Acrocerid #2 (Lasia sp.)

I originally thought that this fly was from the family Nemestrinidae but Eric Fisher has kindly corrected my and it is in fact an acrocerid – possibly of the genus Lasia. The body length is about 14mm and, as you can see, the proboscis is even longer than that! Lasia spp. are parasitoids of mygalomorph (“bird-eating” or “tarantula”) spiders.
