Callophrys (Ahlbergia) ferrea (Butler, 1866)

Figs 10–12

MATERIAL EXAMINED. 1 ♂, voucher No CAL165, GenBank accession No. PP 130632, Russia: Kunashir Island, 4.5 km NW Mendeleevo airport, Tretyakovo village, 19. V 2021, S. Rybalkin leg. ( AKM) .

RESULTS AND DISCUSSION. Analysis of the genitalia of the specimen in question revealed their similarity with that of the specimens from Japan studied during our previous revision ( Krupitsky et al., 2023b), namely the valvae gradually pointed to apices (in bilobed configuration) and the cornuti with numerous small spines. Compared to the specimens from Japan, the valva of the analyzed specimen is somewhat longer, but fits into the individual variation of the genitalia of Ahlbergia .

The COI barcode of the specimen in question differs by 1.67% from C. (A.) korea from Primorsky Krai, Russia (GenBank accession No. OQ701610 ) , and from South Korea (GenBank accession No. GU 372579), and it is identical to those of two analyzed specimens of C. (A.) ferrea from Hokkaido, Japan (GenBank No. OM630560 – OM630561 ) .

Taking into account these results, we confirm the presence of C. (A.) ferrea on Kunashir Island. We can not exclude the possibility of the presence of the latter species on other islands of the southern Kuril Islands Archipelago. Thus, four species of the subgenus Ahlbergia have been recorded in Russia to date: C. (A.) frivaldszkyi, C. (A.) confusa (Huang, Chen & Li, 2006), C. (A.) korea and C. (A.) ferrea.
