Colletes gilensis Cockerell, 1897


Scientific Name: Colletes gilensis Cockerell, 1897

Common Name: Colletes gilensis


Colletes gilensis Cockerell, 1897 [♂].

     Syntype ♂♂. USA, New Mexico, west fork of Gila River, 16 July [no year provided], by C.H.T. Townsend [] 


Taxonomic notes: The location of the type material (2♂s) is unknown, according to Stephen (1954: 219); Swenk (1908: 24) indicated that the syntypes were in the Cockerell Collection (Entomology Collection of the University of Colorado Museum of Natural History), and the other at Academy of Natural Sciences [ANSP] (Philadelphia), though neither institution has material listed in online databases of type material.

The ♀ was first recognized by Cockerell (1901: 125, described the mouthparts) and Cockerell (1904: 6), but not fully described until done so by Swenk (1908: 23).

Distribution in Canada: Gibson 1914 (BC).

Its presence in Canada has not been confirmed, as Sheffield and Heron (2019) incidated that the record of this species in BC by Gibson (1914: 124) from Similkameen, Okanagan (11 September 1913, by Tom Wilson) was likely a misidentification. Stephen (1954: 214) indicated that this is a species of the southwestern USA and northern Mexico. Stephen (1954: 214) indicated it was most similar to C. compactus Cresson, a species that does occur in the province. 

Body length: ♀ 14.5 mm ♂ 14 mm

Forewing length: ♀ 11 mm ♂ 10 mm
