East Kazakhstan Region: 12 km S of Zaysan [ Zaisan ] ( 47°21'N , 84°51'E ), 965 m a.s.l., 7 V 2017, 1♂, 1♀, leg. RP; 1♂, 1♀, leg. KL. Remarks. This species is distributed in northeastern Kazakhstan and the Xinjiang region in China. The species includes two subspecies: P. r. ribbei (Kraatz, 1878) and P. r. bobrovi , whose populations are separated by the Manrak and Saur Mountain ranges ( Toropov and Milko 2013 , Danilevsky 2018a ). Politodorcadion ribbei bobrovi is endemic to Kazakhstan and occurs exclusively on the northern slopes of these mountains in the border zone with China. It inhabits clayey and stony semi-deserts in piedmont valleys with sparse grass vegetation. The larvae feed on various species of Poaceae . The adults are active from the end of April to the end of May ( Toropov and Milko 2013 ).
