Agapostemon obliquus (Provancher, 1888)


Scientific Name: Agapostemon obliquus (Provancher, 1888)

Common Name: Oblique Striped Sweat Bee


Augochlora obliqua Provancher, 1888: 318 [♀].

     Lectotype ♀, designated by Sheffield and Perron (2014: 130). CANADA,  British Columbia, Vancouver [ULQC no. 1477].

Agapostemon Cockerelli Crawford, 1901: 161 [♀]. Synonymy by Janjic and Packer (2003: 104).

     Holotype ♀. USA, New Mexico, Mesilla Park, 30 April 1900, by T.D.A. Cockerell, on Fallugia paradoxa acuminata [USNM no. 18957].


Taxonomic notes: Sandhouse (1937: 79), Michener (1951: 1126), Hurd (1979: 1949) did not treat Provancher’s species in their treatments of augochlorine bees, seemingly not aware it was actually a species of Agapostemon Guérin-Méneville, 1844. Moure and Hurd (1987: 205) were the first to correctly place Augochlora obliqua Provancher, 1888 within Agapostemon, though as a possible synonym of A. texanus Cresson, 1872. Janjic and Packer (2003: 104) correctly recognized it as the valid name for A. cockerelli Crawford, 1901.

The ♂ was first described as A. cockerelli by Cockerell (1927: 155) from material collected in Arizona. Roberts (1972: 471) also indicated that the male paratypes of A. martini Cockerell, 1927 were also A. cockerelli, and fully described both sexes.

DNA Barcode Index Number (BIN): BOLD:AAB0974

This BIN is shared with Agapostemon femoratus Crawford, 1901 and Agapostemon sericeus (Forster, 1771).

Distribution in Canada: Provancher 1888 [BC, though he did consider it "extra limina"]; Sandhouse 1936 [BC, AB]; Michener 1951 [BC]; Sheffield et al. 2014 [AB, likely misidentification, see below]; Sheffield and Heron 2019 [BC].

Though Provancher (1888: 318) indicated that the type locality was Vancouver, it seems unlikley due to the known distribution of this species (i.e., Roberts 1972, 1973, as A. cockerelli). Several of the species described by Provancher were not labelled with collection information, and he received material from California (Los Angeles area) which could have been incorrectly associated with the specimens in this case. More work is required to verify its presence in Canada, including specimens recorded from Alberta. Sandhouse (1936: 80) listed A. cockerelli Crawford from BC and AB, though it is likely that these records represent some of the other species that she incorrectly synonymized under A. cockerelli which do occur in the BC. However, the AB specimen in question was collected more recently (1992) by C.D. Michener.
