Abstract

The Gonioctena nivosa species-group of the genus Gonioctena Chevrolat, 1836 is defined and reviewed. It contains six species including two new to science: G. gracilicornis (Kraatz, 1879), G. nivosa (Suffrian, 1851), G. norvegica (Strand, 1936), G. springlovae (Bechyně, 1948), G. amurensis Cho & Borowiec, sp. n. and G. jani Cho & Borowiec, sp. n. Six new synonyms are proposed: G. nivosa (= G. arctica alberta Brown, 1952, syn. n., Phytodecta linnaeana bergrothi Jacobson, 1901, syn. n., P. linnaeanus var. mutatus Achard, 1924, syn. n., P. linnaeanus var. simplex Achard, 1924, syn. n. and P. nivosa var. cedehensis Ronchetti, 1922, syn. n.) and G. norvegica (= G. janovskii Medvedev, 1976, syn. n.). Phytodecta flavicornis var. limbatipennis Achard, 1924 and P. nivosa var. bicolor Heyden, 1883 are removed from synonymy with G. nivosa (Suffrian, 1851) and are synonymized with G. flavicornis (Suffrian, 1851). Distribution maps, a key to species, color variation, geographic variation of male genitalia and host plants are provided. Ovoviviparity is newly recorded in G. gracilicornis and G. nivosa. Lectotypes are designated for G. affinis, G. arctica, G. linnaeana bergrothi and G. nivosa.
