Lycaena arion  L. f. naruena Courvoisier, 1911  ( figs. 7–9, 12 View Figure , 16C View Figure )

Courvoisier, 1911a: 202; 1911b: 108, type locality: “…aus Narün, durch Vermittlung von H. Dr. M. Wiskott…”

The type series contains Phengaris cyanecula (Eversmann, 1848)  , not P. arion (Linnaeus, 1758)  (the discal spot on the forewing upperside in males is wider, than the marginal border), and they definitely originate from the Central Asiatic mountains (large and bright wing pattern elements are characteristic for the Central Asian subspecies of this species; the typical Siberian P. cyanecula  male is figured on fig. 3 View Figure and differs very well by small wing pattern elements, the typical P. cyanecula  male from Central Asia is figured on fig. 6 View Figure ). A female specimen was figured as the type of this taxon by its author.

It is important to note that the area of P. cyanecula  does not include Europe where the locality “Narün” is located. According the last revision of the Palaearctic Phengaris ( Korb, 2011: 34)  its distribution covers “mountain regions of South Siberia and Far East, Tian-Shan, Alai, Dzhungaria, Saur, Tarbagatai, Mongolia, Central, North-Eastern and West China, North Corea ”. Thus, it is impossible to collect this species in Europe.

The type series contain 2 syntypes. To preserve the nomenclatural stability, it is necessary to designate the lectotype of this taxon. I designate this lectotype here, a female specimen ( figs. 9, 12 View Figure ), which is figured in the paper of L.G. Courvoisier (1911b: pl. 2, fig. 13 View Figure ), labelled: pink paper, printed “ TYPUS ”; pink paper, handwritten “Narün | 1909 Wisk.”; white paper, handwritten “F. naruena  m. 1910”.

The other syntype specimen, female, is designated here as paralectotype.

As we can see from the comparison we made, the type series of this taxon was definitely collected in Central Asia. In this situation the type locality “Narün” must be treated as “Naryn” and therefore the taxon belongs to the Central Asiatic fauna, with following nomenclatural implications due to the Principle of Priority: Phengaris cyanecula naruena (Courvoisier, 1911)  , stat.rev. = P. cyanecula sosinomus (Fruhstorfer, 1915)  , syn.n., = P. cyanecula sauron (Korb, 2003)  , syn.n.; type locality must be corrected as well: “Narün” (Naryn in Inner Kyrgyzstan).
