( Fig. 3BView FIGURE 3 - pd)..................................................................................................... 4 4 In lateral view petiole higher than long ( Fig. 4AView FIGURE 4). In dorsal view petiolar teeth well developed. Brazil (PA, RO and TO) ( Fig. 17CView FIGURE 17)................................................................................ P. dentinodis  sp. n.

In dorsal view petiolar teeth absent or weakly developed ( Fig. 21CView 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. 5AView 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. 5BView FIGURE 5 - ppd)....................................................................................... 6
