NEW DATA ON THE FAUNA OF LEAF-BEETLES (COLEOPTERA, CHRYSOMELIDAE) FROM THE SOUTH OF THE RUSSIAN FAR EAST

Abstract

Four species are recorded from Russia for the first time: Altica cirsicola Ohno 1960, Neocrepidodera recticollis (Jacoby 1885), Sphaeroderma tarsatum Baly 1874 and Cassida koreana Borowiec Cho 2011. A new colour form of Cryptocephalus flavoscutellaris Medvedev 1973 is described from Sakhalin. The variability of body coloration in Cryptocephalus nigrofasciatus Jacoby 1885 is discussed. The following synonymy is confirmed: Cryptocephalus nigrofasciatus Jacoby 1885 = Cryptocephalus turpis Chen 1942. Two taxa, Cryptocephalus sagamensis Tomov 1982 from South Korea and C. nigrofasciatus are probably conspecific. A new record of Altica caerulescens (Baly 1874) from Russia is provided and its differences from Altica viridicyanea (Baly 1874) are given. New data on the rare Aphthona ussuriensis Romantsov 2021 and Monolepta pallidula (Baly 1874) are presented. The status of three similar species of the genus Sphaeroderma Stephens 1831 (S. fuscicorne Baly 1864, S. akebiae Ohno 1964 and S. unicolor Kimoto 1965) is discussed. А new identification key to all species of this genus from the Russian Far East is compiled. Characters for distinguishing Cassida koreana Borowiec Cho 2011 from Cassida vespertina Boheman 1862 are given. Dorsal habitus photographs of adults and their genitalia are provided for all aforementioned species and their close allies.
