Glyphidocera pilae , new species

(Figs. 162–164, 341, Map 29 ) Diagnosis.— Glyphidocera pilae is most similar to G. glaebae but differs from the latter by having a shorter gnathos, more widely separate costal furcae of valva, and dorsal furca of valval costa oriented dorsally.

Description.— Head: Vertex and frontoclypeus pale yellow; labial palpus with outer and inner surfaces pale yellow; scape of antenna pale yellow, flagellum with alternating bands of pale­yellow and pale­brown scales; male with 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 pale yellow.

Thorax: Tegula and mesonotum pale yellow. Legs pale yellow intermixed with few pale­brown scales. Forewing (Fig. 341): Length 7.0 mm (n = 1), pale yellow intermixed with brown scales; cell with 2 recurrent spots, 1 near base, 1 on distal end; several small brown spots on Cubitus and one brown spot on CuP; marginal scales brown. Undersurface pale brown. Hindwing: Pale brown, except pale­yellow scales in anal area.

Abdomen (Fig. 162): Male with few sex scales along medial area of intersegmental membrane between terga 2–3, and 4 transverse, irregular rows of sex scales on intersegmental areas between terga 3–4.

Male Genitalia (Figs. 163–164): Uncus elongate, wide at base, slightly narrowing apically, abruptly curved near 2/3, apex narrowly rounded setose; gnathos short, apically truncate; tegumen near parallelsided throughout length; dorsal strut of tegumen with arms convergent, fusing about 1/4 length between posteroventral margin and base of uncus, dorsally atrophied; costa of valva broadly emarginate medially from a shallow, basal digitate process to slightly upturned dorsal furca; apex widely bifurcate, dorsal furca triangular and pointed, about twice as large as a slightly downcurved ventral furca; base of costa bearing a straight, digitate process; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate and broadly rounded, narrow cucullus; cucullus membranous and setose; vesica of aedeagus with many stout, conical cornuti, and bearing a large conical, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 29 ): Glyphidocera pilae is known from a single collecting site in north­central Costa Rica.

Etymology: The species epithet pilae is derived from the Latin “pila,” meaning ball.
