New data on the distribution, biology and ecology of the longhorn beetles from the area of South and East Kazakhstan (Coleoptera, Cerambycidae)

New data on the distribution, biology and ecology of the longhorn beetles occurring in southern and eastern regions of Kazakhstan are presented together with a list of 78 species that were collected during two entomological expeditions conducted in May and June 2017. New localities of some rare taxa endemic to this region of Asia, such as Psilotarsus brachypterus brachypterus (Gebler, 1830), Stenocorus minutus (Gebler, 1841) and Dorcadion crassipes crassipes Ballion, 1878 are given. Exocentrus stierlini Ganglbauer, 1883 is recorded from Kazakhstan for the first time. Moreover, the occurrence of three species: Amarysius duplicatus Tsherepanov, 1980, Rhopaloscelis unifasciatus Blessig, 1873 and Saperda alberti Plavilstshikov, 1916, which were recently found in the country, is also confirmed. Furthermore, high-quality photographs of several unique taxa, i.e. Psilotarsus brachypterus pubiventris (Semenov, 1900), Xylotrechus adspersus (Gebler, 1830), X. alakolensis Karpiński & Szczepański, 2018, Anoplistes galusoi (Kostin, 1974), A. jacobsoni Baeckmann, 1904 and Oberea kostini Danilevsky, 1988 along with images of their habitats and feeding galleries are also presented. New localities of species considered serious pests or invasive, such as Turanium scabrum (Kraatz, 1882) and Trichoferus campestris (Faldermann, 1835), respectively, are also given. A new synonymy is proposed: Cerambyx scalaris Linnaeus, 1758 = Cerambyx hieroglyphicus Pallas, 1773, syn. n
