Glyphidocera cellae, new species

(Figs. 42–44, 296, Map 8)

Diagnosis.— Glyphidocera cellae can be distinguished from its congeners by a unique combination of features including a narrow gnathos with an acutely upturned apex, a costal furca with a broadly rounded apex, a shortened sacculus, a slightly constricted area beyond sacculus, an absence of an apical cornutus of the aedeagal vesica, and vesica of aedeagus with many spinelike cornuti.

Description.— Head: Vertex and frontoclypeus pale brownish yellow; outer surface of segments I–II brown intermixed with pale brownish­yellow scales to near apical margin, segment III brown intermixed with few pale brownish­yellow scales; inner surface pale brownish yellow intermixed with few brown scales; scape of antenna pale brownish yellow, flagellum with alternating bands of brown and pale brownish­yellow scales, male 4th flagellomere without dorsal protuberance, flagellomeres 5–6 slightly excavated; proboscis pale brownish yellow.

Thorax: Tegula brown intermixed with few brownish­yellow scales; mesonotum brownish yellow. Legs brownish yellow intermixed with few brown scales. Forewing (Fig. 296): Length 5.1 mm (n = 1), basal 2/3 pale brownish yellow intermixed with few brown scales, distal 1/3 brown intermixed with few pale brownish­yellow scales; cell with 2 brown spots, 1 near middle, 1 near distal end. Undersurface brown. Hindwing: Pale grayish brown basally, gradually darkening to apex.

Abdomen (Fig. 42): Male with 3 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 43–44): Uncus elongate, parallelsided from a wide base to an acuminate apex; gnathos setose, protuberant, wide basally, gradually narrowed distally, apex abruptly upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially and narrowly from posteroventral margin to base of uncus; costa slightly upturned from slightly beyond base to apical furca; furca wide, broadly rounded apically; basal digitate process of valva absent; sacculus moderately twisted, slightly constricting valva near midlength, slightly widening distoventrally, forming a broadly rounded cucullus; cucullus membranous and setose, with a narrowly rounded outer margin beneath apex of costa; vesica of aedeagus with many moderately long, spinelike cornuti.

Female Genitalia: Unknown.

Holotype, ɗ, “San Luis, Monteverde, Prov[incia] Punta[renas], COSTA RICA, 1000­ 1350 m, Jul. 1994, Z. Fuentes, L­N­ 250850, # 3074”, “INBio: COSTA RICA: CRI002, 025736” [bar code label], “INBio, Genitalia Slide by D. Adamski, Sex ɗ, No. 504” [yellow label].

Distribution (Map 8): Glyphidocera cellae is known from one collecting site in the cloud forests of Monteverde in west­central Costa Rica along the southern part of the Cordillera de Tilarán.

Etymology: The species epithet cellae is derived from the Latin “cella,” meaning room.
