摘要

This paper describes two new species of the genus Gammarus Fabricius from the freshwaters of Central Asia: G. montaniformis sp. nov. (Kazakhstan, Dzungarian Alatau, Borohudzyr River) and G. alius sp. nov. (Kyrgyzstan, Chatyr-Kul Lake). The morphologyof the mouth parts of the new species G. alius is characterised by a peculiar upper lip with "hooks" on its epistome that is discussed. The affinity of the new species for their congeners is discussed, emphasizing morphological and biogeographical relationships.
