Polistes (Epicnemius) actaeon Haliday

Paramere ( Fig. 23A ): (1) about three times longer than wide at the middle; (2) lateral groove deep; (3) parameral spine very long (about 1/5 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 half the width at the middle portion. Aedeagus ( Fig. 23B, C ): slender; (1) apical portion with fine and serrated denticulation, extended 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 developed and rounded apex; (4) lateral apodeme directed forward and shorter than the ventral process, (5) ventral process rounded and slightly expanded in apex; (6) inferior portion of aedeagus weakly curved, almost straight in lateral view. Digitus ( Fig. 23D ): slender; (1) apical process developed, about twice longer than the digitus base, and slightly expanded at the apex, (2) apex rounded; (3) anteroventral lobe short and rounded apically; (4) punctation larger on the side of the base; (5) long and dense bristles in the base and short and sparse in the apical process. Cuspis ( Fig. 23E ): slender; (1) apex pointed and tapering abruptly to the end; (2) long and sparse bristles on cuspis, more on the lateral margin; (3) punctation restricted on the lateral lobe; (4) lower part weakly developed.

Remarks. Richards (1978: 550–551) did not describe the male genitalia of this species, but he pointed out

“Both sexes structurally similar to P. pacificus , including the male genitalia”.
