Colletes consors pascoensis Cockerell, 1898


Scientific Name: Colletes consors pascoensis Cockerell, 1898

Common Name: Partner Plasterer Bee


Colletes pascoensis Cockerell, 1898g: 51 [♂, ♀]. Synonymy of C. consors by Timberlake (1943: 388).

     Syntypes ♂, ♀. USA, Washington, Pasco, 25 June 1896, by T. Kincaid [USNM no. 4273].


Taxonomic notes: Though Stephen (1954: 416) mentioned that the holotype of C. pascoensis was at the USNM, he did not indicate its sex so it cannot count as a valid lectotype designation as it is unclear which specimen Cockerell (1898) intended as the holotype (the ♂ is described first, but the syntype series consists of 3 ♀s and 4 ♂s; at the USNM, a ♂ specimen is represented as the type, though not as the holotype.

Though Timberlake (1951: 184) later questioned if pascoensis warranted subspecies status, he maintained it, which was later supported by Stephen (1954: 415).

Distribution in Canada: Stephen 1954 [BC]; Hurd 1979 [BC].

Body length: ♀ 11 mm ♂ 9.5 mm

Forewing length: ♀ 7 mm ♂ 6.5 mm
