Key to the identification of Neotropical workers and queens of Probolomyrmex View in CoL

1 Prora absent ( Fig. 1A View FIGURE 1 )................................................................................. 2 - Prora present ( Fig. 1B View FIGURE 1 - pr).............................................................................. 3

2 Ventral profile of the petiole with a subrectangular anterior projection. Guatemala, Mexico, and Panama ( Fig. 2A View FIGURE 2 - sp)................................................................................................ P. petiolatus View in CoL

- Ventral profile of the petiole without a subrectangular anterior projection. Argentina and Brazil (GO, MS, MT, RO, and TO) ( Fig. 2B View FIGURE 2 - sp)................................................................................. P. brujitae

3 In lateral view, dorsal and posterior margins of propodeum meeting in a rounded angle, without any acute projection. Brazil (PA) ( Fig. 3A View FIGURE 3 - pd)..................................................................... P. lamellatus sp. n.

- In lateral view, dorsal and posterior margins of propodeum meeting in an acute angle, forming distinct teeth. ( Fig. 3B View FIGURE 3 - pd)..................................................................................................... 4 4 In lateral view petiole higher than long ( Fig. 4A View FIGURE 4 ). In dorsal view petiolar teeth well developed. Brazil (PA, RO and TO) ( Fig. 17C View FIGURE 17 )................................................................................ P. dentinodis sp. n.

- In lateral view petiole longer than high ( Fig. 4B View FIGURE 4 ). In dorsal view petiolar teeth absent or weakly developed ( Fig. 21C View FIGURE 21 )...… 5 5 In lateral view, the highest point of the dorsal profile of the first gastral tergite is at the posterior limit of the tergite. Nicaragua ( Fig. 5A View FIGURE 5 )................................................................................. P. cegua sp. n.

- In lateral view, the highest point of the dorsal profile of the first gastral tergite is anterior to the posterior limit of the tergite. ( Fig. 5B View FIGURE 5 - ppd)....................................................................................... 6
