Morphological variability of parthenogenetic Cephalenchus hexalineatus and amphimictic Filenchus misellus was studied in populations of single female progenies reared on birch seedlings in laboratory for four months. In the females of both species the measurements and the indices related to the anterior body part (stylet length, pharynx length, position of excretory pore and hemizonid, MB, EP%L) and to the genital area (V, V’) were the least variable morphological characteristics. Ovary length, body width, anal body with, tail length, and indices a and c’ showed the greatest variability. The taxonomy of both species is discussed.
