Myrmecia varians

Identification
Little separates M. varians from Myrmecia michaelseni and Myrmecia rugosa, but Ogata and Taylor (1991) use subtle differences in the length of the pronotal setae and the appearance of the mandibles to distinguish them.

Distribution
Heterick (2009) - Myrmecia varians, described from the eastern states, is represented by one specimen each from Nerren Nerren Stn, just outside the boundaries of the SWBP (McKenzie, Keighery et al. 2000) and from Westonia.
