Type species (by monotypy) Philanglaus ornatus Butler, 1882
REDESCRIPTION. Size medium (length of fore wing 17–21 mm). Antenna bipectinate; in males — crest processes three times longer than antenna rod diameter, in females — 1.5 times longer than antenna rod diameter. Wings light-brown from above, fore wing with contrast pattern of bright brown undulated bands and spots. Hind wing light-brown with poorly expressed pattern.
Male genitalia ( Figs 6–7 View Figs 6–7 ). Uncus long, robust; gnathos arms ribbon-like, short, not fused; gnathos reduced; valve short, apically semicircular; costal edge basally with long harpe gradually narrowing from base to apex; juxta scaphoid with two robust sickle-curved lateral processes apically extended and bent; saccus robust, pyramidal; phallus thin, slightly shorter than valve, slightly curved, vesical aperture in dorso-apical position, vesical without cornuti.
DIAGNOSIS. The genus Philanglaus Butler, 1882 is morphologically close to the genera Hypopta Hübner, 1818 and Laberlia Yakovlev, Naydenov & Penco, 2020 from which it differs in the bright contrast pattern of the fore wing, and the relatively smooth edged of the harpe. The apomorphies of the genus are the sickle-curved lateral processes of the juxta with expended curved apices.
COMPOSITION. Two species: Philanglaus ornatus Butler, 1882 and Philanglaus xylodopoecila ( Zukowsky, 1954) comb.n.
DISTRIBUTION. Southern Peru and Chile.
