Subgenus Horistelops Gozis, 1910

The synonymy Horistelops = Helopondrus Reitter, 1922 was established recently ( Bouchard et al. 2021). Representatives of the subgenus are distributed in Europe, Anatolia, Western Kazakhstan (Uralsk), North Iran and South- West Turkmenistan.

Notes. In a previous paper ( NABOZHENKO 2010) we listed data on the holotypes of two species from Iran and Turkmenistan, N. cambyses ( Seidlitz, 1895) and N. ahngeri ( Medvedev, 1998) and suggested that these names could be synonymous. The original descriptions and figures for N. ahngeri are present- ed in the original descriptions ( SEIDLITZ 1895, MEDVEDEV 1998) and figures for N. cambyses are illustrated in NABOZHENKO (2010). Both taxa are conspecific, and studied specimens from Kopetdag described as N. ahngeri ( NABOZHENKO 2010) , differ only by smaller body size from populations from Elburs. As a result, the following synonymy is proposed: Helops cambyses Seidlitz, 1895 = Cylindronotus ahngeri Medvedev, 1998 , syn. n.

Nalassus (Horistelops) lineatus (Allard, 1877)

( Fig. 18 )

Material. 1 f (ED MSU): Russia, Krasnodar Region, Vityazevo near Anapa , 17– 21.04.2004 (leg. S. K. Alexeev); 7 specimens ( PCMN) : Krasnodar Region, Sochi, near Slava Metreveli stadium, 14– 15.05.2009 ; 1 f ( HNHM): Abkhazia, Klich River valley, Yuzhny Priyut , 11– 14.07.1979 (leg. K. Székely) .

Distribution in the Greater Caucasus. This species has a disjunctive range ( NABOZ- HENKO 2001). The western exclave: the Western Caucasus from Anapa ( Russia) in the north to Adzharia ( Georgia) in the south and Kaspi ( Georgia) in the east. Nalassus lineatus occurs on plains and foothills, but sometimes it reaches low mountains through canyons.
