Need help in identifying this large ant species

[qwerty264]

Hi, 2 months ago, i caught this very large queen ant. I keep on seeing large ant workers outside in the garden that are the same species. It has a dark red head, black thorax and black gaster with a tinge of gold. The workers have long legs and ive also seen supermajors that have VERY huge head and about the same body size as the queen. Often see them on leaves and pavements around my house. Queen size is about 2 cm from head to gaster and workers are about 1.5 cm. Please help me identify the species. Thanks!
