Two new species of nematodes of the genus Cloacina (Strongyloidea: Cloacininae) parasitic in the stomachs of red kangaroos, Osphranter rufus (Marsupialia: Macropodidae)

Abstract

Two new species of Cloacina (Nematoda: Strongyloidea) are described from the stomach of the red kangaroo, Osphranter rufus. Cloacina xericola sp. nov. is described from a single locality, Menzies, in Western Australia. It differs from all congeners in having a highly recurrent vagina, six leaf crown elements, a lack of bosses in the lining of the oesophagus and extremely long spicules. Cloacina eris sp. nov. is most closely related to C. ares Beveridge, 1998 in the features of the buccal capsule and oesophagus, but differs in the position of the deirid, being posterior to the nerve ring in the new species, as well as in the form of the spicule ala which diminishes towards the tip in the new ..
