Remarks. The sex association of T. selligera was based on couples collected in Trinidad, as well as large numbers of both sexes co-ocurring in various areas in the northern Amazon. There are several female specimens of T. selligera in various collections identified as T. aequinidialis by Mickel, PRB, and KAW. This was a name given by Mickel to the females of T. selligera , considered as a putative new species by the author at the time. The anterolateral angles of the pronotum and the sculpture of the lateral propodeal face in the females seem to be unique within the species-group and are only approximated by the females of T. guayaca which differ in the structure of the lateral pronotal face and scutellar armature. The males of T. selligera , on the other hand, are similar in structure to those of T. tristis , differing mainly in structure of the scutellum.
