Interpretive Summary:

Technical Abstract: The future of nematode taxonomy will be characterized by rapid accumulation of new and revised taxa examined in light of a refined understanding of phenotypic plasticity and cryptic speciation, multiple molecular markers and appropriate phylogenetic analyses. The inevitable result will be improved taxonomic specificity and integrity in an era of large international collaborations. One of the limiting factors will be support for collections housing type specimens. Species diagnoses are effectively hypotheses without clear type associations. Unfortunately, the phylogenetic coverage of nematode molecular sequences that relate to recent live and especially type specimens is still very sparse. However, as molecular genetic resources become more accessible and informative, we will improve the taxonomic resolution needed for rapid diagnosis of emerging pests and critical ecosystem indicator species.
