For me it is a member of the genus Lasius not Formica. Microocelli in workers of Lasius are usually absent but in some specimens present. |

I attached fragment of the key to genera identification of Formicidae by Seifert (2007) in German. Generally Lasius and Formica well differ in size. It is difficult to identify black Lasius species using only photo. They differ in subtle characters, especially setation of clypeus, number of erect setae on antennal scapus and hind tibiae, and number of setae on head and close to propodeal spiracle.
