About Myrmecia piliventris Smith, 1858
Worker Myrmecia piliventris typically measure 10–15.5 millimetres in length. Most of the body is black, while the mandibles, antennae, and legs are dark brown. The tarsi are lighter and have a more reddish tone, and the abdomen is golden yellow. Like some other species in the Myrmecia genus, Myrmecia piliventris lacks teeth, which is a trait most members of this genus do have. Its genome is similar to that of the jack jumper ant, but its chromosome complement is n=2, which is higher than that of the jack jumper ant. Most other species in the Myrmecia genus have a much higher chromosome count than Myrmecia piliventris.
