E. Box, in “mound nest on ground.” Weber compared these specimens with “topotypes” of T. jamaicensisand “cotypes” of its subspecies. We examined two T. jamaicensis antiguensis“cotypes” (syntypes) deposited in the MZSP and noticed that both workers lack the main diagnostic feature of Trachymyrmexof the Jamaicensisgroup, the posteriorly opened antennal scrobe. We believe that these specimens actually belong to a species of the Trachymyrmex Urichigroup, to be dealt with in a forthcoming paper.
