摘要

在贝加尔湖北部盆地 Chivyrkuy 海湾沿岸 11 米深处采集到广泛分布的微蝽种 Microstomum lineare（Müller，1773 年）的标本。这是贝加尔湖和东西伯利亚对该物种的首次可靠记录，扩大了M. lineare的分布范围，并使贝加尔湖微囊藻的种类增至两个。此外，在贝加尔湖发现 M. lineare 是克服贝加尔湖与古北区动物群之间障碍的又一例证。

First record of Microstomum lineare (Plathelminthes: Dolichomicrostomida: Microstomidae) from Lake Baikal

Specimens of the widespread microturbellarian species Microstomum lineare (Müller, 1773) were collected in the coastal zone of Chivyrkuy Bay in the northern basin of Lake Baikal at a depth of 11 m. All taxonomically significant characters of the collected specimens are fully consistent with the diagnosis of this species. This is the first reliable record of the species from Lake Baikal and from Eastern Siberia, expanding the data on the range of M. lineare and increasing the list of Baikal microstomids to two species. And furthermore, the finding of M. lineare in the lake is another example of overcoming the barrier between the Baikal and Palaearctic faunas.

期刊介绍： Zoosystematica Rossica is an international journal for publication of papers on any aspects of systematic zoology, in all groups of animals, both extant and fossil, from all over the World. The journal is published in English and focuses on the descriptions of new taxa, revisions and reviews, nomenclature, theories and methods of taxonomy and phylogeny, interesting new faunal records, catalogues and checklists, identification keys, phylogenetic relationships and zoogeography. Faunistic articles are published in a limited way and only if they contain new records for large geographical regions and are important for zoogeography or taxonomy.
