Leioproctus (Leioproctus) bicristatus (Cockerell, 1929)

Paracolletes bicristatus * Cockerell 1929d: 307 ; 1934: 22.

Paracolletes melanurus * Cockerell 1930: 47 ; 1934: 29. syn.n.

Leioproctus (Leioproctus) bicristatus (Cockerell) . Michener 1965: 50.

Leioproctus (Leioproctus) melanoproctus Michener 1965: 51 . [Replacement name for Paracolletes melanurus ] Types

Paracolletes bicristatus — Queensland: holotype ♀, Tooloom, i.1926, H. Hacker ( QM T.4098) .

Paracolletes melanurus — Queensland: holotype ♀, Tooloom, i.1926, H. Hacker ( QM T.4029) .

When Leioproctus bicristatus was described 2 females from Tooloom were mentioned; now only 1 female, the holotype can be located in the Queensland Museum. It appears the second female specimen was described 1 year later as a new species ( Paracolletes melanurus ). When Michener transferred these 2 nominal species into Leioproctus , the name " melanurus " was preoccupied by a South American species, so he replaced the name with " melanoproctus ". The holotypes of Paracolletes bicristatus and Paracolletes melanurus are identical, although the latter has lost the lateral tufts of hair on the scutellum—the most distinctive feature of this species.
