Notocotylus malhamensis n. sp. is described from the caecum of the bank vole (Myodes glareolus) and the field vole (Microtus agrestis) from Malham Tarn Nature Reserve in North Yorkshire, UK. In total, 581 specimens were collected from rodents trapped at a wetland site (Tarn Fen) between July 2010 and October 2011 with a prevalence of 66·7% and mean intensity of 94·6 in the bank vole and 50% prevalence and a mean intensity of 4·3 in the field vole. This species appears to be most closely related to other previously described Notocotylus species infecting rodents in Europe but differs principally by the metraterm to cirrus sac ratio (1:1·5-1:1·2) in combination with a densely spinulated cirrus, simple caeca and a greater number of ventral glands in the lateral rows (14-17). The use of molecular differentiation was of limited use in this study due to a paucity of relevant information in the DNA sequence databases. However, the complete ITS1-5.8S rDNA-ITS2 and partial 28S gene sequences have been generated to provide a definitive tool for identification of this species in future studies. As far as we know this is the first report of a notocotylid infection in M. glareolus in the UK.
新种 Notocotylus malhamensis 从英国北约克郡马尔汉姆塔恩自然保护区的盲肠中采集到的 bank vole(Myodes glareolus)和 field vole(Microtus agrestis)中描述。共从 2010 年 7 月至 2011 年 10 月在湿地(塔恩芬)捕获的啮齿动物中采集了 581 个标本,在 bank vole 中的流行率为 66.7%,平均强度为 94.6,在 field vole 中的流行率为 50%,平均强度为 4.3。该物种与其他先前描述的感染欧洲啮齿动物的 Notocotylus 物种最为密切相关,但主要区别在于 metraterm 到 cirrus sac 比率(1:1.5-1:1.2)与密集的刺状环、简单的盲肠和侧排中更多的腹腺(14-17)相结合。由于 DNA 序列数据库中相关信息有限,分子分化的使用在这项研究中受到限制。然而,已经生成了完整的 ITS1-5.8S rDNA-ITS2 和部分 28S 基因序列,为未来的研究提供了鉴定该物种的明确工具。据我们所知,这是英国首次报道 M. glareolus 感染 notocotylid 的情况。
