Glyphidocera virgulae , new species

(Figs. 138–140, 283, 333, Map 25 ) Diagnosis.— Glyphidocera virgulae is most similar to G. personae but can be distinguished by its wider base of the dorsal strut of the tegumen, longer digitate process of the valva, and more protracted outer margin of the valval cucullus.

Description.— Head: Vertex dark brown; frontoclypeus dark brown intermixed with few yellow scales; outer surface of labial palpus with segments I–II dark brown intermixed with yellow scales, segment III dark brown; inner surface with segments I–II yellow, segment III dark brown; scape of antenna yellow, basal 8–10 flagellomeres yellow, remaining flagellomeres dark brown; male 4th flagellomere distally dilated, protuberant and curved, forming a deep concavity opposite deeply excavated flagellomeres 5–6; proboscis yellow.

Thorax: Tegula and mesonotum dark brown. Legs dark brown intermixed with yellowish­brown scales to near apical margins of all segments and tarsomeres. Forewing (Fig. 333): Length 4.0– 5.7 mm (n = 31), dark brown. Undersurface dark brown. Hindwing: Dark brown.

Abdomen (Fig. 138): Male with 5 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3 and one transverse row of sex scales on intersegmental membrane between terga 3–4. Sex scales between terga 2–3 at least twice as large as the sex scales between terga 3–4.

Male Genitalia (Figs. 139–140): Uncus elongate, wide at base, broadly constricted near 1/3, broadly rounded apically, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from a wide base, extending dorsally and widely to base of uncus; costa of valva slightly upturned from shallow depression beyond basal, digitate process to dorsal furca; apex bifurcate, each furca small, widely separate, and about equal in size; sacculus twisted apically, constricting valva slightly beyond midlength, widening distoventrally, forming a broadly rounded and distally protracted cucullus; cucullus membranous and setose; vesica of aedeagus with several small spinelike cornuti, and bearing a large, conical apical cornutus; cornutus with one side shortened, exposing a hollow, basal cavity.

Female Genitalia (Fig. 283): Papillae anales elongate, slightly wider basally than apically; apophysis posterioris and apophysis anterioris about equal in length; eighth sternum about equal in width as eighth tergum; eighth tergum with posterior and anterior margins nearly straight, eighth sternum with posterior margin slightly emarginate medially, anterior margin broadly emarginate; antrum posteriorly enlarged from a constricted anterior part; posterior margin nearly straight, posterolateral margins angular; anterior end with a pair of elongate, spinelike processes within cavity formed from outer wall; ductus bursae short; corpus bursae denticulate within anterior half and slightly wider anteriorly; ductus seminalis large, coiled from base to distal end, coils gradually decreasing in size distally; ductus seminalis with a long, 8­coiled, internal support; side opposite ductus seminalis slightly bulbus with an elongate, platelike, support at base.

Distribution ( Map 25 ): Glyphidocera virgulae is known from two collecting sites in north­western Costa Rica along the Cordillera de Guanacaste and one site in the north­central part of the country, north of the Cordillera Central.

Etymology: The species epithet virgulae is derived from the Latin word ”virgula” which means wand.
