Species Notes

This species is extremely similar to T. brittaini Cockerell (both species share the same BIN), but this species has the paramedian band present on the mesoscutum in both sexes, and the metasomal banding is broader and the mesepisternal punctation is denser than in T. brittaini. In Canada, this species is found in BC, AB, and SK, while T. brittaini is globally restricted to NB and NS. 

The DNA Barcode Index Number (BIN) for this species is BOLD:AAE8463, and is shared with T. brittaini.



This presumed host of this species was speculated to be Melissodes (Eumelissodes) agilis Cresson, as adults of both species were collected on the same flowers (Hurd et al. 1980).
