I'm not conviced at all : ) compare: http://www.robberflies.info/keyger/htmle/lapvul.html

With Laphria species from the flava group (including vulpina) hair on the abdomen should be erect which is not the case, hair is adpressed. Also the very long postsutural hair of Laphria is not present on the mesonotum of this one.

As i mentioned before, it looks like a a head of a Laphria species on a choerades body. (not just the mesonotum also the abdomen, hair is adpressed in opposition the erect hairs of both L. vulpina and L. flava. Besides that, the shiny hairs on the face are not always obvious in Choerades, depending on the direction the light comes from. I therefore would suggest another species of which i only have seen pictures of collected specimens. : Choerades cf castellanii. Description by Hradsky fits quite well (admittedly the head remains strange) compare: http://www.biolib.cz/en/image/id238096/

I still hope that someone like Dysmachus or Danny Wolff would react. It is quite possible we will never know.
