ABSTRACT A new species of the Subuluridae (Nematoda: Ascaridida) Labiobulura lengguruensis n. sp. is described from the caecum and colon and two new species of the Chabertiidae: Cloacininae (Nematoda: Strongylida) Paralabiostrongylus tuberis n. sp. and Dorcopsinema amplum n. sp. are described from the stomachof the macropodid marsupial Dorcopsis muelleri (Lesson, 1827) (Mammalia: Macropodidae) in Papua Indonesia. Labiobulura lengguruensis differs from all congeners in having a simple denticle associated with each labial lobe of the buccal capsule. Paralabiostrongylus tuberis can be distinguished from its congeners in by the position of the deirid and the form of the dorsal ray and genital cone. Dorcopsinema amplum can be distinguished from its congeners by the length of the spicule, the morphology of the appendages on the ventral lip of the genital cone, the position of the lateral branches of the dorsal ray, the shape of the female tail, the morphology of the vagina and the size of the eggs.The known nematode fauna of D. muelleri is summarised. The finding of three species of Dorcopsinema each in a different geographical locality suggests the possibility of allopatric speciation. A revised key to the species of Dorcopsinema is given.

来自印度尼西亚西巴布亚 Lengguru 的 Dorcopsis muelleri (Macropodidae) 的新种 Labiobulura（线虫：蛔虫），以及 Dorcopsinema 和 Paralabiostrongylus（线虫：Strongylida）

摘要 Subuluridae (线虫科：蛔虫) Labiobulura lengguruensis n. 的一个新种。sp. 从盲肠和结肠以及 Chabertiidae 的两个新物种中描述：Cloacininae（线虫：Strongylida）Paralabiostrongylus tuberis n。sp. 和 Dorcopsinema amplum n。sp. 描述于印度尼西亚巴布亚的巨足类有袋动物 Dorcopsis muelleri（课程，1827 年）（哺乳动物：巨足科）的胃中。Labiobulura lengguruensis 与所有同类的不同之处在于，其颊囊的每个唇叶都有一个简单的小齿。Paralabiostrongylus tuberis 可以通过 deirid 的位置以及背射线和生殖锥的形式与它的同类区分开来。Dorcopsinema amplum 可以通过针刺的长度与其同系物区分开来，生殖锥腹唇上附属器的形态，背鳍侧枝的位置，雌性尾巴的形状，阴道的形态和卵的大小。 已知的线虫动物群D . muelleri 进行了总结。在不同的地理区域发现了三种 Dorcopsinema，这表明存在异域物种形成的可能性。给出了 Dorcopsinema 物种的修订密钥。
