pe-taxon #18
This is an interesting taxon with a very distinctive, dark patch of bristles on the underside of tergites 4 & 5 – rather like a broad Sturmia-spot.
EDIT (09/10/2010): This vaguely resembles a Masiphya, with its Sturmia-spot and a few other bristle arrangements – but it has to many differences for me to place it more than ‘related to’.
