Heterodoxus spiniger was originally identified in Australia on the wallaby, but typically infests only canines. It is also the intermediate host to several helminth parasites of dogs including the tapeworm, Dipylidium caninumand the filarid nematode, Dipetalonema reconditum Price and Graham, Accessed Date Unknown at http: The lice may penetrate the blood vessels at base of feathers, leading to anemia. Journal of Helminthology The body is covered with small hairs called setae that help hold the louse on to its host.

In addition, Heterodoxus spiniger carries the filarid nematode Dipetalonema reconditumwhich parasitizes domestic dogs Price and Graham, Cuclotogaster heterographus Head-louse infests chickens on the skin and feathers of their head; sometimes extending onto the neck [5].
