Glyphidocera tibiae , new species

(Figs. 168–170, 287, 343, Map 30) Diagnosis.— Glyphidocera tibiae is similar to G. novercae but differs from the latter by having an absence of sex scales between abdominal terga 2–3 in male, a wider dorsal furca of the valval costa, and a less protuberant ventral furca.

Description.— Head: Scales on vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus dark brown intermixed with pale­brown scales to apical margin of segment II, segment III pale brown intermixed with dark­brown scales; inner surface pale brown intermixed with few brown and dark­brown scales; scape of antenna pale brown intermixed with few dark­brown scales, flagellum with alternating bands of pale­brown and brown scales; male 4th flagellum 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 4th flagellomere; proboscis brown.

Thorax: Tegula and mesonotum brownish yellow intermixed with few dark­brown scales. Legs dark brown intermixed with pale brownish­yellow scales to apical margins of all segments and tarsomeres. Forewing (Fig. 343): Length 7.8–8.8 mm (n = 11), brownish yellow intermixed with few dark­brown scales; cell with Radius and Cubitus irregularly overlaid with dark­brown scales, and few dark­brown scales within [some rubbed specimens with dark­brown scales absent]. Undersurface brown intermixed with pale brownishyellow scales along costa. Hindwing: Pale brown.

Abdomen (Fig. 168): Male with with 4 transverse, irregular rows of sex scales on intersegmental membrane between terga 3–4.

Male Genitalia (Figs. 169–170): Uncus elongate, wide at base, broadly constricted near midlength, slightly widened laterally, apex setose, acuminate, and recurved; gnathos sparsely setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from posteroventral margin to base of uncus; costa of valva nearly straight from shallow depression slightly beyond a basal, digitate process to an inwardly curved dorsal furca; apex bifurcate, each furca widely divergent; dorsal furca large; ventral furca, a broadly rounded lobe; sacculus twisted apically, constricting valva slightly beyond midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing a narrowly elongate, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia (Fig. 287): Papillae anales elongate, wider basally than apically; apophysis posterioris and apophysis anterioris about equal in length; eighth sternum narrower than eighth tergum; eighth sternum with posterior margin broadly rounded, anterior margin broadly emarginate; eighth tergum with posterior margin nearly straight, anterior margin broadly emarginate; antrum enlarged posteriorly from a constricted anterior end, posterior margin nearly straight, posterolateral margin angular, anterior end with a pair of elongate, spinelike processes inside cavity formed from outer wall; ductus bursae short; corpus bursae slightly enlarged anteriorly, sparsely denticulate; ductus seminalis long, coils decreasing in size distally; ductus seminalis with a short, 5­coiled internal support; side opposite ductus bursae slightly swollen, with a moderately long, internal support.

Distribution ( Map 30): Glyphidocera tibiae is known from two collecting sites in Costa Rica; one in the north­west along the Cordillera de Guanacaste and one in the northcentral part of the country, north of the Cordillera Central.

Etymology: The species epithet tibiae is derived from the Latin “tibia,” meaning a reed pipe.
