** Melanopa grandis Roewer, 1910

MATERIAL. Khingansky Reserve , 7 km SE of Uril village, Dyrovatka River Valley, 06.VIII.2022, 3♂ .

DISTRIBUTION. Russian Far East (Amurskaya Oblast, Primorsky Krai), China, Korea, Japan.

An annotated list of spiders (65 species from 48 genera in 17 families) and harvestmen (five species from 5 genera in two families) of the Khingansky Reserve and adjacent territories of Arkhara District is given. Two spider species ( Cyclosa ginnaga and Diaea gyoja ) are new for the fauna of Russia. Twenty six species of spiders and four species of harvestmen are new for the fauna of the Amurskaya Oblast. Thirty seven species of spiders and all harvestmen were recorded from Khingansky Reserve for the first time.

Based on the present study and published data, 117 spider species are currently known from the Khingansky Reserve. Due to the wide distribution of forestless habitats with diverse floristic composition herbage in this region, high species diversity is represented by the families of jumping and crab spiders, as well as representatives of several web-building spider families, mainly of small and medium sizes. The analysis of published data ( Azheganova & Stenchenko, 1977; Marusik, 1989; Kurenshchikov, 1994) in combination with our own data indicates a high regional diversity of species and genera in the families Tetragnathidae and Araneidae .
