    T. albipes looks similar to the argentine ant (Linepithema humile) but the Argentine ant has a petiole, a verticle projection that the white-footed ant does not have. (Warner et al, 2002)
    Paratrechina bourbonica


    T. albipes can be confused with the robust crazy ant (Paratrechina bourbonica) especially in South Florida, but the robust crazy ant is slightly larger and faster moving. It also has more hair than the white-footed ant and emits a slightly fruity odor when crushed. (Warner et al, 2002)
    Technomyrmex difficilis


    Technomyrmex difficilis Forel is frequently misidentified as the white-footed ant,Technomyrmex albipes Smith (See Wetterer, 2008). According to Bolton (2007 in Wetterer, 2008) T. difficilis can be distinguished by "the presence of setae on the dorsum of the head behind the level of the posterior margin of the eye (never developed in albipes) and by having the promesonotum somewhat longer and more slender, DTI 127-135 (as opposed to DTI 110-124 in albipes)”. [DTI = Dorsal Thoracic Index = length from anterior pronotal margin to metanotal groove × 100, divided by pronotal width]
