Although Schmidt-Rhaesa (2002) notes that seven Nematomorph species are recorded for Australia, but he lists eight species. Two further species were described by Schmidt-Rhaesa and Bryant (2004), bringing the total to ten.
These curious parasitic worms, known as 'Horsehair Worms' or 'Gordian Worms' are parasites of arthropods, including spiders, beetles and mantids (Schmidt-Rhaesa 2001) and vertebrates such as fishes and frogs. The life cycle of species that parasitise praying mantids is described by Schmidt-Rhaesa (2001). The Australian Museum website has an interesting account of these worms.
