Two new Epsilonema-species are described: E. parvospina sp.nov., characterized by the ornamentation of the body cuticle and the single ventral row of 3 to 5 copulatory thorns in male and E. longispicula sp.nov., characterized by the ornamentation of the cuticular body rings, long spicus and two single ventral rows of copulatory thorns in male. A new genus Triepsilonema with a new species T. tripapillata gen. n., sp.n. is described. Triepsilonema is mainly characterized by the six rows of ambulatory setae and the separate outlet for each of the three caudal glands.
