New Darwin wasps (Hymenoptera, Ichneumonidae, Tersilochinae, Tryphoninae) from the Eastern Palaearctic region

In this study, we describe two remarkable species, Ctenochira arkadyi Kasparyan, sp. nov. (Tryphoninae) from southern Siberia (Russia), and Probles arkadyi Khalaim, sp. nov. (Tersilochinae) from Japan. These two species are named in honour of our colleague and friend, an expert in Aculeata (Hymenoptera), Russian entomologist, Prof. Arkady Lelej, in honour of his 75 th birthday. The recently described European species, Ctenochira magnusi Haraldseide, 2018, is discovered from the Russian Far East; the male of C. magnusi is recorded and described for the first time.
