Common Name: Obliterated Longhorn Cuckoo Bee


Triepeolus obliteratus Graenicher, 1911: 242 [♀, ♂].

     Syntypes ♀, ♂. USA, Wisconsin, Burnett Co., mouth of the Yellow River, 28-31 July 1909 [♀, Public Museum of Milwaukee no. 29595]; Wisconsin, Pierce Col, Prescott, 13-19 July 1910 [♂, Public Museum of Milwaukee no. 39317].

Biology: Shapiro and Droege (2011: 62) indicate this as a nest parasite of Melissodes Latreille, 1825; Veit et al. (2022) reported this species as a nest parasite of Melissodes apicatus Lovell and Cockerell, 1906, an oligolege of pickerweed recorded from Ontario and Quebec in Canada.

Distribution in Canada: Sheffield et al. 2014 [SK]; Woodcock et al. 2014 [ON]; Normandin et al. 2017 [QC]; Gibbs et al. 2023 [MB]

This species was tentatively recorded from Ontario by Woodcock et al. (2014), and from Quebec by Normandin et al. (2017). Though the species was not specifically stated, Rightmyer (2008) indicated that the Triepeolus simplex species group occurred in Saskatchewan, which is supported here.
