Perdita bruneri Cockerell, 1897


Scientific Name: Perdita bruneri Cockerell, 1897

Common Name: Bruner's Fairy Bee


Perdita bruneri Cockerell 1897: 23 [♂, not ♀].

     Lectotype ♂, designated by Crawford (1915: 108). USA, Nebraska, West Point, August 1887, by L. Bruner [USNM no. 5841?].

Perdita Cockerelli Crawford 1906: 282 [♂, ♀]. Synonymy by Crawford (1915: 109).

     Syntypes ♂, ♀. USA, Nebraska, West Point, [14 August 1903], by J.C. Crawford, on Grindiella squarosa, in copula [USNM no. 13890].


Taxonomic notes: Perdita cockerelli Crawford was described from multipe pairs taken in copula, but Crawford (1906: 282) never designated a specific type pair. Crawford (1906: 282) indicated that P. cockerelli was originally identified as a “larger than usual” specimen of P. bruneri, though indicated that P. bruneri females always fave a square supraclypeal mark, which is not the case, as the female of P. bruneri was later described as P. swenki Crawford, 1915. Perdita bruneri has the supraclypeal mark reduced to two spots, or entire absent (Crawford 1906: 283; Timberlake 1960: 11), the latter is the case with the female cotype specimen of P. cockerelli. Cockerell (1922: 9) confirmed Crawford’s synonymy.

DNA Barcode Index Number (BIN): BOLD:AAB2707

Interestingly, this BIN is shared with Perdita octomaculata (Say), a species more common in the east, though ranging as far west as Manitoba (Gibbs et al. 2023). Though Sheffield et al. (2014) recorded P. octomaculata from Saskatchewan (based on material in BOLD from Maple Creek (i.e., CCDB-06703 G07; CCDB-06703 G08), these may be P. bruneri.
