Abstract
Analysis of variance has been applied as a new tool for precise substantiation of taxometric differences between Eustrongylides spinispiculum n. sp. and close species, as indicated by the polythetic divisive classificatory system. A revised key to the species of genus Eustrongylides Jagerskiod (1909) has been presented.
