Glyphidocera terrae , new species

(Figs. 39–41, 280, 297, Map 7 ) Diagnosis.— Glyphidocera terrae is most similar to G. c o r n i c u l a e but differs from the latter by having a digitate process of valva that is not apically dilated, an apical furca of the valval costa that is longer and less acutely upturned, and a smaller apical cornutus of the aedeagal vesica.

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

Thorax: Tegula and mesonotum brown. Legs brown intermixed with pale­brown scales to near apical margins of all segments and tarsomeres. Forewing (Fig. 297): Length 7.1–8.0 mm (n = 13), brown intermixed with few pale­brown scales; cell and surrounding areas paler than marginal areas; cell with 2 large brown spots, 1 near middle, 1 near distal end; Undersurface brown. Hindwing: Brownish gray.

Abdomen (Fig. 39): Male with 2 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 40–41): Uncus elongate, broadly constricted near basal 1/4, nearly parallelsided apically, apex slightly rounded and setose; gnathos protuberant, wide basally, abruptly narrowed distal half and apically upturned, apex narrowly rounded; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially from posteroventral margin to base of uncus; costa of valva gradually upturned from a shallow depression beyond basal digitate process to apical furca; furca angular and elongate, extending beyond base of uncus; sacculus twisted apically, constricting valva slightly before midlength, widening distoventrally, forming an elongate cucullus; cucullus membranous and setose, with a nearly straight and elongate outer margin; vesica of aedeagus denticulate, with an elongate, conical, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia (Fig. 280): Papillae anales elongate, slightly wider basally than apically; apophysis posterioris and apophysis anterioris about equal in length; eighth sternum narrower than eighth tergum; posterior margin of eighth sternum broadly rounded, anterior margin emarginate; posterior margin of eighth tergum broadly emarginate, anterior margin broadly rounded; antrum enlarged posteriorly from a narrow anterior part, posterior margin broadly rounded, posterolateral margin angular; constricted anterior part with a pair of short, spinelike processes inside cavity formed from outer wall; ductus bursae short; corpus bursae slightly expanded posteriorly, denticulate on anterior 2/3; inception of ductus seminalis enlarged; ductus seminalis coiled throughout length, decreasing in diameter from a widened base to apex; base of ductus seminalis with a small, single­coiled, internal support; a slightly enlarged bulla opposite side of ductus seminalis; bulla with a twisted, platelike, internal support.

Distribution ( Map 7 ): Glyphidocera terrae is known from three collecting sites in north­western Costa Rica along the Cordillera de Guanacaste, and one collecting site north of San José, along the Cordillera Central.

Etymology: The species epithet is derived from the Latin word for earth ­ terra.
