Glyphidocera arae , new species

(Figs. 81–83, 314, Map 15 )

Diagnosis.— Glyphidocera arae is similar to G. p l e b i s but differs from the latter by having smaller sex scales between abdominal terga 2–3 in male, a tegumen with a more developed dorsal strut, broader cucullus of valva, and a shorter apical furca of the valval costa.

Description.— Head: Scales of vertex dark brown tipped with pale yellow, frontoclypeus pale yellow intermixed with dark­brown marginal scales; outer surface of labial palpus dark brown intermixed with few pale­yellow scales, segment II with pale­yellow scales along apical margin; inner surface pale yellow intermixed with few dark­brown scales; scape of antenna dark brown intermixed with few pale­yellow scales, flagellum with alternating bands of brown and pale­yellow scales; male 4th flagellomere not protuberant, 5th and 6th flagellomeres slightly excavated; proboscis pale yellow.

Thorax: Tegula dark brown intermixed with pale­yellow scales apically, or dark brown intermixed with grayish­orange scales; mesonotum pale yellow intermixed with few darkbrown scales or grayish orange intermixed with few dark­brown scales. Legs brown intermixed with pale­yellow scales on apical margins of all segments and tarsomeres. Forewing (Fig. 314): Length 7.0– 7.2 mm (n = 3), grayish orange and pale­yellow scales intermixed with dark­brown and brown scales; base with 1 or 2 dark­brown short streaks along Radius; cell with 4 dark­brown spots, 2 near middle, 2 spots near distal end; veins arising from cell sparsely overlaid with dark­brown scales to marginal spots. Undersurface brown. Hindwing: Brownish gray.

Abdomen (Fig. 81): Male with 3 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 82–83): Uncus elongate, wide basally, slightly constricted near 1/3 length, widest near midlength, gradually narrowed to a rounded apex; gnathos setose, protuberant, wide throughout length, upturned apically; tegumen narrow, parallelsided throughout length; dorsal strut of tegumen with arms convergent from a wide base, fusing near midlength between posteroventral margin and base of uncus; costa of valva broadly emarginate medially from a shallow depression beyond a slanted, basal digitate process to a raised subapical part; apical furca acuminate, slightly upturned; sacculus twisted apically, constricting valva slightly before midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose, with outer margin short, slanted to a narrowly rounded apicoventral margin; vesica of aedeagus denticulate, bearing an elongate, apical cornutus; cornutus shortened near midlength on one side, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Holotype, ɗ, “San Luis, Monteverde, Prov[incia] Punta[renas], COSTA RICA, 1000– 1350 m, Feb. 1995, Z. Fuentes, L­N­ 250850, 449250, # 4393”, “INBio” COSTA RICA: CRI002, 165554” [bar code label], “INBio, Genitalia Slide by D. Adamski, Sex ɗ, No. 497” [yellow label].

Paratypes (2 ɗ): Same label data as holotype except, “Buen Amigo, Set. 1994, # 3224”, “CRI 0 0 2, 022118 ”, “Slide No. 501”, “CRI002, 022097 ”, “Slide No. 502”, (1 in INBio, 1 in USNM).

Distribution ( Map 15 ): Glyphidocera arae is known from one collecting site in westcentral Costa Rica, along the southern slope of the Cordillera de Tilarán.

Etymology: The species epithet arae is derived from the Latin “ara,” meaning altar.
