Description of Buckarootrema goodmani n. gp., n. sp (Digenea : Pronocephalidae), a parasite of the freshwater turtle Emydura macquarii (Gray, 1830) (Pleurodira : Chelidae) from Queensland, Australia, and a phylogenetic analysis of the genera of the Pronocephalidae Looss, 1902

Buckarootrema goodmani n. g., n. sp. is described from the small intestine of the Murray turtle, Emydura macquarii (Gray, 1830), from the vicinity of Warwick, Queensland, Australia. The distinctive taxonomic features include the vitellarium, which consists of 2 compact masses directly anterior to an d occasionally overlapping the testes; the uterus with extensive pre- and p ostovarian coils; intestinal ceca with small, medial diverticula that termi nate anterior to or at the anterior margin of the testes; a comma-shaped ci rrus sac with both internal and external seminal vesicles. Phylogenetic sys tematic analysis of the genera of the Pronocephalidae including Buckarootre ma and Notopronocephalus, the only other genus of pronocephalids reported f rom Australian freshwater turtles, indicates that Buckarootrema is the sist er taxon of Neopronocephalus and Notopronocephalus is the sister group of t he rest of the Pronocephalinae.
