Polistes (Palisotius) paraguayensis Bertoni

Paramere ( Fig. 42A ): (1) about three times longer than wide at the middle; (2) lateral groove deep; (3) parameral spine long (about 1/6 total length of paramere), pointed apically and inclined slightly to the side with very long and sparse bristles; (4) paramere lobe widely developed and rounded; (5) inferior portion narrowing gradually to the base of paramere, about a half the width at the middle portion. Aedeagus ( Fig. 42B, C ): robust; (1) apical portion with intermediate and serrated denticulation, extended on the apical portion to the end of median expansion, lateral margin straight; (2) penis valve weakly dilated and with a slight central entrance (about 1/3 of the total length of apical portion); (3) median expansion developed, rounded apex; (4) lateral apodeme directed forward, with a weak central projection and shorter then ventral process, (5) ventral process rounded and dilated in apex; (6) inferior portion of aedeagus curved, in lateral view. Digitus ( Fig. 42D ): slender; (1) apical process developed, about twice longer than the digitus base, same width from the base to the apex, (2) apex rounded; (3) anteroventral lobe short and rounded apically; (4) punctation strong, forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis ( Fig. 42E ): slender; (1) apex pointed and tapering abruptly to the end; (2) short and sparse bristles, more on lateral margin; (3) punctation restricted on the lateral lobe; (4) lower part developed and membranous aspect with short bristles.

Remarks. Richards (1978: 449) did not describe the genitalia of this species. He commented that the genitalia were “not really different from those of P. major but smaller, distal process of digitus in side view a little wider”.
