Diagnosis. The forewing length is 7.5–10.5 mm. The maculation is dull orange with scattered black scales, with faint antemedial and postmedial lines; males ( Fig. 2–4 ) have a faint gray-black antemedial spot that is not developed in females ( Fig. 5 ). The gnathos of the male genitalia ( Fig. 28–30 ) curves evenly into a narrow, dorsally directed hook; the narrow distal part of the hook is as long as the base of the gnathos. The end of the sacculus ( Fig. 12–13 ) is not strongly projected, so the distal margin of the valva is evenly rounded, not truncate. The corpus bursae ( Fig. 50–55 ) is rather elongate, without constriction between the anterior and posterior lobes; the ductus bursae is dilated more than half of its length, nearly to the posterior end of the corpus bursae, which it parallels closely. There is a long row of spines on the wall of the corpus bursae nearest to the ductus bursae, another row in the ductus bursae facing the corpus bursae, and a few in the anterior angle of the corpus and ductus bursae. The posterior margin of the antrum ( Fig. 68 ) is thickened and transversely straight, with slender lateral angles that are wider than the ductus bursae.

Material examined. Years of collection follow the specimen count. Specimens are in the FSCA and MGCL unless noted.
