Phylogenetic and morphological discord indicates introgressive hybridisation in two genera of Australian millipedes (Diplopoda, Polydesmida, Paradoxosomatidae).

ABSTRACT: Discord between molecular and morphological datasets was observed in two pairs of species of Australian millipedes in the family Paradoxosomatidae using morphological and molecular phylogenetic analysis (mitochondrial COI rDNA and 16 rRNA, and nuclear 28S rRNA). Close to the presumed distributional boundary between Pogonosternumnigrovirgatum (Carl, 1912) and Pogonosternumjeekeli Decker, 2017, near Dargo in Central Gippsland, Victoria, Pogonosternum specimens were collected which are phylogenetically closer to P.jeekeli in COI and 16S sequences, but are morphologically closer to P.nigrovirgatum. At Mount Osmond, Adelaide, South Australia, eight morphologically typical Somethuscastaneus (Attems, 1944) specimens were collected are phylogenetically clo
