           Seinura Fuchs, 1931

   
   
The genus Seinura, described by Fuchs (1931), was synonymized with Pathoaphelenchus Cobb by Steiner (1931) and later with Aphelenchoides Fischer by T. Goodey (1933).  J.B. Goodey (1960) reestablished Seinura as a valid genus in the Aphelenchoididae and assigned 15 species to it (Hechler, 1963).

Feed as predators: Use stylet to penetrate prey and withdraw body contents (Bilgrami, 2008).
