Sequence data were obtained for the full length of the ribosomal DNA (rDNA) 18S gene of specimens from three populations of Paratrichodorus christiei from the USA and four populations of P. minor from Brazil and Portugal. Alignment of the sequences and their application in a phylogenetic analysis revealed that the populations of P.christiei and P.minor formed a single cluster that differentiated from a second cluster comprising P.anemones and P.pachydermus. Previously, P.christiei had been proposed as a junior synonym of P.minor, but this synonymy had not been universally accepted, with many reports, particularly from the USA, continuing to refer to P. christiei. The results obtained here with the sequences of the rDNA 18S gene from the various populations confirm the validity of the synonymy of P.christiei with P.minor.
