Anoplocephalid cestodes have a worldwide distribution, but relatively few species are known from South American rodents. By examining the collections of the Harold W. Manter Laboratory of Parasitology and the United States National Parasite Collection, 6 new species of Monoecocestus Beddard, 1914, are described, along with a redescription of Monoecocestus mackiewiczi Schmidt and Martin, 1978, based on the type specimens. The discussion includes commentary about uterine development, an important taxonomic character of the family, the vaginal dilation in immature segments (a character of potential taxonomic importance), and the implication of host usage to the evolutionary history and biogeography of species in this genus.
裸头绦虫在全球范围内均有分布,但南美洲啮齿动物体内已知的种类相对较少。通过对哈罗德·W·曼特寄生虫学实验室和美国国家寄生虫收藏馆的馆藏进行研究,本文描述了6种新的单殖裸头绦虫属(Monoecocestus Beddard,1914)物种,并基于模式标本对1978年施密特和马丁描述的马氏单殖裸头绦虫(Monoecocestus mackiewiczi)进行了重新描述。讨论内容包括有关子宫发育(该科一个重要的分类学特征)、未成熟节片中阴道扩张(一个可能具有分类学重要性的特征)的论述,以及宿主利用情况对该属物种进化史和生物地理学的影响。
