A new species of Neoheterocotyle Hargis, 1955 (Monogenea: Monocotylidae) from the gills of Pristis clavata Garman (Pristidae) from Darwin, Australia

Neoheterocotyle darwinensis n. sp. is described from between the secondary gill lamellae of the dwarf sawfish Pristis clavata Garman (Pristidae) collected at the mouth of Buffalo Creek near Darwin, Northern Territory, Australia. This is only the second monocotylid species to be described from northern Australia. N. darwinensis is distinguished from the other seven valid species in the genus by the morphology of the hamuli, the dorsal haptoral accessory sclerites and the male copulatory organ. The similarities between N. darwinensis and Nonacotyle pristis Ogawa, 1991 from the gills of the freshwater sawfish Pristis microdon Latham collected in Papua New Guinea are discussed.
