Myrmecina atlantis

Nothing is known about the biology of .

Identification
Rigato (1999) - For its sculpture this ant might be confused with a pale Myrmecina graminicola, but it shares the scape's shape of Myrmecina sicula and Myrmecina melonii. Yet, as some Myrmecina graminicola may have a cylindrical scape, one can doubt about the separation of atlantis as a distinct form. However, I have seen specimens exactly corresponding to the usual dark graminicola (also in scape's shape) and to the paler atlantis coming from the same localities of Tunisia; so these ants often appear to be sympatric without intermediates. Myrmecina melonii is also similar, but has much shorter and dentiform propodeal spines and much less strong longitudinal rugulae on the alitrunk.
