Dyrzela roseata sp. n.


Dyrzela roseata



17mm. The antennae are ciliate. The appearance is much as in D. plagiata but the forewings are a pale roseate brown with transverse fasciae obscure, scales towards the base of the wing coarse. The basal part of the anal vein is associated with a large fovea, running round its posterior side and, on the underside, giving rise to a tuft of long yellow scales that lies within the fovea. The fovea causes the vein systems anterior to it to arch concavely round it. The dorsum is strongly convex. The anterior and basal part of the hindwing lacks normal scales, but has the two areas interact. The hindwing is more triangular than in other species, and there is some distortion of the venation. In the abdomen the features of the eighth sternite and genitalia are typical of the genus except the slender saccus is absent. Both the costal process and the clavus of the valve are large, broad. The valve is constricted at two thirds, the apex slightly bibbed, with lobes setose, the upper lobe with longer, thicker setae arranged marginally in what may be a modified corona.
