Review of Glyphidocera Walsingham of Costa Rica (Lepidoptera: Gelechioidea: Glyphidoceridae) Author DAVID ADAMSKI text Zootaxa 2005 858 1 158 journal article 10.5281/zenodo.170793 94a0cedb-15bb-4bfd-955e-77200a536045 1175-5334 170793 511FBF55-10F2-4A00-B15B-CBD34EAB023E Glyphidocera arakawae , new species (Figs. 15–17, 292 , 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.

Distribution ( 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.
