The first photo shows very clearly the setulae, seta(e),[= bristle(s)] and maybe some spur(s) = spine(s)?

Yeah, that was an unorthodox view :D

Certainly a female Linnaemyia but, after Theo's warning on this genus, I wouldn't like to say which species it was. :)

maybe L. tesselans? :)

Whatever it Linnaemyia is, this is a magnificent fly!

what is the function of those many bristles and spurs in legs? It looks a little like an ancient roman chariot with metallic spurs on wheels... to cut something. :o

I'd guess it is sensory ... most bristles articulate in cups, which in turn contain a lot of nerves. But it's hard to understand exactly how the fly uses the data it gets from the bristles. Could be for sensing host movement or helping judge air-speed and direction in flight.

I'll stick to my own warning.
Tessellans, though, seems highly unlikely to me

so will it remain for now Linnaemyia sp. ?

Theo, tell me which characters I must see to get ID species.

Impossible, too subtle. Sorry
