The information, techniques and strategies used by nematode taxonomists have improved in major ways over the last 15 years. New methods of specimen preparation, new microscopic procedures, and new morphological and molecular characters have improved the quality of nematode descriptions. Testing taxon demarcations and morphological character reliability with one or more molecular markers used to construct phylogenetic trees has produced new frameworks that affect practical identification. Recent molecular sequence comparisons of morphologically similar species within Pratylenchidae and Telotylenchidae have revealed that some species are very different phylogenetically.
