status

1. Median pronotal spines separated ( Fig. 2 View FIGURE 2 , B), if basally fused, then their apexes are considerably distant from each other [e.g. Trachymyrmex arizonensis ( Wheeler, 1907) ].

2. Mandible dorsum striated ( Fig. 2 View FIGURE 2 , E).

3. Preocular carinae short, frequently curved towards the frontal carinae ( Fig. 2 View FIGURE 2 , B).

4. Pilosity sparse ( Fig. 2 View FIGURE 2 , G).

5. Postocular protuberance inconspicuous ( Fig. 2 View FIGURE 2 , B).

6. Vertexal corners slightly rounded ( Fig. 2 View FIGURE 2 , E).

7. Posterior margin of head with mild median impression ( Fig. 2 View FIGURE 2 , B).

8. Postpetiole in lateral view with posteromedial impression (posterior margin concave) ( Fig. 2 View FIGURE 2 , G, I).

9. First gastral tergite generally with inconspicuous pairs of lateral and median ridges ( Fig. 2 View FIGURE 2 , I).

10. Propodeal projections spiny ( Fig. 2 View FIGURE 2 , G), rarely blunt [e.g. Trachymyrmex desertorum ( Wheeler, 1911) ]. 11. Promesonotum with subequal-sized projections ( Fig. 2 View FIGURE 2 , G).

12. Antennal scape never with basal lobe; microtubercles tiny ( Fig. 2 View FIGURE 2 , B, E).
