Polistes (Aphanilopterus) biguttatus Haliday

Paramere ( Fig. 4A ): (1) about three times longer than wide at the middle; (2) lateral groove weakly deep, more pronounced on the upper part; (3) parameral spine long (about 1/6 the total length of paramere), pointed apically with short and sparse bristles, mainly on spine base; (4) paramere lobe developed and widely rounded; (5) inferior portion of paramere narrow, about half the width at the middle portion. Aedeagus ( Fig. 4B, 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 and shorter than the ventral process; (5) ventral process rounded and expanded in apex; (6) inferior portion of aedeagus curved, in lateral view. Digitus ( Fig. 4D ): 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 larger on the side of the base; (5) short and sparse bristles. Cuspis ( Fig. 4E ): 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 weakly developed.

Remarks. Richards (1978: Fig. 140) depicted only the digitus and the aedeagus. His drawings do not allow us to compare the denticulation, which is present only on the apical portion (see Fig. 4 B and C ).
