In its black thoracic stripes, penumbra agrees with vittula Loew, 
pedimculata Loew and incurva Loew, all being forms with the wings 
hyaline and not strongly infumed with brown as in penumbra. The 
lateral praescutal stripes are not incurved at the tip as in incurva 
and there is no black spot between the bases of the antennae as in 
pedunculata.

species of the genus Oropeza Needham.
