Primary type information:
Type-material: syntype workers (number not stated), 1 syntype queen, 1 syntype male. Type-locality: Canada: Ontario, Ottawa, Cap Rouge (L. Provancher). Type-depository: unknown, perhaps in LUQC.
Type notes:
LUQC is suggested by Creighton, 1950a: 276. Before Creighton, Gahan & Rohwer, 1917a: 433, had said of Leptothorax canadensis “Type-Not located”. Later, Francoeur & Béique, 1966a: 142, apparently record 3 syntypes but fail to note the depository. The reference they give (Gahan & Rohwer, 1918a: 103) does not mention Leptothorax, but they do say that specimens in the Collège de Lévis are not syntypes of Leptothorax canadensis.
