Two erigonine genera from East Siberia are synonymized: Uusitaloia Marusik, Koponen & Danilov, 2001, syn. nov. = Dactylopisthoides Eskov, 1990. Two new combinations are established: Dactylopisthoides transbaicalicus (Marusik, Koponen & Danilov, 2001), comb. nov. and Dactylopisthoides wrangelianus (Marusik & Koponen, 2009), comb. nov. both ex. Uusitaloia. The epigyne of D. wrangelianus is illustrated for the first time. A new, updated diagnosis of Dactylopisthoides is proposed. The copulatory organs of both sexes of D. hyperboreus and D. wrangelianus are illustrated by SEM images.
