Thank you Paul and Kahis.
P.S. Jere, I formulated your specialisation as " around aquatic Brachycera excluding Hilara". Now I have to change it as " including Empididae too":).
P.P.S. Should I understand your silence about Horse-faced Empidida(http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=973), that it is neither Hilara nor Clinocera?
