October 18, 2019, Bali, Tabanan, Kediri, Pantai Kedungu. On bark of a small mimosa-like tree (widely-introduced American
Leucaena leucocephala) on the edge of a banana plantation. Size about 6mm. Typical wing-flashing behaviour, when disturbed it returned to the same spot in an hour, after my next attempt to catch it the fly simply moved to a position higher up the tree trunk so I couldn't reach it. I think it belongs to
linocierae group sensu Hancock & Drew, 2004 (Australian Entomologist, 31(4): 164) and fits the description of
E. songkhla from Thailand quite well (Hancock & Drew, 1994: Raffles Bull. Zool. 42(3): 572-574; syn.
maculifemur Hardy, 1973, not de Meijere, 1924).

October 22, 2019, roughly the same location, this time again on a small tree, edge of freshwater
Sonneratia mangroves, a couple of attempts to catch it with same unfortunate result. In both pictures it's clearly visible that fore basitarsus is "broad, rather flat [...], greater in width than tibia and concave on posterior surface" (Hardy, 1973).
