种属鉴别：Schmidt and Shattuck (2014) - Ectomomyrmex workers can be identified by the following combination of characters: head, mesosoma and petiole strongly sculptured, head usually prismatic posteriorly, mesopleuron divided by a transverse groove, and petiole with a sweeping posterior face. Ectomomyrmex workers are similar to those of some Ponera species (e.g., Ponera alpha), but Ectomomyrmex workers lack an anterior fenestra in the subpetiolar process and have two metatibial spurs and a divided mesopleuron. Ectomomyrmex is also superficially similar to Pachycondyla, but Ectomomyrmex lacks the complex metapleural gland orifice and hypopygial spines of Pachycondyla, and Pachycondyla lacks the prismatic head shape of Ectomomyrmex. Ectomomyrmex is also somewhat similar to Cryptopone and Pseudoponera, but differs from them in having strong sculpturing, larger eyes, no basal mandibular pit, a prismatic head, divided mesopleuron, slit-shaped propodeal spiracles, a sweeping posterior petiolar face, and no traction setae on the mesotibiae. Ectomomyrmex may be confused with Pseudoneoponera or Bothroponera, but Ectomomyrmex lacks the shaggy pilosity and longitudinally striate tergite A3 of Pseudoneoponera, and the large eyes, undivided mesopleuron, and block-like petiole of Bothroponera.
