A New Finding of the Non-Native Copepod Sinodiaptomus sarsi (Copepoda, Calanoida, Diaptomidae) in Ukraine

Abstract

Sinodiaptomus sarsi is found for the second time in Ukraine, in the three artificial lakes of the one of capital Kyiv city`s park, Nyvky, after its first record in the Carpathian Mountain region near Slovakian border in 2016 by Dr. Mykitchak. Our morphological study showed the similarity between the specimens of S. sarsi found in Kyiv with existing illustrations and descriptions of the Asian population of this species. The most likely route of penetration is human intentional release. Some diagnostic details are discussed and short redescription of species is presented in the paper.
