Glyphidocera laricae   , new species

(Figs. 189–191, 350, Map 34 View MAP 34 )

Diagnosis.— Glyphidocera laricae   is most similar to G. cenulae   but differs from the latter by having a smaller gnathos, a smaller digitate process of the valva, equal costal furcae of the valva, a narrower valval cucullus, and a larger apical cornutus of the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus pale brown; labial palpus with outer surface brown intermixed with few pale brownish­yellow scales, inner surface pale brownish yellow; scape pale brownish yellow, flagellum with alternating bands of pale­brown and brown scales; male 4 th 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 4 th flagellomere; proboscis pale brownish yellow.

Thorax: Tegula and mesonotum pale brown. Legs with segments pale brownish yellow, tarsomeres pale brown intermixed with few brown scales and pale brownish­yellow scales along apical margin. Forewing (Fig. 350): Length 6.8 mm (n = 1), brownish yellow intermixed with few pale­brown and brown scales, with no characteristic markings. Undersurface brown. Hindwing: Pale brown, scales on anal area mostly pale brownish yellow.

Abdomen (Fig. 189): Male with two pairs of sex scale clusters on intersegmental membrane between terga 2–3 and terga 3–4; each cluster with 3 transverse, irregular rows of sex scales. [Sex scales on paired clusters between terga 2–3 have been rubbed off during dissection]

Male Genitalia (Figs. 190–191): Uncus elongate, wide at base, broadly constricted near 1 / 3, widely rounded apically, apex acuminate and setose; gnathos setose, narrow, protuberant, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a widened base, extending to base of uncus; costa of valva nearly straight from a shallow depression beyond a basal digitate process to a slightly upturned dorsal furca; apex widely bifurcate, each furca about equal in size; base of costa bearing a slanted, digitate process, abruptly curved apically; sacculus twisted apically, constricting valva near midlength, forming elongate, slightly rounded, cucullus; cucullus membranous and setose; vesica of aedeagus with denticulate, bearing a small, conical, apical cornutus.

Female Genitalia: Unknown.

Distribution ( Map 34 View MAP 34 ): Glyphidocera laricae   is known from a single collecting site on the Osa Peninsula in south­eastern Costa Rica.

Etymology: The species epithet laricae   is derived from the Latin “larica,” meaning breast­plate.
