Formica caerulescens Losana 1834

This taxon has been described from Piemont / Italy and has been considered by all authors since Mayr (1863) as junior synonym of Tapinoma erraticum —for the last time by Radchenko (2016). However, the verbal statement of Losana (1834) “...squama subquadrata, emarginata...” and his drawings of petiole scale and dorsal aspect of the whole ant definitely exclude that it belongs to the genus Tapinoma . It is a member of the subfamily Formicinae — most probably either a species of Lasius Fabricius 1804 or Formica Linnaeus 1758 .
