Glyphidocera zamiae , new species

(Figs. 183–185, 348, Map 33 )

Diagnosis.— Glyphidocera zamiae is most similar to G. amitae but differs from the latter by having costal furcae of the valva more widely divergent from base, a wider cucullus, and larger cornuti within the vesica of the aedeagus.

Description.— Head: Vertex and frontoclypeus pale brown; [labial palpus missing]; scape and flagellum of antenna pale brown; 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 brown.

Thorax: Tegula and mesonotum pale brown. Legs pale yellowish brown. Forewing (Fig. 348): Length 8.9 mm (n = 1), pale brown intermixed with brownish­yellow scales, with no characteristic markings. Undersurface pale brown. Hindwing (Fig. 00): Pale brown.

Abdomen (Fig. 183): Male with two pairs of sex scale clusters on intersegmental membrane between terga 2–3 and terga 3–4; each cluster with 6 transverse, irregular rows of sex scales.

Male Genitalia (Figs. 184–185): Uncus elongate, wide at base, broadly constricted near 1/3, slightly 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 and extending from a narrow base to base of uncus; valva with costa nearly straight from shallow depression beyond a basal digitate process to dorsal furca; apex widely bifurcate, furcae divergent from a widely rounded inner margin; dorsal and ventral furcae about equal in length, dorsal furca with a rounded apex, ventral furca with a more narrowed apex; costal base bearing a straight, slanted, digitate process; sacculus twisted apically, constricting valva near 2/3 length, forming a short, broadly rounded, and protracted cucullus; cucullus membranous and setose; vesica with many stout and spinelike cornuti, and bearing an elongate, apical cornutus; cornutus shortened on one side near midlength, exposing a hollow, cavity.

Female Genitalia: Unknown.

Distribution ( Map 33 ): Glyphidocera zamiae is known from a single collecting site on the Osa Peninsula in south­eastern Costa Rica.

Etymology: The species epithet zamiae is derived from the Latin “zamia,” meaning harm.
