Scientific Name: Dufourea maura (Cresson, 1878)

Common Name: Black Shortface Bee


Panurgus maurus Cresson, 1878: 61 [♀ = ♂]

     Lectotype ♂, designated by Cresson (1916: 123). USA, Colorado, by H.K. Morrison [ASNP no. 2210].

DNA Barcode Index Number (BIN): BOLD:AAC6943

BiologyDufourea maura (Cresson, 1878) is an oligolege of Campanula Linnaeus (Campanulaceae) (Stevens 1919; Moldenke and Lincoln 1979; Lincoln 1981; Arduser 1986; Dumesh and Sheffield 2012; Gibbs et al. 2014); Arduser (1986) indicating that C. rotundifolia and other related and widespread species are likely the main floral hosts.

Bohart (1943) and Kathirithamby and Taylor (2005) reported Dufourea maura as the host for strepsipteran Eurystylops tetonensis Bohart, 1943; the genus Eurystylops seemingly specializes on Dufourea Lepeletier, 1841and other rophitine bees (Bohart 1943; Bohart and Irwin 1978).

Distribution in Canada: Cockerell 1911 [SK]; Gibson 1911 [SK]; Dumesh and Sheffield 2012 [BC [no data], AB, MB, ON]; Sheffield et al. 2014 [AB, MB]; Gibbs et al. 2023 [MB]; RSKM [BC].

Arduser (1986) reported this species from northern Michigan. Gibbs et al. (2014) indicated that this boreal/alpine species was likely not to occur in southern parts of that state, or elsewhere in the eastern United States; it was not included in Mitchell’s (1960) treatment of bees of the eastern United States.

Body length: ♀ ♀ 9.5-10 mm; ♂‚ 10 mm
