Redescription. Male. Length of fore wing 12‒15 mm; antenna bipectinate, setae short, antenna equal to ½ of fore wing in length. Thorax and abdomen densely covered with light-brown scales. Fore wing light-brown with pattern: dark-brown strokes along costal edge, transverse wide dark-brown postdiscal band, small hardly visible brown spots throughout all wing area, fringe mottled (brown at veins, yellow between veins). Hind wing lightyellow, without pattern, fringe yellow, fringe brown only at distal tip of veins Sc, CuA 2, 1A+2A.

Male genitalia. Uncus long, thin, distal tip with lobe-like extension, small incisure apically; tegumen cylindrical; valva with convex costal and abdominal edge, narrowing in distal third, outer edge trapezoidal, inner surface of valva with small fold, semicircular harpe with wide base on sacculus; juxta lamellar with ring-like aperture; saccus semicircular, weakly pronounced; phallus equal to 1/2 of valva in length, slightly curved throughout full length, narrowing to apex, apex with small spiky process, vesica without cornuti.

Female. Length of fore wing 16‒19 mm. Antenna bipectinate, setae short, antenna equal to 1/2 of fore wing in length. Thorax and abdomen densely covered with light-brown scales. Wing pattern similar to that of male.

Female genitalia. See the genus redescription above.

Diagnosis. The species clearly differs from others by well modified pattern on the fore wing, lobe-like distal extension on uncus and special shape of valvae.

Distribution. Argentina, Paraguay.
