Remarks. Description not included in above reference. Pratylenchus mediterraneus differs from the closely related species P. thornei by having a shorter stylet and the presence of males. These differences are supported by molecular analysis of the D3 expansion of the 26S ribosomal genes, which indicated that P. mediterraneus and P. thornei sequences have differences in some crucial nucleotide positions, strongly indicating that P. mediterraneus should be maintained as a valid species (De Luca et al. 2004).
