Xyleutes Hübner

Taxonomic note

Schoorl (1990) restricted this genus to strix Linnaeus, persona le Guillou, and keyensis Strand (Kai, Tanimbar, ?New Guinea). It is defined on elevation of the frons, very short marginal fringes to the wings and the relative size of two sclerites at the base of the forewing (a large humeral plate). The two species in Borneo have an elongate black mark at two thirds from the base of the forewing, just at the apex of the cell. Schoorl noted a larval host record of Sesbania (Leguminosae) for strix.
