"The referee has absolutely killed it to allow their winning goal because Arteta was clearly offside on two occasions," said Hughes.
"I've been to see the referee in his dressing room and he has created some cock and bull story about Ryan Nelsen being off the pitch. I've no idea what he is going on about because Ryan Nelsen, at no stage, went off the field of play. It has cost us the point."
QPR have the chance to record their first win of the season next Sunday when they host Reading at Loftus Road.
