Monomorium minutum subsp. ergatogyna Wheeler, 1904e: 269 (w.q.) U.S.A. (California). Nearctic.

Primary type information: Primary type material: lectotype ergatoid queen (by designation of DuBois, 1986: 88). Primary type locality: U.S.A.: California, Catalina I., 1904 (C.F. Baker). Primary type depository: AMNH. Secondary type information: Secondary type depositories: AMNH, MCZC. Type notes: DuBois, 1986: 88, cites 33 worker, 33 queen syntypes (21w, 16q AMNH, 12w, 17q MCZC), all apparently from the type locality. This does not tally with Wheeler, 1904e’s original comment that the syntypes were “numerous workers and eight females taken from three different nests”.
