Three new species of strongyloid nematodes from Thylogale stigmatica (Gould, 1860) and Thylogale thetis (Lesson, 1828) (Marsupialia : Macropodidae)

Thylonema woodalli sp, nov. is described from the stomach of the pademelons Thylogale stigmatica and T. thetis from Queensland. Thylonema woodalli dif fers from congeners in the shape of the buccal capsule. Thylonema clelandae sp. nov. is described from the stomach of, the pademelon, Thylogale stigma tica. Thylonema clelandae differs from congeners in the shape of the buccal capsule, the sclerotised folds in the oesophageal bulb, lip-like structure s in the buccal capsule and lack of an annulus in the wall of the buccal ca psule. Thylostrongylus franklinae sp. nov. is described from the stomach of the pademelon, Thylogale stigmatica from Queensland. It differs from conge ners in the proportions of the buccal capsule, the prominence of striations of the buccal capsule, spicule length, the origin of the dorsal ray and ov erall size.
