Glyphidocera staerae , new species

(Figs. 177–179, 346, Map 32)

Diagnosis.— Glyphidocera staerae is most similar to G. c a v e a e but differs by having a narrower digitate process of valva, more narrowly separate costal furcae of the valva, a narrower cucullus, and a longer and more narrow apical curnutus of the aedeagal vesica.

Description.— Head: Vertex and frontoclypeus pale yellow; outer and inner surfaces of labial palpus pale yellow; scape of antenna pale yellow intermixed with few pale­brown scales, flagellum pale yellow; 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 yellow.

Thorax: Tegula and mesonotum pale yellow. Legs pale yellow. Forewing (Fig. 346): Length 6.9 mm (n = 1), pale yellow intermixed with few pale­brown scales; cell with 3 spots; 1 near midcell and 2 on distal end near and parallel with crossvein. Undersurface pale yellow. Hindwing: Pale yellow basally, gradually darkening to apex.

Abdomen (Fig. 177): Male with two irregular rows of sex scales on medial intersegmental membrane between terga 2–3, and with three transverse, irregular rows of sex scales between terga 3–4.

Male Genitalia (Figs. 178–179): Uncus elongate, wide at base, broadly constricted near midlength, triangular­shaped apically, apex setose, acuminate, and recurved; gnathos protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent from a wide base, fusing dorsally, extending to base of uncus; costa gradually upturned from a shallow depression beyond a basal digitate process to dorsal furca; apex bifurcate, dorsal furca pointed and three times longer than ventral furca; ventral furca with a rounded apex; base of costa bearing a long, stalked, slightly curved, digitate process; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate and broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus denticulate, bearing an elongate, apical cornutus; cornutus with one side shortened near midlength, exposing a hollow, basal cavity.

Female Genitalia: Unknown.
