• [Unresolved junior secondary homonym of Lasius emarginatus Olivier, 1792.]
• Unidentifiable taxon, incertae sedis in Lasius.
• [Note: Lasius emarginatus Olivier, 1792 and Lasius emarginatus Fabricius, 1804 are considered to be different taxa because: (i) Fabricius, 1804 does not mention Olivier in his entry for Lasius emarginatus Fabricius, 1804 (or anywhere else in his 1804 (Fabricius, 1804) publication, whereas all other previous authors are acknowledged), (ii) Fabricius, 1804 adds the information “Dom. Smidt. Mus. Dom. de Sehestedt”, which is not present in Olivier, 1792; (iii) the type localities of the Olivier, 1792 and Fabricius, 1804 taxa are very different (France and South America); (iv) Olivier, 1792 describes w.q.m. whereas Fabricius, 1804 has only q.; (v) descriptions of the queens do not match; (vi) none of Olivier’s (Olivier, 1792) 11 new species are mentioned in Fabricius, 1804.]
