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, Petrogale godmani Thomas, differs from congeners in possessing a very slender oesophagus, eight leaf crown elements and the deirid in the anterior oesophageal region. Cloacina schultzi sp. nov. from the stomach of the yellow-footed rock wallaby, Petrogale xanthopus Gray, differs in possessing a sub-cylindrical oesophagus, a shallow buccal capsule and lip-like inflations of the leaf crown elements while Cloacina zetes sp. nov. from the stomach of the Western Australian tammar wallaby, Notamacropus eugenii (Desmarest), differs from all congeners in the shape of the leaf crown elements.

寄生在巨足类有袋动物中的 Cloacina von Linstow，1898（线虫纲：Strongyloidea）的新物种和物种重新描述

摘要 描述了属于 Cloacina von Linstow 属的四种新的类圆线虫，1898 年寄生在巨足类有袋动物中，并从新材料中重新描述了一个鲜为人知的物种。Cloacina elegans Johnston & Mawson, 1938 是根据澳大利亚中部的黑侧岩袋鼠 Petrogalelateralis Gould 重新描述的。Cloacina hylas sp。十一月 Notamacropus dorsalis (Gray) 与黑条纹袋鼠的胃不同，在造口周围缺乏装饰性裂片，呈头乳头状，存在食道隆起，但没有食道小齿。Cloacina idas sp。十一月 来自 Godman 的岩袋鼠的胃，Petrogale Godmani Thomas 与同类的不同之处在于拥有非常纤细的食道，八个叶冠元素和前食管区域的 deirid。Cloacina schultzi sp. 十一月 来自黄足岩袋鼠的胃，Petrogale xanthopus Gray，不同之处在于拥有亚圆柱形食道，浅颊囊和叶冠元素的唇状膨胀，而Cloacina zetes sp。十一月 Notamacropus eugenii (Desmarest) 来自西澳大利亚 tammar 小袋鼠的胃，其叶冠元素的形状与所有同类物不同。
