Daerlac nigricans, family Rhyparochromidae, body length 10mm 
Yes, this is a true bug. Its body colour and behaviour is mimicking the black ant. It was found wandering on a large gum tree trunk, where a lot of black ants is running around. It did not have the waist, which is the characteristic of all ants, but its body colour pattern mimics just exactly this. From our reference books, ant-mimic bug could be lygaeids, alydids or mirids. From its head and antenna it looks like a lygaeids,  Then we found that it is in this Rhyparochromidae family, which is very close to Lygaeidae.
