Abstract
Systematization of data on Cyclopoida from individual regions is one of the important stages in research into the world fauna of the order. This work aims to compile an up-to-date list of Cyclopoida species of Kazakhstan based on a critical analysis and systematization of literature and our data. A generalization of data showed that the water bodies of Kazakhstan are inhabited by 58 species and 1 subspecies of Cyclopoida from 3 families and 19 genera. The largest number of species include the genera Diacyclops (7), Eucyclops (6), Cyclops (4), and Thermocyclops (6). Cyclopoida species richness distribution across zoogeographical provinces of Kazakhstan was relatively uniform.
