(Figs. 15–17, 292, Map 3View MAP 3)

Diagnosis.— Relationships between Glyphidocera arakawae  and other species of Glyphidocera  are difficult to determine because of the unique features it possesses that include a narrow uncus and gnathos, a straight and wide digitate process of the valva, an angular apicoventral margin of valva, a straight lower margin of the distal valva, a short row of sex scales on dorsolateral membrane between abdominal terga 2–3 in male, and a dense cluster of piliform sex scales on dorsolateral membrane between abdominal terga 3–4 in the male.

Description.— Head: Vertex and frontoclypeus pale yellow; outer surface of labial palpus pale yellow intermixed with dark­brown scales or segment I and segment II dark brown and segment III dark brown intermixed with few pale­yellow scales, inner surface pale yellow; scape of antenna dark brown intermixed with pale­yellow scales or pale yellow intermixed with few dark­brown scales, flagellomeres with alternating bands of paleyellow and brown scales; male 4 th flagellomere dorsally protuberant and curved, forming a narrow and deep concavity opposite slightly excavated flagellomeres 5–6; distal opening of concavity nearly closed by setiform scales on apex of 4 th flagellomere; proboscis pale yellow.

Thorax: Tegula brown basally, pale yellow apically; mesonotum pale yellow. Foreleg dark brown with pale­yellow scales near apical margins of all segments and tarsomeres, pterothoracic legs pale yellow. Forewing (Fig. 292): Length 5.1 –7.0 mm (n = 6), pale yellow intermixed with dark­brown scales; costal margin mostly dark brown intermixed with pale­yellow scales, 1 large, dark­brown spot near middle of R 1; base of Radius with 2 short, dark­brown streaks; cell with 2 large dark­brown spots, 1 near middle, 1 near distal end; termen and outer margin pale yellow or mostly dark brown, with 2–3 marginal spots from subapical area. Undersurface pale brownish gray. Hindwing: Pale brownish gray.

Abdomen (Fig. 15): Male with two short rows, of 6–8 sex scales each, on dorsolateral part of intersegmental area between terga 2–3, and two dense clusters of piliform scales on dorsolateral part of intersegmental area between terga 3–4.

Male Genitalia (Figs. 16–17): Uncus elongate, wide at base, broadly constricted near 2 / 3 length, forming a slightly widened, setose apex; gnathos setose, protuberant, narrow throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing slightly beneath base of uncus; valva short, narrow, parallelsided from distal sacculus to apcal furca; furca attenuate; base of costa with a decumbent digitate process; sacculus weakly twisted apically, slightly constricting valva near midlength; cucullus membranous and sparsely setose; vesica of aedeagus, denticulate, bearing a slightly narrowed and elongate, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 3View MAP 3): Glyphidocera arakawae  is known from four collecting sitesin Costa Rica; three approximate sites in the northwest along the Cordillera de Guanacaste, and one collecting site along the Cordillera de Tilarán in the west­central part of the country.

Etymology: Glyphidocera arakawae  is named in honor of Kuniko Arakawa, who provided the illustrations of the genitalia for this revision.
