This study elucidates the life-cycle of the reptile inhabiting nematode Abbreviata hastaspicula (Spirurida: Physalopteridae: Physalopterinae) in Australia. Eight Varanus gouldii (Lacertilia: Varanidae), and two Christinus marmoratus (Reptilia: Gekkonidae) lizards were captured in the wild. Two V. gouldii were used as controls and no experimental procedures were carried out on them. Another six V. gouldii (final host) and the two C. marmoratus (paratenic host) were treated with oral anthelmintics to remove all parasitic worms and were fed with infected live arthropods containing third stage larvae of Abbreviata hastaspicula. Faeces of V. gouldii were examined under the microscope weekly to determine whether the third stage larvae had developed into adults. Two months later, a total of 30 larvae and adults of A. hastaspicula were found in the stomachs of four experimentally-infected V. gouldii lizards. No cysts or larva were found in the C. marmoratus. This is the first study to demonstrate the life-cycle of this genus of nematode in their definitive reptile hosts.
