This looks to be an Atomosia sp. (male). This is a huge neotropical genus; species-level identifications are generally not possible at present.
These small asilids are are members of the group Atomosiini, which is variously treated as either a tribe of the subfamily Laphriinae or as an independent subfamily Atomosiinae.
