Linstowinema breve n. sp. (Nematoda: Seuratidae) a parasite of Antechinus agilis (Marsupialia: Dasyuridae) from Australia.
A new echinonematine nematode, Linstowinema breve sp. n., from the small intestine of the dasyurid marsupial Anthechinus agilis is described. The species is distinguished from its congeners by the possession of the following suite of characters: small size; first and third row of cephalic hooks similar in size; second row larger; 13-15 rows of body hooks without undulating edges on the dilated cuticle of the oesophageal region; oesophagus terminating at the level of the 5th-7th row of body hooks; ten pairs of caudal papillae; a large pair of lateral ad-cloacal papillae extend into small lateral alae. Linstowinema larvae previously recorded from A. agilis may be the same species. A key to species of the genus linstowinema is provided.
