Nematodes of the genus inhabit the large intestines or stomachs of macropodid (kangaroos and wallabies) and vombatid (wombats) marsupials. This study established the relationships of seven species of using mitochondrial (mt) protein amino acid sequence data sets. Phylogenetic analyses revealed that species of (, , , , and ) from the large intestines of their hosts formed a monophyletic assemblage with strong nodal support to the exclusion of from the stomach of the swamp wallaby. Furthermore, the mitochondrial protein-coding genes provided greater insights into the diversity and phylogeny of the genus ; such data sets could potentially be used to elucidate the relationships among other parasitic nematodes of Australian marsupials.
该属线虫寄生于袋鼠科（袋鼠和沙袋鼠）和袋熊科（袋熊）有袋动物的大肠或胃中。本研究利用线粒体（mt）蛋白质氨基酸序列数据集确定了该属七种线虫的关系。系统发育分析表明，寄生于宿主大肠的该属线虫物种（ 、 、 、 、 和 ）形成了一个单系类群，有很强的节点支持，将来自沼泽小袋鼠胃中的线虫排除在外。此外，线粒体蛋白质编码基因能更深入地了解该属的多样性和系统发育；此类数据集有可能用于阐明澳大利亚有袋动物其他寄生线虫之间的关系。
