Taxonomy

Triepeolus subalpinus Cockerell, 1910: 245 [♀]

     Holotype ♀.  USA, Colorado, Boulder County, Eldora, 18-19 August [no year provided], by T.D.A. Cockerell, on Grindelia (subalpina) [USNM no. 100037]

     Holotype ♀. USA, Colorado, Garfield County, Glenwood Springs, about 39 33’N 107 20’W, 5800 ft., 22–29 July 1919 [ANMH no. 25093]

Triepeolus stricklandi Cockerell, 1937: 86 [♀] [synonymy by Rightmyer 2008: 117]

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.

 

Biology

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).
