Two New Nematode Species of the Genus Paramononchus (Nematoda, Mononchida) from Lake Baikal (Russia)

This paper describes and illustrates two new nematode species of the genus Paramononchus Mulvey, 1978 founds in Lake Baikal. Paramononhus obesus sp. n. is morphologically similar to P. kirjanovae (Tsalolikhin, 1975) and P. orientalis (Gagarin and Naumova, 2012), but differs from both species by the thicker body, less slender tail, longer spicules and more supplements. Paramononchus vulgaris sp. n. resembles P. absconditus (Tsalolikhin, 1974) and P. kirjanovae, but have the thicker body, longer spicules and more supplements.
