Agonopterix agyrella (Rebel, 1917)

( Figs 25–29 )

Material examined. RUSSIA: ALTAI REPUBLIC: Kosh-Agach Distr., Kurai env. (6.5 km SW), 50°10′35″N, 87°53′55″E, grassy steppe, 1550 m, 30.vii.2017, 1 Ƌ (gen. prep. DEEUR 7669 P. Buchner), (Barcode NMPC-LEP-0154), J. Šumpich leg. ( 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, 27.–28.vii.2017, 1 ♀ (Barcode NMPC- -LEP-0156), J. Šumpich leg. ( NMPC); Katun Valley, 51°40′N, 85°45′E, 600 m, 1.vii.2001, 1 Ƌ ( DEEUR 6456), K. Nupponen leg. ( RCKN).

Molecular data. BIN BOLD: AAF 7185 (n = 25; 10 public, 3 from Altai). The average intraspecific divergence of the barcode region is 0.44% (maximum 1.29%). However, this BIN is shared also with Agonopterix putridella (Denis & Schiffermuller, 1775) , A. septicella Snellen, 1884 and several hitherto unidentified Agonopterix specimens from the A. putridella / agyrella group, where all Altaic A. agyrella records are clustered with no variability in barcodes.

Distribution. Asian part of Russia (Novosibirsk Region, Altai, Primorsky krai), Mongolia, China ( LVOVSKY 2006). From the Russian Altai this species was also published by HUEMER et al. (2017) as Agonopterix sp. 1.

Remarks. Agonopterix agyrella was described based on a single male from eastern Tannu-Ola mountains in southern Siberia in Russia ( Figs 27, 29 ). This holotype was successfully barcoded by the NGS method (sample ID NHMW2.Lep. 0001) where all three Altaic specimens have 100% match with its barcode. These three specimens also correspond with the type of A. agyrella in genitalia and external appearance, which confirms their conspecificity ( Figs 28–29 ). On the other hand, the intraspecific variability of A. agyrella is poorly known, and although it differs in external appearance from the related taxa very well, it is possible to expect taxonomic changes in the A. putridella /agyrella species group in the future. Barcoding of the specimen from Katun Valley (DEEUR 6456 P. Buchner) failed, therefore its identification based only on the characters in genitalia must be considered provisional for the moment.
