Polistes (Aphanilopterus) weyrauchorum Willink

Paramere ( Fig. 21A ): (1) about three times longer than wide at the middle; (2) lateral groove shallow, 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) paramere lobe developed and widely rounded; (5) inferior portion of paramere narrow, about 2/3 the width at the middle portion. Aedeagus ( Fig. 21B, C ): slender; (1) apical portion with fine 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, pointed apex; (4) lateral apodeme directed forward and shorter than the ventral process, (5) ventral process rounded and slightly dilated in apex; (6) inferior portion of aedeagus curved, in lateral view. Digitus ( Fig. 21D ): 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 weak and forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis ( Fig. 21E ): slender; (1) apex pointed and tapering abruptly to the end; (2) long and sparse bristles; (3) punctation reduced and restricted on the lateral lobe; (4) lower part developed and more membranous with short and dense bristles.

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