On the Knowledge of the Leaf-Beetle Fauna (Coleoptera, Chrysomelidae) of Siberia and the Russian Far East.

Two new species of the leaf-beetles, Aphthona ussuriensissp. n. and Tricholochmaea ussuriensissp. n., are described from Primorskii Territory of Russia. Seven species are recorded from Russia for the first time: Lema concinnipennis Baly, 1865; Phratora ryanggangensis Gruev, 1994; Dibolia potanini Wiese, 1889; D. zaitzevi Medvedev, 1980; Longitarsus hopeianus Chen, 1941; L. piceorufus Chen, 1939; Luperomorpha nigra Chen, 1933. A new finding of Longitarsus nipponensis Csiki, 1940 in Russia is reported. A new color form of Cryptocephalus luridipennis Suffrian, 1854 is described from the Sikhote-Alin Mountains. New identification keys to all the species of the genera Aphthona and Luperomorpha and to the species of Monolepta with a yellow pattern on black elytra from the Russian Far East are compiled. Photographs of the dorsal habitus of the adults and of the aedeagus are provided for all the aforementioned species and also for those included in the keys and plus Aphthona hammarstroemi Jacobson, 1901, Tricholochmaea semifulva Jacoby, 1885, and Pyrrhalta flavescens (Weise, 1887) closely related to the new species described herein. Photographs of the spermatheca of Monolepta hieroglyphica biarcuata Weise, 1889 and M. quadriguttata (Motschulsky, 1860) and of the male pygidium of M. quadriguttata (Motschulsky, 1860) with a deep transverse depression are also given for the first time; the latter character is newly reported to distinguish M. quadriguttata from all the Far Eastern congeners.
