Species Notes

This species is known globally from eastern Canada (Rightmyer 2008).

The DNA Barcode Index Number (BIN) for this species is BOLD:AAE8463, which is shared with T. subalpinus Cockerell, 1910, and another larger, undescribed species from Saskatchewan.



Little is known about the biology of this species though presumably it is a nest parasite of the eucerine genus Melissodes. In Nova Scotia, this species co-occurs with Melissodes druriellus (Kirby, 1802).



♀ body length: 8-10 mm; intertegular width: 1.9 mm; head length:  mm; head width:  mm; forewing length:  mm

♂‚ body length: 10 mm; intertegular width: 1.9 mm; head length:  mm; head width:  mm; forewing length:  mm


Approximate Global Extent of Occurrence (EOO) (http://geocat.kew.org/): 18,695.5 km2

Index of Area of Occupancy (IAO) in Canada (http://geocat.kew.org/): 112 km2
