ABSTRACT

A new species of Aulacigaster Macquart, 1835 A. zurqui sp. nov., is described from Costa Rica. The new species, which is classified in the plesiomorphica species group following a cladistics analysis, can be separated from all congeners by having a triangular 1st flagellomere and stout body that is uniformly dark-brown to black. An expanded diagnosis of the plesiomorphica group and a modified key to the Neotropical Aulacigaster are provided to accommodate the new species.
