Notes:

Some of the above mentioned records most probably include also closely related Lasius platythorax . Lasius niger alienoniger Forel, 1874 has been considered by different authors to be a separate species or a junior synonym of Lasius niger, but Seifert (1992) proposed it should be considered as incertae sedis in Lasius (for details see Bolton 1995, Bolton et al. 2006).
