Material examined. 1 male ( FSCB), Russia, Primorsky Krai, Anuchinsky District , about 35 km NW of Arseniev, VIII.1986 , leg. V.D. Bakurov ; 1 male ( FSCB), Russia, Primorsky Krai, environs of Vladivostok, middle course of the Malaya Sedanka River , river bank, 9. V.2010; 1 male, 1 female ( FSCB), Russia, Vladivostok, Botanical garden, 22. V.–1. VI.2010; 1 male ( FSCB), Russia, Vladivostok, Botanical garden, 13–20. VI.2010, all leg. S.A. Shabalin; 1 male, 1 juv. ( FSCB), Russia, Vladivostok , Botanical garden, broadleaved forest, litter, 25.X.2019, leg. E. V. Mikhaljova, A.I. Konyukhov .

Distribution. Russia: Far East (southern and central parts of Primorsky Krai).

Remarks. The study of the gonopods of the males from the collection of FSCB using a scanning electron microscope has revealed some additional structural details ( Figs 15–16 ): posterior face of colpocoxites covered with small and relatively large papillae; subbasal mesal outgrowths of the posterior angiocoxal process papillate; telopodites of anterior gonopods mesally covered with tiny spinules. In addition, the examination of the male legs 11 has revealed similarity to those of D. provecta . Thus, coxae 11 of D. yakovlevka are supplied with a ventral cavity and a lateral papillate protuberances as well as a median conical processes with the small aperture of the coxal gland apically. This character was omitted in the original description of D. yakovlevka (see Shear 1990). Therefore, it is necessary to add it to the description of this species.
