This genus is also similar to the Pomponia linearis species group, but it can be distinguished from the latter by the following characters: hind wing with zigzag infuscation along bases of apical cells 1 – 3; male abdomen widest across abdominal segment 4; and basal lobe of pygofer absent ( Lee 2012b ) or short; uncus bifurcate, forming a pair of uncal lobes.
