Glyphidocera harenae , new species

(Figs. 219–221, 360, Map 40 )

Diagnosis.— Glyphidocera harenae is most similar to G. crepidae but differs from the latter by having an abdomen with more rows of sex scales between terga 2–3 in male, a complete dorsal strut of tegumen, a longer valva, costal furcae of valva near parallel, and vesica of aedeagus without spinelike cornuti.

Description.— Head: Scales on vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus brown intermixed with pale­brown scales to apical margin of segment II, inner margin pale brown intermixed with few brown scales; scape brown intermixed with few pale­brown scales, flagellum with alternating bands of brown and pale­brown 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 brown.

Thorax: Tegula and mesonotum brown. Legs brown intermixed with few pale­brown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 360): Length 5.0– 6.1 mm (n = 3), brown intermixed with few pale­brown scales; cell with 1 faint, brown spot near distal end. Undersurface brown. Hindwing: Brown.

Abdomen (Fig. 219): Male with 4 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 220–221): Uncus elongate, broadly constricted near 1/3, gradually widened apically, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut with arms convergent, fusing medially from posteroventral margin, extending dorsally to midlength, gradually widening to base of uncus; valva with costa gradually upturned broadly from a shallow depression beyond a slanted, basal, digitate process to a raised dorsal furca; apex bifurcate, furcae large, widely divergent, parallel; sacculus twisted apically constricting valva near midlength, widening distoventrally, forming a broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus densely denticulate, bearing a large, sickle­shaped, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Holotype, ɗ, “Est[ación] Sirena, P[arque] N[acional] Corcovado, 0–100 m, Prov[incia] Punt[arenas], COSTA RICA, G. Fonseca, Mar. 1991, L­S­ 270500, 508300”, “INBio: COSTA RICA: CRI000, 447830” [bar code label], “INBio, ɗ Genitalia Slide by D. Adamski, No. 799” [yellow label].

Paratypes (2 ɗ): Same label data as holotype except, “ Mar. 1992 ”, “CRI000, 780697”, “Slide No. 792”; “CRI000, 621786”, “Slide No. 801”, (1 in INBio, 1 in USNM).

Distribution ( Map 40 ): Glyphidocera harenae is known from one coastal collecting site in south­eastern Costa Rica, south of the Osa Peninsula.

Etymology: The species epithet harenae is derived from the Latin “harena,” meaning sand.
