Genetic variation in Austrostrongylus thylogale Johnston & Mawson, 1940 (Nematoda: Trichostrongylida) from the tammar wallaby, Notamacropus eugenii (Gray), and the quokka, Setonix brachyurus (Quoy & Gaimard) (Marsupialia: Macropodidae) in Australia.

This study provides evidence of genetic variation within A. thylogale based on collections from two different host species. Morphological studies are required to fully confirm the presence of a new species or cryptic species. Further molecular studies using a larger number of specimens are warranted to explore the genetic variation between A. thylogale from different geographical localities.
