I'll try again, since my photo did not seem to get uploaded, but it may be seen at this link <https://www.dropbox.com/s/ecxf1ocd6o8cro7/Mesochaetopterus%202181-07.jpg?dl=0> as well.
In the meantime Marco Faasse, even without seeing the photo, guessed it was Mesochaetopterus and I find very similar photos on the web indeed. Confirmation of the species is much appreciated.
Kind regards
