Remarks.

Dorcadion crassipes is distributed in southeastern Kazakhstan, northwestern China and Kyrgyzstan. Three subspecies have been described to date: D. c. crassipes , D. c. glazunovi Suvorov, 1910 and D. c. validipes Jakovlev, 1906. The nominotypical form is endemic to SE Kazakhstan and is known to occur eastwards from about the Chu-Ili Mountains to the Dzungarian Alatau ( Danilevsky 1996b, 2018a). This is the most variable species of the Compsodorcadion group, which also includes Dorcadion ganglbaueri Jakovlev, 1898, Dorcadion cephalotes Jakovlev, 1889 and Dorcadion gebleri Kraatz, 1873. According to Toropov and Milko (2013), both adults and larvae are ecologically associated with the needle grass of the genus Achnatherum , especially with Achnatherum splendens (= Stipa splendens = Lasiagrostis splendens ). Additionally, Danilevsky (1996b) claims that all of the taxa of the former Compsodorcadion subgenus are related to the grasses of the genus Lasiagrostis .

Despite several hours of searching at the locality near Kegen, only two males were collected in a mountain steppe habitat sympatrically with Dorcadion arietinum arietinum and Dorcadion semenovi semenovi Ganglbauer, 1884. This seems to confirm the interesting observations of Danilevsky (1996b) that although two or three Dorcadion species often occur together in the same locality, they are never two species of the same subgenus. Similarly, in our study three species represented three different subgenera: Acutodorcadion Danilevsky, Kasatkin & Rubenyan, 2005, Cribridorcadion Pic, 1901 and Dorcadion s. str. Dalman, 1817. This new locality in the environs of Kegen is the southeasternmost known location of this species, which is situated more than 100 km from the nearest sites that are already known. The plot (Fig. 13D) was mainly covered with high tufts of grass.
