Glyphidocera lanae , new species

(Figs. 102–104, 321, Map 19 )

Diagnosis.— Glyphidocera lanae is similar to G. n o t a e but differs from the latter by having abdominal sex scales between terga 2–3 and terga 3–4 in male, and a narrower cucullus.

Description.— Head: Scales of vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus brown intermixed with pale­brown scales, segment II with pale­brown scales along apical margin; inner surface pale brown intermixed with few brown scales; scape of antenna 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 intermixed with few brown scales tipped with pale brown. Legs brown intermixed with brown scales tipped with pale brown, and palebrown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 321): Length 6.0– 6.9 mm (n = 2), pale brown intermixed with brown scales tipped with pale brown and few brown scales; area between crossvein of cell and outer margin darkly patterned; cell with 2 large brown spots, 1 near middle, 1 near distal end; one short, brown streak along CuP, posterior and slightly basal to midcell spot. Undersurface brown except, pale brown along costal margin. Hindwing: Grayish brown.

Abdomen (Fig. 102): Male with 3 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3 and between terga 3–4.

Male Genitalia (Figs. 103–104): Uncus elongate, base wide, constricted near 2/3, widening apically, apex setose and acuminate; gnathos sparsely setose, protuberant; narrow throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a wide base, fusing narrowly at midlength, gradually widening to base of uncus; costa of valva nearly straight from a shallow depression beyond a slanted, digitate process to a downturned apical furca; furca falcate, nearly as long as width of distal valva; sacculus twisted apically, constricting valva near middle, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus sparsely denticulate, bearing moderately large, crescent­shaped cornutus; cornutus with one side shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Holotype, ɗ, “Est[ación] Carrillo, 700 m, P[arque] N[acional] Braulio Carrillo, Prov[incia] S[an] José, COSTA RICA, I curso Microlepidoptera, Jul. 1990, L­N­236700, 541800”, “INBio: COSTA RICA: CRI000, 067341” [bar code label], “INBio, ɗ Genitalia Slide by D. Adamski, No. 842” [yellow label]. Holotype is missing labial palpi and antennae.

Paratype 1 ɗ, “Same label data as holotype except, “CRI000, 067325”, “Slide No. 834.”

Distribution ( Map 19 ): Glyphidocera lanae is known from one collecting site in northcentral Costa Rica along the Cordillera Central.

Etymology: The species epithet lanae is derived from the Latin “lana,” meaning wool.
