FIGURE 11 A, B) P. d e a Santschi. Lateral view of minor worker (A), illustrating second mesonotal process at same level as dorsopropodeum, postpetiole relatively small in relation to petiole; full-face view of major worker (B): vertex without crossmeshes and posterolateral lobes longitudinally rugose. C, D) P. s e m i d e a sp. n. Lateral view of minor worker (C), showing second mesonotal process raised at slightly higher level than dorsopropodeum, postpetiole relatively larger in relation to petiole; full-face view of major worker (D): vertex with cross-meshes and posterolateral lobes obliquely and irregularly rugulose.
