摘要: A study of the structure limbs Bosminopsis deitersi Richard, 1895 was performed. Thestructure is similar in populations from differentregions. According to Meissner (1903), differ those Bosminastrongly enough separate aspecial family. However, our observations indicatethat Bosmina andBosminopsis similar, and conform thegeneral plan Bosminid limbs. The first limb isstrongly simplified, males isunique among anomopods. Limbs III–V are lessoligomerized than I–II, organizedaccording chydorid (and macrothricid) type. Thedegree oligomerization different twogenera. Comparative information on structurein one genus may contribute reconstruction ofthe evolution a corresponding othergenus. uniformity within eachgenus, their similarity between both genera isthought be reflection monotonous lifeconditions open water.
