摘要：

Genera that show a transitional series are difficult to define: the series discussed is Rotylenchus - Scutellonema - Peltamigratus - Aorolaimus - Hoplolaimus. Two hypotheses are presented. First the evolutionary development of this series is associated with the theory of continental drift. Second the morphology of tylenchs is almost unchanged during the last 200-300 million years, explaining the large genetic variation found within some species. © 1990 BRILL.
