I consulted Adrian Pont who suggested Phaonia. This fly is P. lugubris.
Note for other Muscid workers: The very distinctive ventral fringe of long hairs on the fore tibia is surprisingly difficult to see. Unless one achieves precisely the correct aspect for viewing the fringe stays stubbornly out of view. It was my initial conclusion that this fly had no such fringe that led me to dismiss P. lugubris as the likely species I had before me. Image of finge below
