Note: D. r. tenuis and D. r. subrubicundus are considered as either subspecies or morphs of D. rubidus . D. r. tenuis is thought to be the parthenogenetic race of D. rubidus rubidus ( Csuzdi, Zicsi, 2003) , while D. r. subrubicundus has certain morphological differences from the nominative subspecies. These taxa occur in sympatry, and so do not comply to the definition of subspecies ( Mayr, 1982). In addition, both our data and the analysis of Csuzdi et al. (2017) demonstrated that there are no genetic differences between these taxa. Thus we do not treat these taxa as subspecies.
