A recent Dreissenid molecular phylogeny using COI and 16S sequences (Therriault et al. 2004) concluded that Dreissena bugensis and D. rostriformis actually represent distinct races of a single species (sequence divergence was 0.23 - 0.54%, comparable to intraspecific variability in other species). The authors recommended the ancestral name D. rostriformis be used, with two races, bugensis and distincta (Therriault et al. 2004, Orlova et al. 2005). However, there is still confusion over this.

This species is also regarded by some as a subspecies of the invasive Zebra Mussel D. polymorpha (M. Seddon pers. comm. 2009).[1].
