8mm. This species is similar to rentoni in general form and colour, except the head and appendages are more uniformly brown with the forewings and thorax. The forewings are less heavily invested with mauve markings, and the discal area is a darker brown. The postmedial is much more broken, obscure and irregular in course, the pale spots surrounded narrowly with black. There are pale striae on the distal half of the costa, but these are not so conspicuous. The marginal patches are similarly obscured, regular in size, and set in from the margin slightly. The hindwings on the underside are more distinctly paler than the forewings compared to rentoni, but the fasciation is similar. The abdomen is distinct from that of rentoni and innotabilis in having shallower coremata on the fifth and sixth sternites, those on the former larger and flanking a pair of convergent setose pads centrally. The eighth segment is of a more typical framed corematous form. The genitalia have a more robust uncus, a wider basal separation of the more tongue-like valves, and a much smaller saccus. The aedeagus is relatively large, and the vesica is more finely scobinate..
