Abstract

Illustrated description of two species of free-living nematodes, Terschellingia coronata sp. nov. And Cyartonema minor sp. nov., found in mangrove thicket of Vietnam. T. coronata sp. nov. morphological similar to T. elegans Gagarin, Nguyen Vu Thanh 2003 and T. lutosa Gagarin, Nguyen Dinh Tu, 2014, but differs from both species by absence of labial and cephalic sensillae and shorter and thicker body. C. minor sp.nov. differs from near species C. parvulum Tchesunov, 1973 by shorter body, relatively shorter pharynx, longer spicules and absence of precloacal supplement.
