Barker 1999a distinguished this species from the very similar D. leucosticta by its dark green head and pronotum (cf. bronze-green or coppery), black elytra (cf. brown or bronze) and narrower and parallel-sided aedeagus (cf. wider and rounded).
Very closely related to D. leucosticta and only known from the type collections comprising three specimens taken at Melrose in the southern Flinders Ranges in 1978 and 1986.
