Species Notes

This it the type species for subgenus Scaphandrena (Lanham 1949: 200). The male was known by Lanham (1987, 1993), but has not been described. In the past it has been considered a subspecies of A. scurra (Linsley 1951: 1080), and placed into synonymy with what Ribble (1973, 1974) and later Hurd (1979: ) considered a hybrid of Andrena scurra x A. arabis Robertson x A. capricornis, an idea initially supported by Lanham (1981), though later abandoned (Lanham 1984, 1987, 1993); elsewhere it is considered a possible synonymy of A. scurra (Ascher and Pickering 2018). The only occurrances known from Canada are those recorded by Buckell (1949).

The DNA Barcode Index Number (BIN) for this species is BOLD:ADY2988.
