Taxonomic notes: Viereck (1917: 368) described Andrena (Andrena) angustitarsata race huardi Viereck, 1917 as an ochreous form of Andrena angustitarsata Viereck, 1904, but in that same year it was recorded as a valid species, Andrena huardi Viereck, 1917, by Bray (1917: 99). Linsley (1951: 1068), Hurd (1979: 1829), and Gusenleitner and Schwarz (2002: 85) subsequently also considered it valid. Its actual placement remains uncertain, as LaBerge (1989) did not include it as a synonym or a valid species in his revision of the subgenus Simandrena Pérez, 1890. Kathirithamby and Taylor (2005) treated it as a subspecies of A. angustitarsata as a host to strepsipteran parasites, though bee nomenclature in that work is treated rathr poorly. J.S. Ascher (see Ascher and Pickering 2024) lists it as a “possible unpublished synonym” but without indicating the reasoning. However, LaBerge (1989: 22) did indicate that some ♀s have dark ochracous pubescence, as described by Viereck (1917: 368), these individuals not restricted geographically, lending support to the tentative synonymy recorded above (but see comments below).

When Cockerell (1918: 165) described Andrena opacissima Cockerell, 1918, he indicated that it was nearest to Andrena mustelicolor Viereck, 1904 and Andrena nudiscopa (Viereck, 1904), the latter which was subsequently synonymized under Andrena angustitarsata Viereck, 1904 by Cockerell (1936: 145). LaBerge (1989: 18) listed Andrena mustelicolor as a junior synonym of A. angustitarsata, though did not record it as a new synonym. However, it was considered a valid species up until Hurd (1979). Thus, LaBerge (1989) is here credited for the synonymy. LaBerge (1989) also treated Andrena opacissima as a new synonymy of A. angustitarsata, but indicated that they could not locate, thus did not examine, the holotype.

LaBerge (1989: 18) placed A. opaciventris Cockerell into synonymy under A. angustitarsata, but indicated that he was unable to find the type material; he mentioned it should be at Pomona College at Claremont (no. 197) (LaBerge 1898: 22). It was subsequently reported at CAS (Gusenleitner and Schwarz 2002: 85).

LaBerge’s (1989: 22) incorrectly recorded the date of collection for the holotype of P. nudiscopa Viereck as 2 April 1897; this is assumed to be 1899 based on Viereck’s original listing.

DNA Barcode Index Number (BIN): BOLD:AAD9427, BOLD:AAL9743

There are two BINs assigned to this species. Most species have been assigned to BIN BOLD:AAD9427, including those from BC.

One female specimen identified as A. angustitarsata from Washington States has been assigned to BIN BOLD:AAL9743 (a second specimen did not sequence). Barcode Gap Analysis indicates that this sequence differs from A. angustitarsata by 5.27%. In addition, the Washington specimens differ morphologically from typical A. angustitarsata by the shape of the labral process, that of A. angustitarsata being wider at apex than the medial length, while the specimens from Washington have the apex narrower than the medial length; it may correspond to Andrena huardi Viereck, 1917. Preliminary analysis suggests it is sister taxa to A. angustitarsata among the North American Simandrena for which sequences are available.

Distribution in Canada: Criddle et al. 1924 [BC]; LaBerge 1989 [BC]; Elwell 2012 [BC]; Sheffield and Heron 2019 [BC].
