Abstract

A new species of filarioid nematode of the genus Breinlia Yorke & Maplestone, 1926 (Nematoda: Filarioidea) is described from rodents in Lao PDR and according to its morphology, is placed in the subgenus Breinlia. Breinlia (Breinlia) jittapalapongi n. sp. occurs in the Asian house rat (Rattus tanezumi Temminck) and the Sikkim rat (Rattus andamanensis Blyth) and is reported from two localities (Luang Prabang and Champasak). The new species can be distinguished from all other congeners, which are mostly distributed in Australasia (twenty-two species), South East Asia (four species) and India (two species), by the following characters of the males: shape and size of gubernaculum, length of spicules, pattern of cloacal papillae and presence of sclerotised ring in the buccal capsule. This is the fifth species of Breinlia described from South East Asia.

摘要

1926年，约克和马普尔斯通首次描述了布氏丝虫属（Breinlia Yorke & Maplestone, 1926）的一种新的丝状线虫（线虫纲：丝虫总科）。该线虫发现于老挝人民民主共和国的啮齿动物体内，根据其形态学特征，被归入布氏丝虫亚属。新物种布氏丝虫（布氏丝虫亚属）jittapalapongi n. sp.寄生于亚洲家鼠（Rattus tanezumi Temminck）和锡金大鼠（Rattus andamanensis Blyth）体内，在老挝的琅南塔和占巴塞两个地区被发现。该新物种可通过雄虫的以下特征与所有其他同属物种区分开来，其他同属物种大多分布在澳大拉西亚（22种）、东南亚（4种）和印度（2种）： gubernaculum的形状和大小、交合刺的长度、泄殖腔乳头的排列方式以及口腔胶囊中是否存在硬化环。这是在东南亚描述的第五种布氏丝虫。
