Diagnosis.
Forewing length
14 mm
; wings light brown, with transversal bands: a V-shaped narrower subbasal band, a V-shaped wider antemedial band (joining by its angle with the discal bracket), a curved and narrow postmedial band with a concavity between veins M1 and M2; apical stroke directed towards vein M2, and several marginal spots in internervular spaces, those between veins M1 and M3 being the largest; hindwings lighter than forewings, with single discal spot.
Male genitalia
(
Figs. 9, 11
): Uncus long and straight, apically enlarged and bifurcated, with additional subapical hook-like arms directed proximally; cucullus of valves with apical enlargement of a crescent shape; distal angle of its external concavity acute, the basal one rounded; sacculus membranous, crescent-shaped, covered with short hair; saccus short and broad; aedeagus simple, lacking spines, straight or slightly curved; vesica bag-like, covered by small spiniculi.
Remarks.
By wing pattern the
type
species is similar to the next species but the ground colour is more brownish, the antemedial band partly joined with a hind half of the discal bracket. The male genitalia structure is characteristic to the species: it has long and strongly curved lateral subapical processes of the uncus, a crescent-like cuculus apex with an acute distal angle; the sacculus is crescent-shaped.
