Rather large 2cm predator fly with extended 'tail'

A number of these large flies were praying on smaller stuff / mid day / in the low altitude rainforest sections of SE Brazilian Rainforest

This is, for sure, a robber fly (Diptera, Asilidae). My guess is that this one belongs to the Genus Promachus.

Here is a photo of Promachus rufipes (from North America) for comparison:

Coincidentally, even the prey (a wasp) is in the same position of the one in your photo!

This Genus has 9 species. If this is in fact Promachus, you'll have to find out which are found in South America.
