ABSTRACT. A new linyphiid species of the genus Trichoncoides is described from a clayey semi-desert in the environs of both Dzhanybek, western Kazakhstan and Lake Elton, Volgograd Area, southern Russia. The new species is similar to T. piscator (Simon, 1884), but differs well by the peculiar shape of the palpal tibia, of the anterior radical process in the male, as well as by the details of epigyne and vulva structure in the female.
