An annotated list of 42 species in 26 genera and four families of Orthoptera recorded from Beringia (Northeast Yakutia, Chukotka, Magadan region, and Kamchatka in Russia, Alaska in USA, Yukon and the Northwestern Territories in Canada) is given. The distribution of species is clarified. The exchange of orthopteran faunas between Asia and America by the Bering Land Bridge in Pleistocene was strongly limited. The only three species, Tetrix subulata (Linnaeus, 1761), Melanoplus frigidus (Boheman, 1846), and Stethophyma grossum (Linnaeus, 1758), are recorded from both Asian and American parts. The orthopteran fauna of Beringia is not original. Majority of Beringian species are widespread throughout either Asia or North America. There are only four endemic grasshoppers, namely two Asian subspesies, Melanoplus frigidus kamtchatkae (Sjosted, 1935) and Aeropedellus variegatus gelidus Mistshenko, 1951, and two American species, A. arcticus Hebard, 1935 and Bruneria yukonensis Vickery, 1969. Composition of the regional faunas is briefly discussed. The monotypic genus Bohemanella Ramme, 1951 is again considered as a synonym of Melanoplus Stål, 1873, where a type species of the former genus, Melanoplus frigidus (Boheman, 1846) comb. resurr., forming its own species group.
给出了 42 种 26 属 4 科直翅目昆虫在白令海峡地区（俄罗斯东北部雅库特、楚科奇、马加丹地区和堪察加半岛、美国阿拉斯加、加拿大育空地区和西北地区）的记录。阐明了物种的分布。在更新世，通过白令陆桥进行的亚洲和美洲直翅目动物区系的交流受到强烈限制。只有三种物种，即 Tetrix subulata（Linnaeus，1761）、Melanoplus frigidus（Boheman，1846）和 Stethophyma grossum（Linnaeus，1758），同时存在于亚洲和美洲部分地区。白令海峡地区的直翅目动物区系不是原始的。大多数白令海峡地区的物种广泛分布于亚洲或北美洲。只有四个特有蝗虫，即两个亚洲亚种，Melanoplus frigidus kamtchatkae（Sjosted，1935）和 Aeropedellus variegatus gelidus Mistshenko，1951，以及两个美洲物种，A. arcticus Hebard，1935 和 Bruneria yukonensis Vickery，1969。简要讨论了区域动物区系的组成。单型属 Bohemanella Ramme，1951 再次被认为是 Melanoplus Stål，1873 的同义词，其中前者的模式种，Melanoplus frigidus（Boheman，1846）comb。resurr.，形成其自己的物种群。
