Gentiliocossus Yakovlev, Naydenov et Penco , gen. n.

Type species (designated here) — Gentiliocossus alexi Yakovlev, Naydenov et Penco , sp.n.

DESCRIPTION. Male. Moths of medium size. Antenna bipectinate, short (1/3 of fore wing in length). Fore wing wide, apically rounded, brown, with pattern of wide rounded brown and ocher portions and bands. Hind wing grey, without pattern.

Male genitalia. Uncus of medium length, gradually narrowing from base to apex; gnathos arms short; gnathos absent; valve wide, apically semicircular, directed ventrally; saccular edge with more or less expressed notch; small harpe in proximal part of valve; juxta very robust, with wide leaf-like lateral processes; saccus elongated; phallus slightly narrowing from base to apex, of various shapes.

Female unknown.

DIAGNOSIS. The new genus clearly differs from the other Hypoptinae representatives, its main external characteristic feature is the wide rounded brown portions and bands. In the male genital structure, the genus is most close to the genera Philanglaus Butler, 1882 and Philiodoron Clench, 1957 . From the specimens of the genus Philanglaus the new genus differs in the absence of the long smooth harpes at the base of the valve. From the genus Philiodoron it differs in the laterally diverged valves (in Gentiliocossus the valves are directed ventrally).

COMPOSITION. The genus includes three species: G. alexi Yakovlev, Naydenov et Penco , sp.n., G. caimancito Yakovlev, Naydenov et Penco , sp.n. and G. vogli Yakovlev, Naydenov et Penco , sp.n.

DISTRIBUTION. Argentina (Jujuy Province), Venezuela (Aragua State).
