Glyphidocera luxuriae , new species

(Figs. 234–236, 365, Map 43 )

Diagnosis.— Glyphidocera luxuriae , G. ambrosiae , and G. coturnicis share sex scales between abdominal terga 2–3 in the male, a wide gnathos, a dorsal strut of tegumen wide basally, a valval cucullus with a broadly rounded apicoventral margin, and costal furcae valva divergent. However, G. l u x u r i a e differs from the latter two by having larger abdominal sex scales between terga 2–3 in male, a shorter valval cucullus, costal furcae of valva more divergent, an absence of an apical cornutus within the vesica of the aedeagus, and a vesica with several spinelike cornuti.

Description.— Head: Vertex and frontoclypeus pale yellowish brown; outer margin of labial palpus brown intermixed with pale yellowish­brown scales to apical margin of segment II, inner surface pale yellowish brown intermixed with some brownish­orange scales; scape pale yellowish brown, flagellum brown; male 4th flagellomere 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 protuberance of 4th flagellomere; proboscis pale yellowish brown.

Thorax: Tegula and mesonotum brown. Legs with segments pale yellowish brown intermixed with brown scales to apical margin, tarsomeres brown intermixed with pale yellowish­brown scales to apical margin. Forewing (Fig. 365): Length 4.1 mm (n = 1), brown scales intermixed with pale­brown scales, outer marginal scales brown. Undersurface brown. Hindwing: Pale brown, slightly darkening to apex.

Abdomen (Fig. 234): Male with 3 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 235–236): Uncus elongate, wide at base, constricted near 1/3, broadly rounded apically, apex acuminate; gnathos sparsely setose, protuberant, wide throughout length, upturned apically, tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing near midlength, extending dorsally to base of uncus; costa of valva broadly rounded medially from a shallow depression beyond a slanted, basal, digitate process to an abruptly upturned dorsal furca; apex widely bifurcate, dorsal furca nearly erect, ventral furca extending slightly beyond outer margin of cucullus; sacculus twisted apically, constricting valva slightly beyond midlength, widening distoventrally, forming a broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with many spinelike cornuti of varying lengths.

Female Genitalia: Unknown.

Holotype, ɗ, “Cerro Tortuguero, 0–120 m, P[arque] N[acional] Tortuguero, Prov[incia] Limón, COSTA RICA, Ene. 1993, R. Delgado, L­N­285000, 588000”, “INBio: COSTA RICA: CRI001, 352791” [bar code label], “INBio, ɗ Genitalia Slide by D. Adamski, No. 605” [yellow label].

Distribution ( Map 43 ): Glyphidocera luxuriae is know from one collecting site in northern Costa Rica near the north­western coast of Limón.

Etymology: The species epithet luxuriae is derived from the Latin word “luxuria”or luxury.
