Properties
Scientific Name: Diadasia australis australis (Cresson, 1878)
Common Name: Cactus Chimney Bee
Taxonomy
Melissodes australis Cresson, 1878: 214 [♀, ♂].
Lectotype ♀, designated by Cresson (1916: 112). USA, Colorado [ANSP no. 2356].

Taxonomic notes: Cockerell (1939: 60) considered his Diadasia australis petrinus Cockerell, 1923 a form of D. rinconis Cockerell, 1897, though at the time of the original description (i.e., Cockerell 1923: 84) he also considered the latter a subspecies of D. australis (Cresson, 1878) (as he has since Cockerell 1905); Timberlake (1941: 3) followed Cockerell’s (Cockerell 1939) classification. Adlakha (1969: 145) did not examine D. australis petrinus but indicated that Michener (1951: 1220) also considered it a subspecific taxon of D. rinconis, but it is not formally included in that work (i.e., Michener 1951) or subsequent versions of the catalogue (i.e., Hurd 1979) as it is known from Mexico (Lower California). Both D. australis petrinus and D. australis californica Timberlake are currently considered valid subspecies of D. australis (Ascher and Pickerling 2023), which is tentatively followed here; only the typical form occurs in Canada.
DNA Barcode Index Number (BIN): BOLD:AAC3232.
Distribution in Canada: Gibson 1919 [AB]; Sheffield et al. 2014 [AB, MB, SK, as D. enavata (Cresson)]; Sheffield and Heron 2019 [BC]; Gibbs et al. 2023 [MB].
