Taxonomic notes: Though Swenk (1913: 113) synonymized Viereckella ceanothina Cockerell, 1907 under Epeoloides pilosulus (Cresson, 1878), he, and later Crawford (1917: 167) felt that Epeoloides obscura (Swenk, 1907) was a valid species, and it was recognized as such (e.g., Linsley and Michener 1939: 295; Linsley 1951: 1218; Hurd 1979: 2087) until 2004 when it was synonymized under Epeoloides pilosulus by C.D. Michener (in Sheffield et al. 2004: 162), though he suspected this earlier (Michener 2000: 655).

DNA Barcode Index Number (BIN): BOLD:AAL0612

Biology: This species is presumed to be a nest parasite of Macropis nuda (Provancher, 1882) in Canada based on the well-known associations between the more abundant European species (Epeoloides coecutiens, and its two confirmed Macropis hosts, Macropis europaea Warncke, 1973 and Macropis fulvipes (Fabricius, 1804) [Pekkarinen et al. 2003; Bogusch 2003, 2005; Celary 2004]); as well as historical (see Ascher 2005) and recent (Sheffield et al. 2004; Wagner and Ascher 2008; Sheffield and Heron 2018; Gibbs et al. 2021) co-occurrence of host and cuckoo in and near host’s food plant patches.

Distribution in Canada: Provancher 1888 [QC, as Nomia compacta Provancher]; Cockerell 1898 [Canada, as Nomia compacta Provancher; treatment of Nomia]; Criddle et al. 1924 [MB, QC]; Sheffield et al. 2004 [NS], 2014 [SK, MB]; Sheffield and Heron 2018 [AB, SK, MB, ON, QC, NS]; Gibbs et al. 2021 [MB], 2023 [MB].

Though earlier records for Canada existed (see above), Linsley (1951: 1218) did not record this species from Canada. There is a single observation of this species from New Brunswick on iNaturalist (https://www.inaturalist.org/observations/173998390).
