Identification
E. fimbriatus can only be distinguished from E. interruptus by a notch in the aedeagus, which requires dissection. Since the northeast containes both species, ID from photos is not recommended. Head coloration can be valuable for ID, but is both sexually dimorphic and varies by region in this genus. (Comment by Andrew Short on #116800)
