description, intraspeci? c variability, morphology, new diagnosis, taxonomy
The morphology and intraspecific variability of the nematode species Mesodorylaimus bastiani (Bütschli, 1873) Andrássy, 1959 are described. In addition to type specimens, material has been examined from ten localities in south-eastern Spain and three localities in Belgium and The Netherlands. Detailed descriptions, tables of measurements and ratios, and illustrations are included. A revised diagnosis of the species is presented, being characterised by its medium sized body (L = 1.30-1.80 mm), lip region diam. 11-14 mm and continuous or offset by a weak depression, odontostyle 13.5-16.5 mm, V = 48-56, pars refringens vaginae with two quite close sclerotisations, female tail elongated and consisting of a conical part followed by a slender portion which tapers to an acute or finely rounded tip (75-100 mm, c = 14-23, c¢ = 3.0-4.0), spicules 39-52 mm and eight to 11 spaced ventromedian supplements. Previous records of the species are critically discussed.
