Twenty species of Orthoptera in 19 genera and four families are recorded from the Komsomolsky Nature Reserve for the first time and only four species in two families are found in the wildlife preserve «Udyl». The species riches of Orthoptera recorded from the natural reserves in the Amur Region of the Russian Far East are compared. Number of species in Komsomolsky and Bastak reserves is almost the same (15–20 species), while 51 species of Orthoptera are known from Khingansky Reserve.

New fossil taxa of Embolemidae and Dryinidae (Hymenoptera: Chrysidoidea) are described. For Embolemidae, Embolemopsis baissensis n. gen. n. sp. and Baissobius minutus n. sp., are described from Central Siberia, West Transbaikalia, left bank of Vitim River (facing downstream), Baissa, lake deposits from earlier Early Cretaceous (Neocomian stage) (130–140 mybp). For Dryinidae, Anteonopsis antiquus n. gen. n. sp., Bocchus ? cenomanianus n. sp. and Gonatopus ? cretacicus n. sp., are described from Siberia, Magadan Region, Obeschchayushchiyi, tuffaceous deposits from Upper Cretaceous (Cenomanian) (90–95 mybp); Deinodryinus ? aptianus n. sp., is described from Central Mongolia, Bayanhongor Aimag, 5–8 Km N Bon Tsagan Nuur Lake, from impressed in lake deposits of the Khurilt rock unit probably of Aptian (Early Cretaceous) (100–115 mybp). In addition, an unidentified fossil belonging to Deinodryinus ? or Dryinus ? is recorded from Russian Far East, Maritime Province, Velikaya Kema (later Earlier or early Middle Miocene) (about 30 mybp). The known species of Baissobius Rasnitsyn are reviewed and a key is presented.
