title: [New species of ectoparasitic nematode of the genus Trichodorus from the coniferous forests of the Far East].
abstract: The diagnosis and figure are given of the new species of nematodes, Trichodorus yokooi sp. n., isolated from the risosphere of Abies nephrolepis and Picea ajanensis in the Maritime Territory. The new species is close to three japanese species described by Yokoo (1964, 1966) but differs from them in the spear size, the location of ventromedial papilles, excretory pore and suplementary organs, and in the structure of vagina and ovaries.
