, 110 genera and 581 species and subspecies are reported. Species that constitute the autochthonous complex of Lake Baikal comprise 61% of the fauna (276 species, and 78 subspecies). The current taxonomic and the nomenclatural problems of amphipods from the Baikalian and Caspian groups are discussed. A separate list of alien species (or invaders) for continental waters of Russia is provided. РЕЗЮМЕ. Приведен таксономический контрольный список видов амфипод, зарегистрированных в континентальных водоемах, водотоках и подземных водах Российской Федерации (по данным на конец 2013 г.). Виды подразделены на 11 эколого-биогеографических групп: голарктические, западно-палеарктические, балтийские эстуарные, сибирско-тихоокеанского региона (восточно-палеарктические), амфипацифические, кавказские, центрально-азиатские, байкальские, эмигранты из Байкала, виды понто-каспийского происхождения, эмигранты из Северного Ледовитого океана. На дан-ный момент отмечено 26 семейств, 110 родов и 581 вид и подвид амфипод. На виды, составляющие автохтонный комплекс озера Байкал, приходится 61% состава фауны (276 видов и 78 подвидов). Даны пояснения, касающиеся современных проблем таксономии и номенклатуры байкальских и каспийских амфипод. Отдельно приведен список чужеродных видов, или видов-вселенцев в континентальные водоемы регионов России вне их первоначального ареала.

(Crustacea, Amphipoda, Crangonyctidae), first report of a subterranean amphipod from the catacombs of Odessa and its zoogeographic importance. Subterranean Biology 15: 11-27. Abstract A new species from the catacombs of Odessa (South Ukraine), Synurella odessana sp. n. is described and its taxonomic affinity with congeners are discussed. This is the first record of the subterranean amphipod crustacean of the genus Synurella from an artificial biotope. The new species has numerous plesiomorphic features states allowing a more detailed evaluation of the taxonomy of the genus Synurella. The most remarkable feature of this new species is the presence of a "synurellid type" gnathopod 1 and a "crangonyctid type" gnathopod 2. Herein, we propose three groups in the genus Synurella distributed within the Volga-Black Sea basin: ambulans-group (epigean inhabitants of coastal lowlands, stygophiles), dershavini-group (hypogean or spring inhabitants of karstic regions, preadapted stygobionts), wachuschtii-group (minute inhabitants of interstitial waters, stygobionts). The dershavini-group occupies isolated taxonomic position among the synurellids. We suggest that the modern distribution of dershavini-group reflects the formation of ancient river basins in the region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
