Lasius affinis ^HNS (Schenck, 1852:62)

This is an uncommon Central European species which has occurred in North Germany and Poland and also Belgium and the Netherlands. The worker is like that of L. bicornis ^HNS, but has the dorsum of the gaster as well as alitrunk crowded with long hairs and the scale with a more angular emargination. Queens and males have similar differences and are much larger than L. bicornis ^HNS.
