Diagnosis. Entirely white with a slight ochreous tinge, veins slightly darker than foreground. Below a black streak along the costa of forewings and the veins more contrasting in the distal part of wings. Females larger than males.

Description. Male. Head. Proboscis light beige. Palpi entirely covered with white scales. Frons and vertex dirty white. Antennae bipectinate, scape and shaft dorsally covered with white scales but ventrally the shaft and pectinations are dark brown. Body and wings. The whole body and wings are entirely white with a slight ochreous tinge. Forewing length 11‒12 mm (n = 2). The veins appear slightly darker than foreground. There is a slight ochreous spot at the end of forewing cell. Collar, thorax and abdomen concolorous with wings. Fringes of the wings white. Ventrally the markings are more contrasted. There is a black streak along the costa of forewings and the veins are more contrasting in the distal half of all wings, also a thin black line on the outer margin more distinct near apex. Ventral part of thorax and abdomen white, the collar appears yellowish. Genitalia ( Figs. 35‒38 ). Uncus cylindrical slightly spatulate in the terminal half and with a sharp spine on tip. Above uncus two symmetrical processes, tongue shaped, reaching the middle of uncus. Valvae subrectangular, long and narrow reaching the tip of uncus. The tip well sclerotized, pointed and bent inwards. A small translucent cucullus covered with hairs in ventral position. A triangular process pointing internally just beyond the middle of valvae. Vinculum wide with rounded and triangular saccus well developed. Juxta extended, sclerotized and shaped as Λ. In lateral view the genitalic capsule appears extremely flat. Phallus cylindrical, slightly sinuate, long and narrow. Vesica with a unique and large ventral lobe with longitudinal wrinkles and two patches of cornuti: an ovoid and dense patch of small spines near entry and a longitudinal row of small spines on the total lobe.

Female. Identical to male but slightly larger. Forewing length 13 mm (n = 2). Antennae ciliate. Genitalia ( Fig. 52 ). Genitalia generally slightly sclerotized, apophyses anteriores and posteriores subequal, thin and long. Ductus bursae as a narrow cylindrical tube strongly bent and sinuous in the last third where it is strongly sclerotized. Bursa copulatrix large and pyriform, strongly sclerotized at the narrow end near the junction with ductus bursa. The bursa is entirely covered with spicules on the basal two thirds of the length, the last distal third being smooth and the ductus seminalis emerges laterally in that area.

Barcode. See Discussion.

Biology. Unknown.

Distribution. BRAZIL, PARAGUAY, ARGENTINA.
