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 : 332-333

Polistes (Fuscopolistes) dorsalis (Fabricius)

Paramere: (1) about two and half times longer than wide at the middle; (2) lateral groove shallow; (3) parameral spine medium (about 1/7 the total length of paramere), pointed apically with long and dense bristles; (4) paramere lobe weakly developed and rounded; (5) inferior portion of paramere not narrow, about 0,7 the width at the middle portion. Aedeagus: robust; (1) apical portion with prominent denticulation, extended to the penis valve to the end of median expansion, lateral margin curved; (2) penis valve dilated and with a weakly central entrance, weakly bilobed (about 1/3 of the total length of apical portion); (3) median expansion developed and pointed apex; (4) lateral apodeme directed forward and almost the same size as the ventral process, (5) ventral process rounded and weakly compressed in base; (6) inferior portion of aedeagus weakly curved, almost straight in lateral view; (7) ventral teeth uniform, about 20 in number. Digitus: robust; (1) apical process very reduced; (2) anteroventral lobe long and pointed apically, very distinctive groove of the anteroventral lobe, which is bordered on each side by a carina; (3) punctation strong, over the entire digitus base; (4) short and sparse bristles, mainly on lateral margin. Cuspis: not seen.

Remarks. In Richards (1978: 457–458), P. dorsalis was divided into five subspecies; his general comments (p. 457) are about the expanded tip of aedeagus being rather long and the ventral teeth very small, uniform, about 20 in number. Buck et al. (2012) presented illustrations of the paramere ( Fig. 16 ), digitus ( Fig. 24 ) and aedeagus ( Figs. 41 , 49, 57), which match our description.
