Polistes (Aphanilopterus) cavapytiformis Richards

Paramere (Fig. 8A): (1) about three times longer than wide at the middle; (2) lateral groove shalow, more pronounced on the upper part; (3) parameral spine long (about 1/6 the total length of paramere), pointed apically with long and sparse bristles; (4) paramere lobe widely developed and rounded; (5) inferior portion of paramere narrow, about 2/3 the width at the middle portion. Aedeagus (Fig. 8B, 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 (less than 1/3 of the total length of apical portion); (3) median expansion widely developed, rounded apex; (4) lateral apodeme directed forward and almost the same size as the ventral process, (5) ventral process rounded and weakly dilated, almost straight; (6) inferior portion of aedeagus curved, in lateral view. Digitus (Fig. 8D): 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. 8E): 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: 481) did not mention the male genitalia of this species, although his description of the male adult is very precise.
