Glyphidocera arenae , new species

(Figs. 246–248, 369, Map 45 View MAP 45 )

Diagnosis.— Glyphidocera arenae , G. fabulae , G. sapphiri share abdominal sex scales between terga 2–3 in male, an elongate valval cucullus, and an elongate and narrow apical cornutus within the vesica of the aedeagus. G. arenae can be distinguished from the latter two species by having a dorsal strut of the tegumen with the arms narrowly convergent to midlength between the posteroventral margin and the base of the uncus (fusing dorsally near base of uncus) and the costal furcae of the valva wider apart.

Description.— Head: Scales on vertex and frontoclypeus grayish brown tipped with pale grayish brown; outer surface of labial palpus brown intermixed with pale­brown scales to apical margin of segment II, inner surface pale brown intermixed with few brown scales; scape of antenna pale brown intermixed with few brown scales, flagellum with alternating bands of pale­brown and brown scales; male 4th flagellomere dorsally protuberant and curved, forming a shallow concavity opposite slightly excavated flagellomeres 5–6 [setiform scales associated with 4th flagellomere are missing]; proboscis pale brown.

Thorax: Tegula and mesonotum with grayish­brown scales tipped with pale grayish brown. Legs brown intermixed with pale­brown scales to distal margins of all segments and tarsomeres. Forewing (Fig. 369): Length 6.3–6.5 mm (n = 3), pale brown intermixed with few brown scales; basal area with one small brown spot near middle; cell with 2 brown spots, 1 large oblique spot near middle, 1 small spot near distal end; midcell spot coalescent with a small, brown spot on CuP. Undersurface brown intermixed with palebrown scales along costal margin. Hindwing: Brownish gray.

Abdomen (Fig. 246): Male with 3 transverse rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 247–248): Uncus elongate, wide at base, broadly constricted near 1/3, nearly parallelsided apically, apex acuminate and setose; gnathos setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a wide base, fusing slightly beyond midlength, extending dorsally to base of uncus; costa of valva slightly emarginate broadly from shallow depression beyond basal digitate process to a slightly upturned dorsal furca; apex widely bifurcate, slightly divergent; dorsal furca about 3 times larger than ventral furca; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing an elongate, conical, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Paratypes (2 ɗ): Same label data as holotype except, “ Nov. 1990 ”, “CRI000, 180482 ”, “Slide No. 537”; “R. Zuniga, Ene. 1991, L­S­370900, 448800”, “Slide No. 541”, (1 in INBio, 1 in USNM).

Distribution ( Map 45 View MAP 45 ): Glyphidocera arenae is known from two nearby coastal collecting sites in south­central Costa Rica.

Etymology: The species epithet arenae is derived from the Latin “arena.”
