Glyphidocera brumae , new species

(Figs. 93–95, 318, Map 18 )

Diagnosis.— Glyphidocera brumae is similar to G. dictionis but differs from the latter by having a larger uncus, a longer apical furca of the valval costa, and a straight outer margin of the cucullus of the valva.

Description.— Head: Vertex and frontoclypeus grayish yellow intermixed with few dark­brown scales laterally; outer surface of labial palpus dark brown intermixed with brownish­yellow scales to margin of segment II, inner margin pale brownish yellow intermixed with few dark­brown scales; scape of antenna brownish yellow intermixed with few dark­brown scales, flagellum with alternating pale brownish­yellow and pale­brown bands; male 4th 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 4th flagellomere; proboscis pale brownish yellow.

Thorax: Tegula and mesonotum pale brownish yellow. Legs grayish yellow intermixed with few dark­brown scales, grayish yellow along apical margins of all segments and tarsomeres or dark brown intermixed with few pale brownish­yellow scales to near apical margins of all segments and tarsomeres. Forewing (Fig. 318): Length 6.0–7.0 mm (n = 21), grayish yellow intermixed with few dark­brown scales; cell with 2 large, dark­brown spots, 1 near middle, 1 near distal end; one small spot on CuP posterior to midcell spot; marginal spots present or absent. Undersurface brown except, brownish yellow along costa. Hindwing: Pale gray.

Abdomen (Fig. 93): Male with 3 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3, and two elliptical­shaped clusters of sex scales on dorsolateral surface of intersegmental membrane between terga 3–4.

Male Genitalia (Figs. 94–95): Uncus elongate, wide at base, constricted broadly near midlength, widely rounded distally, tapering to rounded and setose apex; gnathos protuberant, distally upturned; tegumen slightly widened basally; dorsal strut with arms convergent medially, fused from posteroventral margin to base of uncus; costa of valva slightly broadly emarginate from a shallow depression beyond a slightly curved, digitate process to a slightly raised subapical part; apical furca acuminate, slightly upturned; sacculus twisted apically, constricting valva near midlength, widened distally forming an elongate and narrow cucullus; cucullus membranous and setose with a nearly truncate outer margin; vesica of aedeagus sparsely denticulate, bearing an apical cornutus; cornutus as wide as long, with one side shortened, exposing a wide and hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 18 ): Glyphidocera brumae is known from one collecting site in north­central Costa Rica north of the Cordillera Central.

Etymology: The species epithet brumae is derived from the Latin “bruma,” meaning winter solstice.
