Glyphidocera cauponae , new species

(Figs. 84–86, 315, Map 16 )

Diagnosis.— Glyphidocera cauponae can be distinguished from its congeners by the following unique combination of features: a broad dorsal strut of tegumen, an elongate digitate process of the valva, a short sacculus, an elongate and narrow cucullus of the valva, and an elongate furca of valval costa.

Description.— Head: Scales of vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus brown intermixed with pale­brown scales, segment II with pale­brown scales along apical margin; inner surface pale brown; scape of antenna pale brown intermixed with few brown scales, flagellum with alternating bands of brown and pale­brown scales; male 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; concavity open, setiform scales on apex of protuberance of 4th flagellomere absent; proboscis pale brown.

Thorax: Tegula and mesonotum pale brown or pale brown intermixed with few brown scales. Legs brown intermixed with pale­brown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 315): Length 8.0– 8.5 mm (n = 4), pale brown intermixed with few grayish­orange and brown scales; basal area with one short, brown streak on Radius or streak absent; cell with 4 brown spots, 2 near midcell, 2 near distal end. Undersurface brown. Hindwing: Brownish gray.

Abdomen (Fig. 84): Male with 4 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3 and terga 3–4. Sex scales from both areas are of about equal size.

Male Genitalia (Figs. 85–86): Uncus elongate, wide basally, slightly constricted near 1/3, wide at midlength narrowing apically to an acuminate apex; gnathos setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms abruptly convergent, fusing widely from posteroventral margin of tegumen to base of uncus; costa of valva slightly emarginate from beyond a shallow depression beyond an elongate, basal digitate process to apical furca; furca elongate, and slightly upturned; sacculus twisted apically, constricting valva slightly before midlength, slightly widening distoventrally, forming an elongate and narrow cucullus; cucullus membranous and setose; vesica of aedeagus densely spinulate, bearing a large apical cornutus; cornutus shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 16 ): Glyphidocera cauponae is known from four collecting sites in Costa Rica; two nearby sites in the northwest along the Cordillera de Guanacaste, one site along the southern side of the Cordillera Central in the west­central part of the country, and one site in north near the Caribbean coast.

Etymology: The species epithet cauponae is derived from the Latin word for tavern ­ caupona.
