New data on the Hemiptera (Heteroptera) fauna from the Peter the Great Gulf islands, Sea of Japan

This paper reports the results of a follow-up research on heteropteran fauna from the Peter the Great Gulf islands, including Askold, Popov, Russky, De-Livron, Putyatin, Rikord, and Reineke, as well as adjacent coastal areas, including the Gamow Peninsula, Spaseniya Bay vicinity, and Cape Ostrovok Falshivyi. In total, 59 species were discovered for the first time, with two families added to the local fauna — Belostomatidae Leach, 1815, and Aradidae Btullé, 1836. Sepontiella aenea (Distant, 1883) (Pentatomidae) represents the first recorded occurrence of this species in Russia. Together with the previously reported species, a total of 113 species of bugs from 26 families were identified across the surveyed island territories. Previously reported invasive species, likely originating from the Korean Peninsula — Cletus schmidti Kiritshenko, 1916 (Coreidae), and Cantao ocellatus (Thunberg, 1784) (Scutelleridae) were reconfirmed.
