Abstract
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.
