Polistes (Aphanilopterus) peruvianus Bequaert

Paramere ( Fig. 17A ): (1) about three times longer than wide at the middle; (2) lateral groove deep, more pronounced on the upper part; (3) parameral spine short (about 1/10 the total length of paramere), pointed apically with short and sparse bristles; (4) paramere lobe developed and widely rounded; (5) inferior portion of paramere narrow, about 2/3 the width at the middle portion. Aedeagus ( Fig. 17B, C ): slender; (1) apical portion with fine denticulation, extended only on the apical portion, lateral margin straight; (2) penis valve weakly dilated and with a slight central entrance (less than 1/3 of the total length of apical portion); (3) median expansion widely developed, rounded apex; (4) lateral apodeme directed forward with a weak central projection and shorter than the ventral process, (5) ventral process rounded and expanded in apex; (6) inferior portion of aedeagus weakly curved, almost straight in lateral view. Digitus ( Fig. 17D ): slender; (1) apical process developed, about 1.5 times 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 and forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis ( Fig. 17E ): slender; (1) apex pointed and tapering abruptly to the end; (2) short and sparse bristles, more long on lateral margin; (3) punctation restricted on the lateral lobe; (4) lower part developed with short bristles.

Remarks. Richards (1978: 504) did not describe the male genitalia of this species. He commented about the external features.
