title: Durettechina beveridgei n. g., n. sp. (Nematoda: Seuratidae) from Antechinus spp. (Dasyuridae: Marsupialia) from Australia.
abstract: Durettechina beveridgei n. g., n. sp. (Nematoda: Seuratidae) is described from Antechinus flavipes (Dasyuridae) from Victoria and New South Wales. A single female from A. bellus from the Northern Territory may also be D. beveridgei. This new genus is compared with other genera of the Echinonematinae, to which it has been assigned. The genus has a unique body armature and most closely resembles Chabaudechina, in the armature of the cephalic bulb, but has four rather than five rows of hooks, and Linstowinema, in having body hooks on the cuticle of the anterior region, but has 18-22 hooks in each row rather than 14-16. The hooks of Durettechinca are also smaller and have a less complex root morphology than those of Linstowinemna. Durettechina resembles Seurechinac and Chabaudechina in having caudal alae into which papillae extend, but differs from both these genera in the number and arrangement of the caudal papillae, as well as in the body armature. Durettechina, is most different from Bainechina, which has neither hooks on a cephalic bulb nor body hooks on the anterior region nor caudal alae.
