Kabak, I. I. & Liang, H. - B., 2021, An annotated list of the genus Chlaenius Bonelli, 1810 (Coleoptera: Carabidae) of Xinjiang Uygur Autonomous Region of China, Far Eastern Entomologist 429, pp. 12-28 : 20

Chlaenius (Chlaeniellus) nigricornis (Fabricius, 1787)

MATERIAL. There are no specimens from Xinjiang examined by authors.

NOTES. The aedeagus shape of this species is rather variable in populations from different parts of its vast area. The intraspecific structure of Ch. nigricornis needs to be clarified.

DISTRIBUTION. It is Transpalaearctic species, distributed from Western Europe and

Northern Africa eastwards to Transbaicalia and Yakutia (Kryzhanovskij et al., 1995;

Kirschenhofer, 2017). In Middle Asia, Ch. nigricornis is recorded only from Kazakhstan. In this country, the species is known from the western, central, eastern and south-eastern parts,

including some localities neighboring to the Xinjiang territory: Lake Markakol in Southern

Altai, Tentek, Oisaz, and Kesken-Terek rivers in the Dzhungarian Alatau Mt. Range , as well as in the Ili, Charyn and Bayankol valleys. Rerecord of Ch. semenowi from Xinjiang (see above) likely corresponds to Ch. nigricornis .

HABITAT. In Eastern and South-Eastern Kazakhstan, the species inhabits the river banks on plains and foothills at elevations 400–1500 m.
