Megachile angelarum Cockerell 1902


Scientific Name: Megachile angelarum Cockerell 1902

Common Name: Angel Resin Bee


Megachile angelarum Cockerell, 1902: 70 [♀].

     Holotype ♀. USA, California, "So. Cal.", presumably near Los Angeles, 1893, by A. Davidson [Cockerell Collection].


Taxonomic notes: The ♂ was described by Mitchell (1937: 386).

Mitchell (1941: 166) described two gynandromorphs of Megachile angelarum Cockerell, 1902 from California. 

Snelling (1990) placed Megachile angelarum (as Chalicodoma angelarum (Cockerell)) within the M. exilis Cresson, 1872 species group.

DNA Barcode Index Number (BIN): BOLD:AAF4184

Biology: Linsley (1944: 54) recorded Sapyga fulvicornis Cresson as a nest parasite in California.

Distribution in Canada: Gibson 1917 [ON, BC, as M. exilis, subexilis Cockerell, 1908]; Buckell 1950 [BC - and records M. subexilis Cockerell from BC]; Snelling 1990 [BC]; Sheffield et al. 2011 [BC]; Sheffield and Heron 2019 [BC].

The records from Gibson (1917) from BC and ON as M. subexilis Cockerell, and M. exilis are suspected of being misidentifed specimens of M. angelarum and M. campanulae (Robertson, 1903), respectively, as neither of the former have been confirmed from Canada.
