摘要

对贝加尔湖特有物种Canthocamptus（Baicalocamptus）longifuccatus Borutzky，1947（Harpacticoida：Canthocamptidae）进行了重新描述。所示的雌性和雄性形态的重新描述由基于线粒体COI标记序列的遗传条形码补充。Canthocamptus（B.）longifurcatus在形态上与亚属的另一个代表C.（B.）verestschagini（Borutzky，1931）非常相似，但可以通过雌性毛皮的电枢和雌性和雄性最后一对游泳腿的结构与后者很好地区分开来。对所获得的COI序列的分析及其与其他竖琴类物种的比较证实，C.（B.）longifurcatus属于Westwood Canthocamptus属，1836年：在所研究的贝加尔湖物种和欧洲（瑞士日内瓦湖）的C.staphylinus Jurine，1820之间观察到最小的遗传差异（平均29.5%）。

Integrative redescription of Canthocamptus (Baicalocamptus) longifurcatus (Harpacticoida: Canthocamptidae), an endemic species from Lake Baikal

A redescription of the Lake Baikal endemic species, Canthocamptus (Baicalocamptus) longifurcatus Borutzky, 1947 (Harpacticoida: Canthocamptidae), is provided. The illustrated redescription of morphology of the female and male is supplemented by a genetic barcoding based on sequences of the mitochondrial COI marker. Canthocamptus (B.) longifurcatus is morphologically very similar to another representative of the subgenus, C. (B.) verestschagini (Borutzky, 1931), but can be well distinguished from the latter by the armature of the female furca and the structure of the last pair of swimming legs in the female and male. An analysis of the obtained COI sequences and their comparison with those of other harpacticoid species confirmed that C. (B.) longifurcatus belongs to the genus Canthocamptus Westwood, 1836: the smallest genetic differences (on average, 29.5%) were observed between the studied Baikal species and C. staphylinus Jurine, 1820 from Europe (Lake Geneva, Switzerland).

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.
