Sükhbaatar : 40 km SE of Baruun-Urt [Баруун-Урт] [ca. 46.378 , 113.572 ], 14.07.1971 , 1 ♂ ( Namhaidorzh 1974 : as Oberea sp. ) . Remarks. According to Lin & Ge (2017) , Oberea donceeli Pic, 1907 is known exclusively from China ( Beijing and Tianjin ), while in Mongolia , Russia , China ( Hebei , Shanxi , Inner Mongolia , Shaanxi , Gansu , Ningxia ), and Turkey O . ressli is distributed. However, such a disjunctive range seems quite unusual and further study should be conducted to clarify wheather the Turkish and east-Palaearctic specimens belong to the same taxon. In Danilevsky (2020) , the distribution for O . ressli has not been changed (currently only Turkey ) despite the mention of Lin & Ge’s (2017) paper in the remarks. Similarly, in Danilevsky (2021a) , O . donceeli , not O . ressli , is recorded for Mongolia . According to Lin & Ge (2017) , O . ressli differs from O . donceeli by its antennae and elytra being black, and the prothorax with a black longitudinal stripe on each side. The Mongolian specimen from Dornod aimag (Choibalsan), collected on June 23, 1976 by V. Namkhaydorzh, which is presented in the Internet (zin.ru), clearly resembles the former species. Therefore, we consider Namhaidorzh’s (1974) record of Oberea sp. from Sükhbaatar aimag as O . ressli . Species from Amaurostoma group are ecologically associated with Euphorbia L. ( Euphorbiaceae ). According to the data on the biology presented by Cherepanov (1991b) for O . donceeli , and therefore consequently for O . ressli , this species inhabits montane-steppe regions and the adults occur from mid-May to mid-July.
