(Figs. 120–122, 327, Map 22 View MAP 22 )

Diagnosis.— Glyphidocera plumae   is most similar to G. minarum   but differs from the latter by having a wider base of the digitate process of the valva, a narrower valval cucullus, and a smaller apical cornutus of the aedeagal vesica.

Description.— Head: Scales of vertex and frontoclypeus brown tipped with pale brown; outer surface of labial palpus pale brown intermixed with few brown scales, inner surface pale brown; scape pale brown intermixed with few brown scales, flagellum pale brown; male 4 th flagellomere not protuberant, 5 th and 6 th flagellomeres slightly excavated; proboscis pale brown.

Thorax: Tegula and mesonotum pale brown. Legs pale brown [many scales missing]. Forewing (Fig. 327): Length 7.6 mm (n = 1), pale yellow intermixed with pale brown and few brown scales. Undersurface pale brown. Hindwing: Pale brown.

Abdomen (Fig. 120): Male with 4 transverse, irregular rows of sex scales on intersegmental areas between terga 2–3 and terga 3–4. Sex scales between terga 2–3 appear equal in size as sex scales between terga 3–4.

Male Genitalia (Figs. 121–122): Uncus elongate, wide at base, broadly constricted above base, broadly rounded apically, apex acuminate and setose; gnathos setose, protuberant, wide throughout length, upturned apically; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing from posteroventral margin, and gradually widening to base of uncus; valva with costa straight from a shallow depression slightly beyond a slanted, basal, digitate process to apical furca; furca falcate, with a wide base; 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 a small conical, apical cornutus, with a large dilated and hollow, basal cavity.

Female Genitalia: Unknown.
