Phengaris nausithous (Bergsträsser, 1779)

Germany, Hanau-Munzberg
Male similar to Phengaris teleius, but the female quite black-brown above; particularly recognizable by the underside being coffee-brown and bearing only one row of ocelli, ab. minor Frey are small specimens from Switzerland. In ab. inocellata Sohn the ocelli of the underside are reduced, in ab. lycaonius Schultz they are entirely absent. In the male ab. lucida Geest the forewing above has the blue lighter and more extended and the black discal spots reduced or obsolete.
Throughout Central Europe, from Alsatia to the Ural, Caucasus and Armenia, and from Pommerania and the Lower Rhine to Italy.
