15-16mm, 14mm. The facies is similar to that of
vialis but the greenish brown is darker on the forewing, and the hindwing
border is broader, with the basal pale area suffused dull brownish. The forewing
discal spot is more clearly defined and distinctly ochreous. The sexual
dimorphism is similar to that of vialis. In the male genitalia the right
saccular process has a much more extensive zone of curvature basally and is
upcurved rather than downcurved at the apex. The left process is sinuous,
expanded at the apex but not bifid as in the rest of the vialis group.
The aedeagus is much as in vialis.
