Abstract

Illustrated description of free-living nematodes, Daptonema securum sp. nov., found in ground of artificial reservoirs in Vietnam. D. securum sp. nov. differs from three relatives of length of body to species: D. communis Gagarin & Nguyen Vu Thanh, 2014, D. biggi (Gerlach, 1965), D. rectungulatum Pastor de Ward, 1985 by presence of thin annulated cuticle, very long of inner labial setae and another structure of gubernaculum. Morphometric data of males of 17 new species, described from water bodies in Vietnam are given.
