Abstract

Two new Pudicinae (Trichostrongylina, Heligmosomoidea, Heligmonellidae) coparasites of Proechimys longicaudatus (Caviomorph rodent) from Bolivia are described: Pudica ginsburgi n. sp. is differentiated from all the other species of the genus by the great length of the spicules and of the vestibule and by a different ratio of the length of the spicules on the length of the body. Heligmostrongylus chiarae n. sp. has very developed rays 4, strongly divergent from rays 5 as occurs in three other species, H. almeidai (Durette-Desset & Tcheprakoff, 1969), a parasite of Trichomys apereoides (= Cercomys cunicularius) from Brazil, H. squamastrongylus (Travassos, 1937), a parasite of Proechimys oris from Brazil and H. proechimysi Durette-Desset, 1970, a parasite of Proechimys semispinosus from Columbia. The specimens from Bolivia are differentiated from the three species by the division of the dorsal ray (anterior half versus posterior half) and by a different ratio of the length of the spicules on the length of the body.

摘要

描述了来自玻利维亚的长尾稻鼠（豚鼠型啮齿动物）的两种新的阴殖亚科（毛圆科线虫亚目，细颈线虫总科，细颈线虫科）共寄生物：金斯伯格阴殖线虫新种与该属的所有其他物种的区别在于交合刺和前庭的长度很长，以及交合刺长度与体长的比例不同。基阿拉细颈线虫新种的第4腹肋非常发达，与第5腹肋强烈分开，其他三个物种也是如此，即巴西的拟稻鼠（=穴居稻鼠）的寄生虫阿尔梅达细颈线虫（杜雷特 - 德塞特和切普拉科夫，1969年）、巴西的奥里斯稻鼠的寄生虫鳞腹细颈线虫（特拉瓦索斯，1937年）以及哥伦比亚的半棘稻鼠的寄生虫普氏细颈线虫（杜雷特 - 德塞特，1970年）。来自玻利维亚的标本与这三个物种的区别在于背肋的划分（前半部分与后半部分）以及交合刺长度与体长的比例不同。
