This is a French Guianan bombylid photographed by Stephane Brule - can it be identified? :)

Oh itīs amazing! I hope anyone can identify it, just a few "lost steps" looking drawings of books
- the most similiar wing at Palaearctic seems Exoprosopa pectoralis, it has yellow face
but black frons :( (Engel, 1938)
- another similar wing pattern: Diatropomma, related to Isomyia but both have a narrow wing base and are Etiopian :(( ("Exoprosopinae", Hull, 1973)
- at bugguide:
http://bugguide.n...96/bgimage
- page 159, figure "f" Poecilanthrax
http://redalyc.ua...523111.pdf
- "nearest" ones in keys for eastern (US) are Exoprosopa and Dipalta
Could "Exoprosopini" be said at least? :(
regards :)

This is Hyperalonia morio ssp. erythrocephala (Fabricius). Great shot!

There are several taxa of Neotropical Stratiomyidae with similar colouration. Does anyone know whether this is mimicry of some kind, and which could be the supposed models? I cannot remember having seen stinging aculeates in S-America with such colours...

Many thanks Neal - all credit for the photo goes to Stephane Brule in French Guiana :)
As Menno says, the coloration (with the bluish ground colour and yellow head) does remind me of a few of those stratiomyids that are common in the same region -
Cyphomyia? Here is another of Stephane's photos (of
Cyphomyia):

Yes, those are the ones I mean. And if I remember correctly there is also another (unrelated?) stratiomyid genus looking like this.
Of course there doesn't need to be an aculeate model: if one or more of these flies just taste very bad, they may also benefit from looking like each other (Mullerian mimicry or a combination of different types of mimicry...)
