Polistes (Fuscopolistes) apachus de Saussure

Paramere ( Fig. 33A ): (1) about two and half times longer than wide at the middle; (2) lateral groove shallow; (3) parameral spine medium (about 1/8 the total length of paramere), pointed apically with short and dense bristles; (4) paramere lobe weakly developed and rounded; (5) inferior portion of paramere narrow, about 0,8 the width at the middle portion. Aedeagus ( Fig. 33B, C ): robust; (1) apical portion with prominent denticulation, with small teeth interspersed between the large, extended from 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) v 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 slightly expanded in apex, but with a slight constriction in the initial part; (6) inferior portion of aedeagus weakly curved, almost straight in lateral view; (7) ventral teeth uniform, about 22 in number. Digitus ( Fig. 33D ): 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 in the base, mainly on the lateral margin. Cuspis ( Fig. 33E ): 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.

Remarks. In Richards (1978: 459), comments are about the genitalia with expanded tip of aedeagus rather long; ventral teeth very small, about 22 in number, digitus with basal portion rather narrow, distal process long. Here we saw small teett between large ones.
