Abstract

The systematic position of Campydora which possesses many unique morphological features, especially in pharyngeal structure and stomatal armature, has long been a matter of uncertainty. Thorne (1939) remarked that the ?position of the Campydorinae' (containing only Campydora) was questionable. Jairajpuri (1983) reviewed the morphology of C. demonstrans, the sole species of Campydora, and concluded that the species warranted placement as the sole member of a monotypic suborder, Campydorina, in the order Dorylaimida. Other authors, notably Siddiqi (1983), place Campydorina in the order Enoplida. We conducted phylogenetic analyses, using 18s small subunit ribosomal DNA sequences generated from a number of taxa in the subclasses Enoplia and Dorylaimia, to evaluate these competing hypotheses. Although precise taxonomic placement of the genus Campydora, and the identity of its closest living relatives, is in need of further investigation, our analyses, under maximum parsimony, distance, and maximum likelihood criteria, unambiguously indicate that Campydora shares more recent common ancestry with genera such as Alaimus, Pontonema, Tripyla and Ironus (Enoplida) than with any members of Dorylaimida, Mononchida or Triplonchida.
