Polistes (Aphanilopterus) canadensis Linnaeus

Paramere ( Fig. 6A View FIGURE 6 ): (1) about three times longer than wide at the middle and strongly curved; (2) lateral groove shallow, more pronounced on the upper part; (3) parameral spine medium (about 1/7 the total length of paramere), pointed apically with long and dense bristles; (4) parameral lobe developed and widely rounded; (5) inferior portion of paramere narrow, about 0,8 the width at the middle portion. Aedeagus ( Fig. 6B, C View FIGURE 6 ): 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 (a little more than 1/2 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. 6D View FIGURE 6 ): slender; (1) apical process developed, about 1.5 times longer than the digitus base, strongly curved for the side, same width from the base to the apex, (2) apex pointed; (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. 6E View FIGURE 6 ): slender; (1) apex pointed and tapering abruptly to the end; (2) long and dense bristles on lateral margin and not long in the rest of cuspis; (3) punctation restricted on the lateral lobe; (4) lower part developed with short bristles.

Remarks. Richards (1978: 492) did not describe the male genitalia of this species, but he pointed out that the male is “very like the female but slightly smaller”.
