Odontomachus quadrispinosus

Holotype worker in. Labelled “Brazil” and also with a Farren White label. It is probable that this determination is spurious, a secondary labelling by Farren White, who seems to have had a habit of throwing away original data labels and substituting his own. Also in are two quadrispinosus workers with the data, “Para 48/133.” Acc. Reg.: “1848 no. 133. Para. Bt of Stevens. Collected by Mssrs Bates & Wallace.” One of these specimens is sublabelled “172.” I suspect that all three together constituted the original syntype series.
