- Abstract
Summary: The second population of Pratylenchoides riparius , including females and males, is described and illustrated based upon morphological, morphometric and molecular data. The present population from Iran is characterised by some differences with the type population of the species from Hungary in stylet length (24-26 vs 21-22 μ m), slightly longer body (1002-1230 vs 830-960 μ m), pharynx (202-211 vs 182-190 μ m) and tail (64-85 vs 48-57 μ m), areolated outer bands of the lateral field (vs non-areolated), widening of the lateral field near tail terminus (vs lateral incisures connecting each other) and presence of males (vs absent). The taxonomic status of the species with regarding the data from the type and presently recovered population, as well as the closely similar species is discussed. The newly recovered population was studied based upon its molecular phylogenetic charactes using the D2-D3 of 28S rRNA and the partial 18S rRNA gene sequences and the results revealed that it forms a clade with P. magnicauda in 28S, but occupies a distant placement from it in 18S phylogeny.
