Udea exigualis (Wileman): Inoue 1982: 364.

Diagnosis.

This species is similar to other species of Udea lugubralis -complex. It can be distinguished from Udea lugubralis by smaller size (wingspan 16-21 mm) and longer harpe with sharp point. It differs from Udea stationalis and Udea montensis by bent harpe with sharp point. Its phallus apodeme lacking a small lateral tooth-like process is different from Udea montensis . Udea exigualis is similar to Udea ferrugalis and Udea testacea (Butler) with yellowish-brown forewing bearing dark brown fringe, but can be distinguished in male genitalia by the more slender and shorter fibula and the juxta without dorsal arms.
