Glyphidocera amitae , new species

(Figs. 180–182, 347, Map 33 )

Diagnosis.— Glyphidocera amitae is most similar to G. z a m i a e but differs from the latter by having costal furcae of the valva more narrowly divergent from base, a narrower cucullus, and small cornuti within the vesica of the aedeagus.

Description.— Head: Vertex and frontoclypeus grayish brown; labial palpus with outer surface grayish brown intermixed with pale brownish­yellow scales, inner surface pale brownish yellow intermixed with few grayish­brown scales; scape of antenna grayish brown intermixed with few brown scales, flagellum with alternating bands of grayishbrown and pale brownish­yellow scales; male 4th flagellomere dorsally protuberant and curved, forming a shallow concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a few setiform scales on apex of protuberance of 4th flagellomere; proboscis pale grayish brown.

Thorax: Tegula and mesonotum grayish brown. Legs pale brownish yellow. Forewing (Fig. 347): Length 8.8 mm (n = 1), pale brown intermixed with few pale brownish­yellow scales; cell with 2 faint grayish brown spots, 1 spot near middle, 1 spot on distal end near crossvein. Undersurface pale grayish brown. Hindwing: Pale brown.

Abdomen (Fig. 180): Male with pair of sex scale clusters, each with 6–7 transverse, irregular rows of scales, on intersegmental areas between terga 2–3 and terga 3–4.

Male Genitalia (Figs. 181–182): Uncus elongate, wide at base, broadly constricted about 1/3, slightly rounded distally, apex narrowly rounded; gnathos sparsely setose, protuberant, narrow throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from posteroventral margin to base of uncus; costa of valva nearly straight from shallow depression slightly beyond a basal, digitate process to an upturned dorsal furca; apex widely bifurcate, inner margin V­shaped; dorsal furca wide, with a rounded apex, ventral furca acuminate, slightly longer than dorsal furca; base of costa bearing a curved and slanted, digitate process; sacculus twisted apically, constricting valva slightly beyond midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica with denticulate, bearing a elongate, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Holotype, ɗ, “Buen Amigo, San Luis Monteverde, Prov[incia] Punta[renas], COSTA RICA, 1000–1350 m, Set. 1994, Z. Fuentes, L­N­ 250850, 449250, # 3224”, “INBio: COSTA RICA: CRI002, 022083 ” [bar code label], “INBio, Genitalia Slide by D. Adamski, Sex ɗ, No. 517” [yellow label].

Distribution ( Map 33 ): Glyphidocera amitae 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 amitae is derived from the Latin “amita,” meaning aunt.
