Abstract

The paper provides illustrated descriptions of two new nematode species of the order Enoplida Filipjev, 1929 found in the water bodies of Vietnam. Viscosia orientalis sp. nov. is morphologically similar to V. timmi Gagarin, Nguyen Thi Thu, 2008 and V. longicaudatoides Nguyen Vu Thanh, Gagarin, 2013, however, this species has a shorter and thicker body and longer spicules. Halalaimus borealis sp. nov. is similar to H. luticolus Timm, 1961 and H. longipharynx Gagarin, Nguyen Vu Thanh, 2018, and differs from those species in having a longer body, its vulva location, which is closer to the anterior body end, and a longer and slenderer tail. The author provides the dichotomic key for the identification of valid species males of the genus’ Halalaimus 4th species group.
