Polistes (Aphanilopterus) cavapyta de Saussure

Paramere ( Fig. 7A ): (1) about three times longer than wide at the middle; (2) lateral groove deep, more pronounced on the upper part; (3) parameral spine long (about 1/6 the total length of paramere), pointed apically with long and dense bristles; (4) parameral lobe developed and rounded; (5) inferior portion of paramere narrow, about half the width at the middle portion. Aedeagus ( Fig. 7B, C ): slender; (1) apical portion with fine and serrated denticulation, extended from the apex of the apical portion to the 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 widely developed, rounded apex; (4) lateral apodeme directed forward and shorter than the ventral process, (5) ventral process rounded and weakly dilated; (6) inferior portion of aedeagus curved, in lateral view. Digitus ( Fig. 7D ): 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 and forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis ( Fig. 7E ): slender; (1) apex pointed and tapering abruptly to the end; (2) long and dense bristles on cuspis; (3) punctation restricted on the lateral lobe; (4) lower part developed with short bristles.

Remarks. Richards (1978: 479) did not depict the male genitalia of this species. He commented only that the hairs on the base of digitus were very few, the ventral process “rather” pointed and “genitalia rather small”.
