Taxonomy
Colletes nigrifrons Titus, 1900: 304 [♀]
Lectotype ♀ [designated by Stephen (1954)]. USA, Colorado, Pinecliffe, 9 July 1949, by R.H. Beamer [KESM]
Colletes florissantia Cockerell, 1906e: 425 [♂‚] [synonymy by Timberlake (1943)]

Holotype ♂‚. USA, Colorado, Florissant, 27 June [no year provided], on Polemonium [CAS; Citrus Experiment Station, Riverside]
Notes on Type Material: Titus (1900) originally described C. nigrifrons from two ♀ specimens from Ft. Collins, Colorado [6 August 1996, by Gillette], and Horsetooth Mt., Colorado [22 June 1999, on Potentilla]. This material is seemingly lost, as Stephen (1954) designated a lectotype ♀ (see above) and a neallotype ♂‚ from Salida, Colorado [4 July 1949, by L.D. Beamer], both in the Snow Entomological Collections as University of Kansas. Timberlake (1943) does not mention the type material of C. nigrifrons when he made the synonymies indicated above.
