- Abstract
Trichodorus variabilis, recovered from three separate locations in natural forests of northern Iran, was studied using morphological, morphometric and molecular data. Variation in position of the ventromedian cervical papillae (CP1 and CP2) with respect to the onchiostyle base in the resting position, and spicule characters (having or lacking striation in distal blade region and bristles in proximal blade region) were observed. Variation was also observed in the nature of the pharyngo-intestinal junction (offset to slight overlapping). The secretory-excretory pore of females also showed slight variation in placement. Molecular phylogenetic studies, using partial 28S rDNA D2-D3 sequences of three studied populations and one sequenced isolate of the species from Greece, revealed T. variabilis has variation in the sequences of this genomic fragment. The similarity percent of four sequences ranged from 96.7 to 99.7%. The species was found for the first time outside of Greece, the country from which it was originally described. A newly recovered population of T. persicus, originally described from Iran, was also included in the molecular phylogenetic analyses.
