Two new species of free-living nematodes of the genus Laimydorus (L. gigas sp. nov. and L. tenuis sp. nov.), found in the sediments of small freshwater bodies in Vietnam, are described and illustrated. Laimydorus gigas sp. nov. is similar to L. distinctus Dey, Baqri, 1986 and L. elephas Andrassy, 1988. From the former species it differs in the longer tail in females, the shorter spicules and greater number of supplements in males. From L. elephas it differs in the thinner cuticle, thinner body, comparatively longer odontostyle and comparatively longer prerectum in females. Laimydorus tenuis sp. nov. is similar to L. merogaster (Steiner, 1916) and L. pinguis Andrassy, 1988. From the former species it differs in the thinner cuticle, thinner body, shorter odontostyle, shorter spicules and smaller number of supplements in males. From L. pinguis it differs in the thinner body, shorter tail in females, another position of vulva and comparatively longer prerectum in females.
