Myrmecia elegans

Identification
Heterick (2009) - Western Australian specimens of Myrmecia elegans are very difficult to separate from Myrmecia occidentalis, and I am unable to follow Ogata and Taylor (1991) wholly in their diagnosis of the species. The mandibles are often quite dark in colour, but can also be light yellow (they are light-coloured in M. occidentalis). The mesosoma varies from uniformly red or orange to bicoloured dark red and black, similar to M. occidentalis. The yellowish pubescence on the clypeus, as well as the shorter antennal scape, seem to be the surest guides to M. elegans, and, at least in local workers, the individual mandibular teeth tend to be slanted posteriad in M. elegans but are mostly evenly triangular in M. occidentalis.
