; scape of antenna pale yellowish brown intermixed with few grayish­brown scales, flagellum with alternating bands of pale yellowish­brown and brown scales; 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 yellowish brown.

Thorax: Tegula and mesonotum with grayish­brown scales tipped with pale brown. Legs grayish brown intermixed with yellowish­brown scales to near apical areas of all segments and tarsomeres. Forewing (Fig. 313): Length 8.0 mm (n = 1), pale yellowish brown intermixed with brown and grayish­brown scales tipped with pale brown; cell and surrounding areas paler than marginal areas; cell with 2 large brown spots, 1 near middle, 1 near distal end. Undersurface grayish brown intermixed with yellowish­brown scales along costa. Hindwing: Pale grayish brown.

Abdomen (Fig. 78): Male with 4 transverse, irregular rows of sex scales on intersegmental areas between terga 2–3 and terga 3–4. Sex scales between terga 2–3 are slightly larger and more numerous than sex scales between terga 3–4.

Male Genitalia (Figs. 79–80): Uncus elongate, slightly constricted broadly near 1/3, slightly rounded apically, tapering to an acuminate and setose apex; gnathos setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing near 2/3 length from a widened base along posteroventral margin to base of uncus; valva with costa broadly emarginate from a shallow depression beyond a basal digitate process to subapical part; subapical area slightly raised, with base of apical furca excavated; furca acuminate, slightly upturned; base of costa with a digitate process with a slightly widened base; sacculus twisted apically, constricting valva near 1/3 length, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus sparsely denticulate, bearing a large, crescent­shaped, apical cornutus; cornutus dilated basally, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 15 ): Glyphidocera zothecuale is known from one collecting site in northeastern Costa Rica, south of Tortuguero.

Etymology: The species epithet zothecuale is derived from the Latin “zothecula,” meaning small alcove.
