摘　　要：奥斯特亚科(Ostertagiinae)的线虫是反刍动物最常见的圆线虫种类之一。过去几十年来,该亚科线虫分类学研究的进展在国内知之甚少。论文从比较形态学和分子学研究方面介绍奥斯特亚科线虫中雄虫的多态性、隐藏种等现象。种的多态性存在于奥斯特亚科中的马歇尔属(Marshallagia)、背板属(Teladorsagia)、刺翼属(Spiculopteragia)、奥斯特属(Osterragia)和奥洛夫属(Orloflia),隐藏种主要存在于背板属。奥斯特亚科中出现的这种现象,使毛圆科线虫种的鉴别变得困难和复杂化。因此,有必要在我国收集和研究这个亚科中有效且具有可比性的生物多样性数据。Nematodes of the subfamily Ostertagiinae are one of most common species of the strongyles in ruminants.Over the past decades,few people know about the progress in the study of taxonomy of nema- todes of the subfamily in our country.In this paper,from comparative morphology and molecular aspects, we introduced the phenomenon of male polymorphism, cryptic species and so on.Species polymorphism ex- ists in Marshallagia, Teladorsagia, Spiculopteragia, Osterragia and Orloflia of the Ostertagiinae, while cryptic species mainly exist in the genus Teladorsagia.The phenomena occurring in the members of the Ostertagiinae can lead to the difficulty and complexity of species identification for nematodes of the Tricho- strongylidae.Therefore, it is necessary to collect valid and comparable data on the biodiversity of this family in our country.
