Andrena cyanura Cockerell, 1916


Scientific Name: Andrena cyanura Cockerell, 1916

Common Name: Cyanide Mining Bee


Andrena cyanura Cockerell 1916: 252 [♀].

     Lectotype ♀, designated by Sheffield (2021: 54). USA, Colorado, Troublesome, 8 June 1908, by S.A. Rohwer, on Salix [CAS no. 15325].

Andrena transnigra paysoni Cockerell, 1924: 349 [♀]. Synonymy by Sheffield (2020: 54).

     Holotype ♀. USA, Wyoming, Chimney Rock, 17 May 1924, by C.L. Corkins [USNM no. 100707].


Taxonomic notes: The ♂ was described by Bouseman and LaBerge (1979:313), as Andrena transnigra Viereck, 1904 (see Sheffield 2021: 55).

Though Bouseman and LaBerge (1979: 314) mentioned the holotype for Andrena cyanura Cockerell, 1916, Cockerell's original work indicated two females, indicating syntypes.

Though both A. cyanura and Andrena transnigra paysoni Cockerell, 1924 were synonymized under Andrena transnigra by Bouseman and LaBerge (1979: 312), Sheffield (2021) resurrected A. cyanura and considered A. transnigra paysoni a synonym of that taxon.
