, 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.

The night migration complex in the bottom zone of the shallow-water slope on the east coast of southern Lake Baikal near the village of Kluevka was investigated. According to the observations, it was established that the pelagic fish of the suborder Cottoidei and the pelagic amphipodMacrohectopus branickiican sporadically participate in the migration complex. The mass presence of benthic amphipods was highest in the first minute of observations, with more than 250 individuals/freeze-frame, and then stabilized at 43-65 individuals/freeze-frame. The Juday net-collected amphipods comprised only one typically benthic species,Micruropus wohlii platycercus, which is known to be a nocturnal migrant. For the first time, the typically pelagic speciesM. branickii, was observed in the migratory complex over shallow coastal shoal, which species, according to all previous studies, was considered to inhabit only greater depths and to avoid areas with depths of less than 100 m, such as shallow-water slope bottom zones.

Construction of the Baikal amphipod taxonomy amphipods clearly highlights the situation when the editors for a particular taxonomic group subjectively favor certain nomenclature acts and regard the alternative ones unaccepted. This is their right as the editors. However, we firmly believe that WoRMS is just a database and the exclusive use of names accepted there SHOULD NOT be mandatory in scientific publications, if the authors are capable to argue for validity of alternative nomenclature.
