ABSTRACT Three species of Parastrongyloides previously described from the small intestine of Australian marsupials are reviewed and redescribed from new material and in some instances new host species: P. australis Mawson, 1960 from Isoodon obesulus and Perameles gunnii; P. peramelis Mackerras, 1959 from I. macrourus, Perameles nasuta and Perameles gunnii; and P. trichosuri Mackerras, 1959 from Trichosurus vulpecula vulpecula, T. vulpecula johnstoni and Petaurus breviceps. In addition, three new species of Parastrongyloides Morgan, 1928 (Nematoda: Rhabditoidea: Strongyloididae) are described from the small intestines of their hosts: P. nadgeensis from the agile antechinus, Antechinus agilis, the dusky antechinus, A. swainsonii, and the fat-tailed dunnart, Sminthopsis crassicaudata; P. timbillicensis from the white-footed dunnart, S. leucopus and S. crassicaudata; and P. walterae from the small intestine of A. swainsonii. Three additional suspected species are partially described from the southern long-nosed bandicoot, P. nasuta; the northern quoll, Dasyurus hallucatus; and the little-long-tailed dunnart, S. dolichura but not named. A key to the species of Parastrongyloides from Australian marsupials and a monotreme is presented.

对澳大利亚有袋动物的副类圆线虫（线虫科：线虫科：圆线虫科）物种的回顾，并描述了三个新物种

摘要 对先前从澳大利亚有袋动物小肠中描述的三种副类圆线虫进行了回顾和重新描述，在某些情况下是新的宿主物种：P. australis Mawson，1960 来自 Isoodon obesulus 和 Perameles gunnii；P. peramelis Mackerras，1959 年来自 I. macrourus、Perameles nasuta 和 Perameles gunnii；和 P. trichosuri Mackerras，1959 年来自 Trichosurus vulpecula vulpecula、T. vulpecula johnstoni 和 Petaurus breviceps。此外，1928 年从宿主的小肠中描述了 1928 年摩根副圆线虫的三个新物种：来自敏捷 antechinus 的 P. nadgeensis、Antechinus agilis、暗色 antechinus、A. swainsonii 和脂肪-tailed dunnart, Sminthopsis crassicaudata; P. timbillicensis 来自白脚杜纳特、S. leucopus 和 S. 草本植物；和来自 A. swainsonii 小肠的 P. walterae。从南部长鼻袋狸 P. nasuta 中部分描述了另外三个疑似物种；北袋鼬，Dasyurus hallucatus；和小长尾杜纳特，S. dolichura，但未命名。介绍了来自澳大利亚有袋动物和单孔目动物的副类圆线虫物种的关键。
