Dusky rat, Rattus colletti (Muridae), a new host for Echinoparyphium hydromyos (Trematoda: Digenea) in the Northern Territory, Australia

The digenean trematode Echinoparyphium hydromyos was recorded from the dusky rat, Rattus colletti, and the water rat, Hydromys chrysogaster, from the Adelaide River floodplain, Northern Territory, Australia. The dusky rat represents a new host for E. hydromyos and the Adelaide River floodplain is a new locality. This echinostome has previously been reported only from the water rat in southern and eastern Australia.
