Tegmina hyaline, fuscous brown, lighter over basal half, dark over apical half, especially distad of clavus; a triangular, lighter mark at end of costal cell and a smaller spot at apex of each apical cell, a small dark spot at apex of claval margin, rest of claval margin white or yellowish white; veins closely studded with black granules; wings hyaline, veins dark. Pygophor slightly compressed laterally, ventral edge medially produced into a small plate which is bifid at apex; at each side of base of plate the pygophor is slightly depressed; anal segment with a long, thin, inwardly curved spine from each ventral corner, spines reaching across pygophor; genital styles small, basal portion spindle-shaped, slightly flattened, apex drawn to a point which is at right angles to basal portion. Length, 2.7 mm; tegmen 4.
