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 : 333-334

Polistes (Fuscopolistes) flavus Cresson

Paramere ( Fig. 34A ): (1) about two and half times longer than wide at the middle; (2) lateral groove deep; (3) parameral spine long (about 1/6 the total length of paramere), apically pointed with short and dense bristles, mainly on spine base; (4) paramere lobe developed and rounded; (5) inferior portion of paramere wide, about 0,8 the width at the middle portion. Aedeagus ( Fig. 34B, C ): robust; (1) apical portion with prominent denticulation, with small teeth interspersed between the large, extended to the penis valve to the end of median expansion, lateral margin curved; (2) penis valve dilated and with a strong central entrance, bilobed (about 1/3 of the total length of apical portion); (3) median expansion developed and pointed apex; (4) lateral apodeme directed forward, with a weak central projection and almost the same size as the ventral process, (5) ventral process rounded and slightly expanded in apex; (6) inferior portion of aedeagus weakly curved, almost straight in lateral view; (7) ventral teeth uniform, about 24 in number with some further rudimentary. Digitus ( Fig. 34D ): robust; (1) apical process very reduced; (3) anteroventral lobe long and pointed apically; (4) punctation strong, over the entire digitus base; (5) short and dense bristles, mainly on lateral margin. Cuspis ( Fig. 34E ): robust, triangular-shape; (1) apex weakly pointed and tapering gradually to the end; (2) short and sparse bristles on cuspis; (3) punctation restricted on the lateral lobe; (4) lower part developed and more membranous aspect, with short bristles.

Remarks. Richards’ (1978: 459) comments were: “distal expansion of aedeagus short, ventral teeth small, of uniform size, about 24 in number with some further rudimentary ones at each end; digitus with basal portion not very large, narrowed posteriorly, distal process short”.
