Eldermyrmex oblongiceps
(Wheeler, W.M., 1915)

Dlussky (1997) postulated that this species likely did not belong in Iridomyrmex and that it “... most probably should be placed into another genus ...” However, he did not erect a new genus for it as he only had Wheeler’s (1915) drawing available and did not feel this was sufficient to establish a new genus. It is clear that this species does not belong to Iridomyrmex, and is, in fact, so distinct that assignment to a separate, and new, genus seems straightforward. This genus, Eldermyrmex, was established by Shattuck (in Heterick & Shattuck, 2011).
