This study examined genetic variation within and among species of Cloacina found in the common wallaroo (Macropus robustus) collected at different localities from mainland Australia, and evaluated geographical distance as a potential driver for genetic variation. The first and second internal transcribed spacers (ITS-1 and ITS-2=ITS) of nuclear ribosomal DNA were used to characterize individuals of 17 morphospecies of Cloacina that parasitize Macropus robustus and its sub-species. Results revealed intraspecific variation in ITS within some morphospecies of Cloacina. Phylogenetic analyses showed little correlation between host speciation patterns and geographical location for the majority of ..View full abstract
