Glyphidocera crepidae , new species

(Figs. 222–224, 361, Map 41 )

Diagnosis.— Glyphidocera crepidae is most similar to G. harenae but differs from the latter by having an abdomen with fewer rows of sex scales between terga 2–3 in male, an incomplete dorsal strut of tegumen, a shorter valva, costal furcae of valva not parallel [ventral furca apically upturned abruptly], and vesica of aedeagus with many spinelike cornuti.

Description.— Head: Vertex and frontoclypeus brown intermixed with few palebrown scales; labial palpus with outer surface of segments brown intermixed with few pale brownish­yellow scales to apical margin on segments I–II, segment III brown intermixed with few pale brownish­yellow scales; inner surface as above except with more pale brownish­yellow scales on segments I–II; scape of antenna brown intermixed with few pale brownish­yellow scales, flagellum with alternating bands of brown and pale brown scales; 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 brownish yellow.

Thorax: Tegula and mesonotum brown. Legs with segments brown intermixed with pale brownish­yellow scales, tarsomeres brown with pale brownish­yellow scales to apical margin. Forewing (Fig. 361): Length 5.1 mm (n = 1), brown intermixed with pale brownish­yellow scales; cell with 3 brown spots, 1 spot near middle, 2 spots slightly coalescent, at distal end parallel with crossvein; marginal spots brown. Undersurface brown. Hindwing: Brown.

Abdomen (Fig. 222): Male with 2 transverse rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 223–224): Uncus elongate, wide at base, slightly constricted above, parallelsided apically, apex narrowly rounded and setose; gnathos densely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from posteroventral margin to 1/3 length, dorsally atrophied; valva with costa slightly sloped dorsally from a shallow depression beyond a slanted, basal, digitate process to dorsal furca; apex widely bifurcate, inner margin U­shaped; dorsal furca falcate, ventral furca abruptly angled apically, slightly broader than dorsal furca; sacculus twisted apically, constricting valva at midlength, forming a ventrally protracted cucullus; cucullus membranous and setose; vesica of aedeagus with many moderately elongate, spinelike cornuti, and bearing a large, crescent­shaped, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Holotype, ɗ, “ COSTA RICA, Heredia, Est[ación] Biol[ógica] La Selva, 50–150 m, 10°26'N, 84°01'W, June 1994, INBio­OET”, “ 28 Junio 1994, Bosque secundario, L/06/ 107”, “INBio: COSTA RICA: CRI001, 243975” [bar code label], “INBio, ɗ Genitalia Slide by D. Adamski, No. 904” [yellow label].

Distribution ( Map 41 ): Glyphidocera crepidae is known from one collecting site in east­central Heredia in northern Costa Rica.

Etymology: The species epithet crepidae is derived from the Latin “crepida,” meaning slipper.
