Diagnosis. The new species differs from its congeners in the region (i.e. T. gromovi Marusik, 2011 , T. susianus Zamani & Marusik, 2021 and T. Jacksoni Marusik & Guseinov, 2003 ) by the lack of distinct epigynal fovea ( Fo) ( vs. present in other species), and by the parallel epigynal sclerotization ( vs. triangular or absent, cf.
