Perdita perpallida citrinella Graenicher 1910


Scientific Name: Perdita perpallida citrinella Graenicher 1910

Common Name: All-pale Perdita


Perdita citrinella Graenicher 1910: 103 [♀].

     Holotype ♀. USA, Wisconsin, St. Croix Co., North Hudson, 13 August 1909 [Milwaukee Public Museum no. 30389]. Synonymy by Timberlake (1952: 204), as a subspecies of Perdita perpallida Cockerell 1901.


Taxonomic notes: Though Crawford (1912) recoded ♀ and ♂ specimens from Alberta, Canada, the ♂ was not described until Stevens (1919: 207). Timberlake (1960: 27) considered Graenicher’s taxon a valid subspecies, which is followed here, though later indicated that it likely only represented variation in the typical form (Timberlake 1960: 27).

Distribution in Canada: Crawford 1912 [AB], Stevens 1919 [AB].

Body length: ♀ 6 mm
