Somavilla, Alexandre, Oliveira, Marcio Luiz, Andena, Sergio Ricardo & Carpenter, James Michael, 2018, An illustrated atlas for male genitalia of the New World Polistes Latreille, 1802 (Vespidae: Polistinae), Zootaxa 4504 (3), pp. 301-344 : 338

Polistes (Onerarius) carnifex (Fabricius)

Paramere ( Fig. 39A ): (1) about two and half times longer than wide at the middle; (2) lateral groove shallow; (3) parameral spine long (about 1/6 the total length of paramere), pointed apically with very long and dense bristles; (4) paramere lobe developed and rounded; (5) inferior portion of paramere narrow, about 2/3 the width at the middle portion. Aedeagus ( Fig. 39B, C ): slender; (1) apical portion with intermediate 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, with a weakly bilobed appearance (little more than 1/3 of the total length of apical portion); (3) median expansion widely developed, pointed apex; (4) lateral apodeme directed forward with a weak central projection and shorter than the ventral process, (5) ventral process rounded; (6) inferior portion of aedeagus weakly curved, almost straight in lateral view. Digitus ( Fig. 39D ): slender; (1) apical process developed, about 1.5 times longer than the digitus base, 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. 39E ): slender; (1) apex pointed and tapering abruptly to the end; (2) long and sparse bristles, but more on lateral margin; (3) punctation restricted on the lateral lobe; (4) lower part developed with short bristles.

Remarks. Richard’s (1978: 441) description complements ours in relation to the teeth of the aedeagus: “about 27 in number”. Other structures match our description.
