Australian hookworms (Ancylostomatoidea): a review of the species present, their distributions and biogeographical origins.

Ancylostomatoidea or hookworms recorded in Australia are reviewed and the attempt is made to provide the biogeographical background to their occurrence. The poor representation of this nematode superfamily is probably a reflection of the fact that they are primarily parasites of Carnivora, Artiodactyla, Insectivora, Rodentia, Edentata, Proboscoidea and primates, eutherian mammals which are either absent from the Australian fauna or which have only recently reached the continent. The principal genera of hookworms recorded to date from Australia are Ancylostoma, Bunostomum, Necator and Uncinaria. The majority of the ancylostomatoid fauna is represented by introduced species of man and domestic animals. Native or endemic species of hookworms are restricted to members of the genus Uncinaria with two species occurring in rodents and pinnipeds. Only a single endemic species of hookworm is known, U. hydromyidis, which is found in the small intestine of a rat. Significant problems remain in understanding the systematics, epidemiology and evolutionary relationships of the Australian ancylostomatoid fauna.
