Reddish-orange. Half of the anterior margin brown. Posterior margin with few leaden scales. Termen brown. Veins partly covered with brown scales. A rhomboid orange spot, delimited by an antemedial and a medial band, both formed by reddish and leaden scales. The medial band projects to the junction of M 3and Cu 1. Two well defined spots in the discal cell. A subproximal ovoid white spot at M 2-M 3. With Scattered patches of orange, reddish, and leaden scales towards the outer margin area. Ventral.

Tegumen narrow sided, its anterior margin shaped as an inverted “U”. Uncus base as wide as the distal part of the tegumen; near its base, two curved “˩”-shaped, sclerotized lateral processes, with abundant long and thick bristles at the base; distal part short, pointed and hook shaped at its end, a concave notch on its ventral part. Valva. Lateral view: wide at the base, quadrangular, with a concave notch at the base of the ventral margin; ventral process membranous with setae; dorsal process sclerotized, wide, elongate, curved at the dorsal margin; ventral margin concave with a pronounced subdistal notch, distal end slightly wider. Ventral view: subproximal concave margins; diverging obliquely towards the dorsal process at the distal half; dorsal processes curved towards the mesal margin with wider ends. Juxta sclerotized, wide, pentagonal: with membranous areas, anterior side, small and digitiform; posterior side, a large round concavity. Transtilla sclerotized, wide, elongate, pointed at the dorsal posterior part. Aedeagus elongate and sinusoidal; coecum penis elongate; vesica short, membranous, with an elongate dorsal process and a digitiform ventral process; with minute spicules at the dorsal area.  Female. Unknown   Etymology. tarisca is a Quechua adjective, used as a feminine adjective in the nominative singular, which means “the discovered one”.   Distribution.
