The occurrence of Kishidaia conspicua (L. Koch 1866) in the Russian Far East is confirmed. This species name is shown to be a senior synonym of K. xinping Song, Zhu & Zhang 2004 syn. n. Two new combinations are established: Yunohamella serpatusa (Guan & Zhu 1993) comb. n. and Yunohamella palmgreni (Marusik & Tsellarius 1986) comb. n., both ex Theridion. Yunohamella serpatusa is shown to be a senior synonym of Theridion tigrae Esyunin & Efimik 1996 syn. n. The record of Yunohamella serpatusa from the Botchinski Reserve (Khabarovsk Province) lies at the easternmost limit of its range. Spiders from the Botchinski Reserve are reported for the first time.
