Diagnosis.— Glyphidocera rubetae can be distinguished from its congeners by a unique combination of characters that includes the dorsal strut of the tegumen with arms fused medially from the base of the posteroventral margin to midlength (forming a widened, pigmented, angular area from midlength to base of uncus), the digitate process of valva widened basally, the dorsal furca of valval costa long and extending beyond ventral furca, and the outer margin of the valval cucullus narrowly rounded.

Description.— Head: Scales on vertex and frontoclypeus brown tipped with pale brown; outer and inner surfaces of labial palpus brown intermixed with pale­brown scales to segment II; scape brown intermixed with pale­brown scales, flagellum with alternating bands of brown and pale­brown scales; male 4 th flagellomere 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 protuberance of 4 th flagellomere; proboscis brown.

Thorax: Tegula and mesonotum with brown scales tipped with pale brown. Legs brown intermixed with pale­brown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 359): Length 5.0–6.0 mm (n = 5), brown intermixed with pale­brown and pale brownish­yellow scales; cell and surrounding areas paler than marginal areas; cell with 2 brown spots, 1 spot near middle, 1 spot near distal end [rubbed specimens with spots faint or absent]. Undersurface brown. Hindwing: Pale brown.

Abdomen (Fig. 216): Male with 4 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 217–218): Uncus elongate, wide at base, broadly constricted near 1 / 3, broadly rounded apically, apex narrowly rounded and setose; gnathos setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms fused medially from base of posteroventral margin to midlength, extending dorsally, gradually widening to base of uncus; costa of valva broadly rounded from shallow depression beyond a slanted, basal, digitate process to a falcate dorsal furca; apex bifurcate, margin between furcae deeply dissected; sacculus twisted apically, constricting valva near midlength, widening distoventrally forming a broadly rounded and narrow cucullus; cucullus membranous and setose; vesica of aedeagus densely denticulate, bearing a large, crescent­shaped, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution (Map 40): Glyphidocera rubetae is known from two collecting sites from north­central Costa Rica north of the Cordillera Central and one site in the north­eastern part of the country, north of the Cordillera de Talamanca near the Panamian border.

Etymology: The species epithet rubetae is derived from the Latin “rubeta,” meaning toad.
