[Note: Latreille, 1802a: 263, and also Kempf, 1972b: 260, give Formica pusilla De Geer, 1773 as a senior synonym of Formica nana Latreille, 1802a, but the latter is also unidentifiable. Similarly, Fabricius, 1782: 491, Retzius, 1783: 76, and Fabricius, 1804: 406, give Formica pusilla De Geer, 1773 as a junior synonym of Formica omnivora Linnaeus, 1758, another unidentifiable name. It is apparent from De Geer, 1773’s pl. 31, fig. 24, that the species is a myrmicine ant.]

[Note: {ref 126800}: 263, and also {ref 126357}: 260, give {taxac 437732} as a senior synonym of {taxac 437630}, but the latter is also unidentifiable. Similarly, {ref 124871}: 491, {ref 128038}: 76, and {ref 124870}: 406, give {taxac 437732} as a junior synonym of {taxac 437668}, another unidentifiable name. It is apparent from {ref 124032}’s pl. 31, fig. 24, that the species is a myrmicine ant.]
