Huemer) (Barcode TLMF Lep 20380), P. Huemer & B. Wiesmair leg. ( TLMF ); Ulagan district, 10 km NE Aktash village, Kurai Mts range, between Korumdyajry and Yarlyamry rivers, 2150 m a.s.l., 50°19′N , 87°43′E , 6.–8.viii.2016 , 9 1 ♀ , P. Huemer & B.

( NMPC ); the same data but 21.vi.2015 , 2 2 ♀♀ (gen. slide 280/17; 286/ 17♀ ; 171/18, O. Bidzilya) ( NMPC ); Belyashi (Dzhazator) env. ( 25 km NW), confluence of Argut and Karagem rivers, 49°51′56″N , 87°10′22″E , rocky steppe, 1400 m , 1 8 ♀♀ , J. Šumpich leg. ( NMPC ); Kosh-Agach Distr., Kurai env. (6.5 km SW), 50°10′35″N ; 87°53′55″E , grassy steppe, 1550 m , 30.vii.2017 , 2 ♀♀ , J. Šumpich leg. ( NMPC ). Molecular data. Genetically variable species, clustering into two BINS : BIN BOLD : ADE0005 (n = 4, 4 public, 4 from the Altai ); BOLD : ADE0329 (n = 1, from the Altai ). The average intraspecific divergence of the barcode region in BIN BOLD : ADE0005 is 0.24% (maximum 0.32%) whereas the p-distance to the second cluster is 3.56%. C. sciurella (Walsingham, [1908]) occurring on the Canary Islands and Madeira, is the nearest neighbour with 6.8% p-distance. Distribution. Turkey , Iran and central Asia ( HUEMER 1988 ), Russia : the Altai Republic . New species for Russia . Remark. Specimens of both genetic clusters occur sympatrically and fully agree in external and genitalia morphology, thus clearly indicating conspecificity. Material from the Altai Mts. is tentatively identified as C. tetrameris , a species described from Turkey which may include cryptic diversity. However, lack of material and absence of comparative genetic data do not allow a final taxonomic assessment for the time being.
