On the basis of morphological, physiological, distributional and biological evidence, it is concluded that the genera Steinernema and Heterorhabditis are widely divergent and similarities of life cycles can be attributed to convergence. Data is presented which indicates that Heterorhabditis evolved from a Pellioditis-like-ancestor in an arenicolous marine environment whereas Steinernema probably evolved from a '' proto-Rhabditonema '' ancestor in a terrestrial environment.
