Perdita (Perdita) dolichocephala Swenk and Cockerell, 1907

Counties: Anoka.

Comments: This species, known from only four females and nine males collected at one location in eastern Minnesota, represents a large range expansion, with the previous closest records from Nebraska ( Timberlake 1960). These specimens were found in the same location where the only specimens of the western species Andrena haynesi were also found nesting in deep sand (see above). To confirm the identification, the Minnesota specimens were compared to the holotype and several other specimens of P. dolichocephala deposited at the University of Nebraska State Museum, as well as some specimens of the similar species P. laticincta Swenk and Cockerell, 1907 and P. tridentata Stevens, 1919 , deposited at the J.B. Wallis /R.E. Roughley Museum of Entomology and the University of Nebraska State Museum, respectively. A fifth female was photographed at the same location by J. Gardner on 5 Sep. 2015 and uploaded to BugGuide.net (https://bugguide.net/node/view/1306651).
