The melanic colour form of D. ferrugatus , described by Konow as D. thomsoni var. miricolor , has sometimes been mixed up with D. pachycerus Hartig, 1837. Apart from their different penis valves, they can be separated by the shape and the structure of the mesoscutellar appendage: long, concave at the sides, and with a distinct longitudinal keel in D. pachycerus compared with D. ferrugatus .
