Diagnosis. Imagos are superficially similar to Pseudotelphusa fuscopunctella (Clem.) but differ by having the transverse median fascia confluent with the postmedian fascia on the forewing. Arcutelphusa talladega can be distinguished from other Teleiodini by having the costal part of the valva sickle shaped and strongly bent at its middle.
