Perdita pallidipennis Graenicher, 1910: 101 [♀, ♂].

     Lectotype ♂, designated by Portman et al. (2023: 24), USA, Wisconsin, Burnett County, Yellow River, 28-31 July 1909, No. 31731 [MPM no. ENT6390].

Perdita (Cockerellia) bequaerti Viereck, 1917 [241]. Synonymy by Portman et al. (2023: 24).

Perdita albipennis palidipennis Sugar et al., 1998 : 11. Lapsus of Perdita albipennis pallidipennis Graenicher, 1910.


Taxonomic notes: Portman et al. (2023: 24) indicated that users of Mitchell’s (1960) key in the west will likely misidentify P. albipennis s. l. as “P. a. pallidipennis” Graenicher (= P. pallidipennis s. l.), and that all Cockerellia Ashmead treated by Mitchell (1960) likely represent variation within P. pallidipennis s. l. (Portman et al. 2023). Perdita pallidipennis apparently is an eastern species occurring as far north as Massachusetts and New York (Portman et al. 2023, citing Roch et al. 2021), though material identified from Ontario P. albipennis palidipennis Graenicher by Sugar et al. (1998: 11) and as P. (C.) bequaerti bequaerti Viereck, 1917 by Paiero and Buck (2003: 142) likely also is P. pallidipennis, as recorded here.

DNA Barcode Index Number (BIN): BOLD:AAI2392

This BIN is shared with Perdita albipennis canadensis Crawford 1912.

Distribution in Canada: Sugar et al. 1998 [ON, as P. albipennis palidipennis Graenicher, claim first record for Canada]; Paiero and Buck 2003 [ON, as P. (C.) bequaerti bequaerti Viereck, 1917].
