16mm. The wings are somewhat diaphanous, with a
sparse and irregular scattering of the broader scales in striae. There is a
small black discal spot on the forewing. The frons is broadly pinkish rufous
below the line of the antennae, with a white triangle notching this area
ventrally, or with a more restricted area of white. The palps grade ochreous
yellow towards the apex. The legs are not spotted. The male genitalia have the
uncus broad, bilobed and darkly rugose, a unique feature in the genus. The pair
of lateral processes of the aedeagus are well developed, the valves rectangular
with the apical margin slightly concave and a long straight, slender harpe that
extends just beyond the apex.
