European populations of the planthopper genus Ribautodelphax, comprising 5 known species and 3 undescribed Taxa of the R. collinus complex and two related species, were screened electrophoretically in order to clarify their taxonomic status and phylogenetic relationships. Pseudogamous triploid females occurring in populations of two species were investigated to assess their mode of origin. Allelic variation was scored at 10 presumed genetic loci. Nine loci proved to be polymorphic, one locus (Ldh) was expressed only in males and one locus (Pgi) was linked to the sex chromosome. Data on intraspecific and interspecific variability are presented. Genetic distance estimates were used to construct UPGMA and distance-Wagner trees. The species of the R. collinus complex clustered into one group with a subgroup consisting of R. imitans and Taxon 4 and the remaining species in the other subgroup. The two outgroup species are loosely appended to this R. collinus complex. Electrophoretic data of the pseudogamous triploid females are consistent with an autopolyploid polyphyletic origin.
