Polistes (Epicnemius) testaceicolor Bequaert

Paramere ( Fig. 31A View FIGURE 31 ): (1) about three times longer than wide at the middle; (2) lateral groove deep; (3) parameral spine damaged partially, with long and dense bristles on the part seen; (4) paramere lobe weakly developed and rounded; (5) inferior portion of paramere narrow, about 2/3 the width at the middle portion. Aedeagus ( Fig. 31B, C View FIGURE 31 ): slender; (1) apical portion with fine and serrated 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 (about 1/4 of the total length of apical portion); (3) median expansion weakly developed, rounded apex; (4) lateral apodeme directed forward and shorter than the ventral process, (5) ventral process rounded in apex and compressed in the base; (6) inferior portion of aedeagus weakly curved, almost straight in lateral view. Digitus ( Fig. 31D View FIGURE 31 ): slender; (1) apical process developed, almost the same size than base, (2) apex weakly rounded; apical process very curved in side; (3) anteroventral lobe long and widely rounded apically; (4) punctation strong, forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis ( Fig. 31E View FIGURE 31 ): slender; (1) apex pointed and tapering abruptly to the end; (2) long and sparse bristles, more on lateral margin; (3) punctation reduced and restricted on the lateral lobe; (4) lower part developed and more membranous.

Remarks. Richards’ (1978: 537) comments are about the genitalia with “distal expansion of aedeagus subcircular, shaft moderately narrow, ventral teeth a little longer than in P. subsericeus ” and; “digitus similar to P. subsericeus but bare”. Unfortunately, Richards did not draw the genitalia.
