Glyphidocera barbae , new species

(Figs. 192–194, 351, Map 35 )

Diagnosis.— Glyphidocera barbae is most similar to G. p a l i but differs from the latter by having a dorsal strut of tegumen widened basally (and atrophied dorsally), and more widely separate costal furcae of the valva.

Description.— Head: Vertex and frontoclypeus brown; outer and inner surfaces of labial palpus brown intermixed with pale­brown scales to apical margin of segment II, segment III pale brown intermixed with few brown scales; scape of antenna brown, flagellum with alternating bands of pale­brown and brown 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 brown.

Thorax: Tegula and mesonotum brown. Legs brown intermixed with pale­brown scales to apical margins of all segments and tarsomeres. Forewing (Fig. 351): Length 6.0– 6.2 mm (n = 2), brown intermixed with pale­brown scales; cell with 2 small, brown spots, one spot near middle, one spot near distal end. Undersurface brown. Hindwing: Brown with pale­brown scales between CuP and anal margin.

Abdomen (Fig. 192): Male with a two pairs of elliptical­shaped 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 between terga 2–3 are twice as large as the sex scales between terga 3–4.

Male Genitalia (Figs. 193–194): Uncus elongate, wide at base, broadly constricted near ½, broadly rounded subapically, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing dorsally and atrophied beneath base of uncus; costa of valva nearly straight from a shallow depression beyond a basal digitate process to an upturned dorsal furca; apex widely bifurcate, margin between furcae narrowly rounded; furcae divergent, dorsal furca slightly longer than ventral furca; sacculus twisted apically constricting valva near midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus with several spinelike cornuti, and bearing an elongate, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 35 ): Glyphidocera barbae is known from two collecting sites in north­central Costa Rica; one site along the Cordillera Central, and a second site near the Caribbean Coast.

Etymology: The species epithet barbae is derived from the Latin word for beard ­ barba.
