Spilogona depressula

Spilogona depressula (Zetterstedt, 1845) Aricia depressula Zetterstedt, 1845: 1460. Type-locality: “ Hab. in Svecia in primis boreali rarissime; in Helsingia ad Arbrå 24 Aug. [lectotype]; in alpe Mullfjellet Jemtlandiae 27 Jul. 1840 specimina duo legi. In Smolandia etiam mense Jul. ad Skärsjö a D. Ljungh bis captam vidi. In Scania ad Lund quoque semel deprehensa.” [SWEDEN]. Limnophora (Spilogona) reflecta Huckett, 1932: 316. Type-locality: “ 1♂, Bozeman, Montana, June 14, 1916; 1♂, June 15, 1916; 1♀, June 30, 1916. (Mont. Exp. Station)” [USA, Montana]. Syn. nov. Spilogona depressula (Zetterstedt, 1845); Sorokina, 2017: 53 (Yamalo-Nenez AO); Sorokina, 2018: 237 (Altai Krai, Altai Mts); Sorokina et al., 2018: 327 (Magadan region); Tridrikh & Sorokina, 2021: 827 (Magadan region). Notes. The series of Nearctic specimens of Spilogona reflecta (in Canadian National Collection) and the series of Palaearctic specimens of Spilogona depressula were examined. The descriptions of both species and the male terminalia are the same. I can therefore conclude that Limnophora (Spilogona) reflecta Huckett, 1932 is a new junior synonym of Aricia depressula Zetterstedt, 1845. Additional material examined.
