Glyphidocera lawrenceae , new species

(Figs. 99–99a, 100–101, 320, Map 19 ) Diagnosis.— Relationships between Glyphidocera lawrenceae and its congeners are difficult to determine because of the unique features possessed by the former that include a narrow, transverse, sclerotized band between terga 2–3 and terga 3–4, posterior margin of fourth tergum emarginate medially, a pair of piliform sex­scale bundles on posterolateral margins of segment eight in male, small gnathos, a long digitate process of the valva, valva acutely constricted near 3/4 length, costa of valva curved dorsolaterally, and vesica of aedeagus with an elongate and narrow apical cornutus.

Description.— Head: Vertex and frontoclypeus pale yellowish orange; outer surface of labial palpus brown intermixed with pale yellowish­orange scales to apical margin of segments I–II, inner surface pale yellowish orange; scape and flagellum of antenna pale yellowish orange; 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 yellowish orange.

Thorax: Tegula and mesonotum yellowish orange. Legs pale yellowish orange intermixed with few brown scales. Forewing (Fig. 320): Length 5.9 mm (n = 1), yellowish orange intermixed with pale­yellow scales and few brown scales along costa and area beyond cell; cell with 2 brown spots, 1 near middle, 1 near distal end. Undersurface pale brown intermixed with pale yellowish­orange scales along submarginal and marginal areas. Hindwing: Pale brown.

Abdomen (Fig. 99–99a): Male with a narrow, transverse, sclerotized band between terga 2–3 and terga 3–4; posterior margin of fourth tergum emarginate medially; eighth segment with two bundles of elongate piliform sex scales, each on posterolateral margin.

Male Genitalia (Figs. 100–101): Uncus elongate, broadly constricted above a wide base, slightly widened apically, apex setose and acuminate; gnathos sparsely setose, protuberant, narrow throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially beneath base of uncus; costa of valva slightly downcurved from about 2/3; costa with a basally wide and acuminate apical furca; base of costa with a straight, elongate, digitate process; sacculus twisted apically, constricting valva near 3/4, widening distoventrally, forming an angular cucullus; cucullus membranous and setose; outer margin S­shaped; vesica of aedeagus denticulate [some large], bearing a narrow, elongate, apical cornutus.

Female Genitalia: Unknown.

Distribution ( Map 19 ): Glyphidocera lawrenceae is known from one collecting site in north­central Costa Rica, north of San José.

Etymology: Glyphidocera lawrenceae is named in honor of Linda H. Lawrence, former scientific illustrator, Systematic Entomology Laboratory, USDA, Washington, DC, and friend.
