During the study of coastal harpacticoid communities of Lake Baikal, representatives of two new species were discovered: Moraria (Baikalomoraria) okunevae sp. n. and Moraria (Baikalomoraria) ornofurcata sp. n. Morphologically, both new species are similar to Moraria (Baikalomoraria) spinulosa Borutzky et Okuneva 1972, but differ well in the structure of the caudal rami. The morphology of these species was studied using scanning electron microscopy. An illustrated description is provided, and variability characterized.
