Trachymyrmex jamaicensis antiguensis Weber , 1938

Weber (1938) described T. jamaicensis antiguensis based on a “dozen” workers taken on Long Island, Antigua, British West Indies, in May 7, 1936, by Mr. H. E. Box, in “mound nest on ground.” Weber compared these specimens with “topotypes” of T. jamaicensis and “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 Trachymyrmex of the Jamaicensis group, the posteriorly opened antennal scrobe. We believe that these specimens actually belong to a species of the Trachymyrmex Urichi group, to be dealt with in a forthcoming paper.
