Polistes (Fuscopolistes) rossi Bohart

Paramere (Fig. 38A): (1) about two and half times longer than wide at the middle; (2) lateral groove deep; almost straight; (3) parameral spine medium (about 1/7 the total length of paramere), pointed apically with long and sparse bristles, mainly on spine base; (4) paramere lobe weakly developed and rounded; (5) inferior portion of paramere narrow, about a half the width at the middle portion. Aedeagus (Fig. 38B, C): robust; (1) apical portion with prominent denticulation, extended from the penis valve to the end of median expansion, lateral margin curved; (2) penis valve dilated and with a strong central entrance (about 1/3 of the total length of apical portion); (3) median expansion developed and pointed apex; (4) lateral apodeme directed forward and shorter than ventral process, (5) ventral process very rounded and compressed in the base; (6) inferior portion of aedeagus weakly curved, almost straight in lateral view; (7) with about 24 small, uniform, ventral teeth, four or more of the most anterior ones more or less fused. Digitus (Fig. 38D): robust; (1) apical process very reduced; (3) anteroventral lobe long and pointed apically; (4) punctation strong, over the entire digitus base; (5) short and dense bristles, mainly on lateral margin. Cuspis (Fig. 38E): robust, triangular-shape; (1) apex weakly pointed and tapering gradually to the end; (2) long and dense bristles on cuspis; (3) punctation restricted on the lateral lobe; (4) lower part weakly developed and more membranous aspect.

Remarks. Richards (1978: 456) commented about the aedeagus having about 24 small teeth and “digitus rather small, narrowed posteriorly in dorsal view, distal process of moderate length, not densely hairy”.
