15-16mm. This species is similar to eudoxusalis as indicated above, but with a paler, more ochreous ground colour to the wings. The male genitalia are very similar but the new species has more rounded valve apices than eudoxusalis, and the spine-like apex of the costa extends for a much shorter distance beyond the valve apex. The patch of coarser spines in the aedeagus vesica is less extensive but is accompanied by a diverticulum free of scobination just distal to it. In the female, the ductus bursae is shorter relative to the corpus bursae than in eudoxusalis, and the corpus bursae is wider distally rather than centrally, with the basal zone of scobination terminating centrally rather than at a point just distal to the centre.
