Ant Identification

[beau15415]

Hi I have just recently acquired a new queen ant after a mass nuptial flight in Queensland, Australia. I can not tell if she is Lasius Niger or irdomyrmex bicknelli. I have an alive one who is about 6 or 7 millimetres long and is a mix of brown and black with small brown stripes on her gastor. I also have a dead one too, either a dead male or female with wings still that I can send a picture of if needed but I don't know how good quality the image will be. Can anyone identify the species?
