7mm. This and the next
species are closely related, but with somewhat similar facies to uniformis. They
differ in that the males have ciliate antennae and a paler zone on the dorsal
half of the hindwing, in this species distinctly rufous. They share features of
the male abdomen such as conspicuous brushes of narrow scales in the
intersegmental membrane between the eighth segment and the genitalia, and rather
trapezoid valves with bilaterally asymmetric processes subbasally on the valve
costa. This species has the asymmetry more pronounced, the left process larger
and both directed more away from the valve. The apices of the valves also
differ, the left with only a costal lobe, the right with a more ventral one as
well. The aedeagus vesica has two distinct, tight groups of narrow spines.
