Diagnosis.— Glyphidocera capsae is similar to G. audaciae but differs from the latter by having a wider gnathos, a wider distal part of valva, a larger costal furca of the valva, and a smaller apical cornutus of the aedeagal vesica.

Description.— Head: Scales of vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus brown intermixed with brownish­yellow scales, segment II with pale brownish­yellow scales along apical margin; inner surface pale brownish yellow intermixed with brown scales; scape of antenna brown intermixed with pale brownish­yellow scales, flagellum with alternating bands of brown and brownish­yellow scales; male 4 th 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 4 th flagellomere; proboscis brown with some scales tipped with pale brown.

Thorax: Tegula and mesonotum brown intermixed with brown scales tipped with pale brown. Legs brown intermixed with few pale­brown scales to near apical margins of all segments and tarsomeres. Forewing (Fig. 308): Length 6.9 –8.0 mm (n = 12), brown intermixed with pale brownish­yellow and pale­brown scales; cell and surrounding areas paler than marginal areas; cell with 2 large brown spots, 1 near middle, 1 near distal end. Undersurface brown except, costa pale yellowish brown. Hindwing: Pale brown.

Abdomen (Fig. 63): Male with 4 transverse, irregular rows of sex scales on intersegmental area between terga 2–3 and terga 3–4. Sex scales between terga 2–3 appear slightly larger than the sex scales between terga 3–4.

Male Genitalia (Figs. 64–65): Uncus elongate, slightly constricted from a wide base, nearly parallelsided apically, apex acuminate and setose; gnathos setose, protuberant, wide throughout length, upturned apically, tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a narrow base, fused narrowly above posteroventral margin of tegumen, gradually widening, forming a triangular­shaped pigmented area below base of uncus; costa of valva nearly straight from a shallow depression slightly beyond a slightly curved, basal digitate process to apical furca; furca acuminate, dorsally excavated, slightly upturned; sacculus twisted apically, constricting valva slightly before middle, widening distoventrally, forming an elongate, broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a small, crescent­shaped apical cornutus; cornutus abruptly dilated basally, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution (Map 11): Glyphidocera capsae is known from five collecting sites; four nearby coastal sites in south­central Costa Rica, and one collecting site in the north­central part of the country.

Etymology: The species epithet capsae is derived from the Latin “capsa,” meaning bookcase.
