New species and a redescription of species of Cloacina von Linstow, 1898 (Nematoda: Strongyloidea) parasitic in macropodid marsupials

Abstract

Four new species of strongyloid nematodes belonging to the genus Cloacina von Linstow, 1898 parasitic in macropodid marsupials are described and a poorly known species is redescribed from new material. Cloacina elegans Johnston & Mawson, 1938 is redescribed from the black-flanked rock wallaby, Petrogale lateralis Gould, from central Australia. Cloacina hylas sp. nov. from the stomach of the black-stripe wallaby, Notamacropus dorsalis (Gray), differs from congeners in lacking ornamented lobes surrounding the stoma, in the shape of the cephalic papillae, the presence of oesophageal bosses but the lack of oesophageal denticles. Cloacina idas sp. nov. from the stomach of Godman’s rock wallaby, P..
