Polistes (Epicnemius) claripennis Ducke

Paramere: (1) about three times longer than wide at the middle; (2) lateral groove deep, more pronounced on the upper part; (3) parameral spine long (about 1/6 the total length of paramere), pointed apically with long and sparse bristles; (4) paramere lobe developed and weakly pointed; (5) inferior portion of paramere narrow, about 2/3 the width at the middle portion. Aedeagus: slender; (1) apical portion with fine and serrated denticulation, extended the apex of the apical portion to the median expansion, lateral margin straight; (2) penis valve not observed; (3) median expansion developed and rounded apex; (4) lateral apodeme directed forward and shorter than the ventral process; (6) inferior portion of aedeagus curved, in lateral view. Digitus: slender; (1) apical process developed, about twice longer than the digitus base and expanded at the apex, (2) apex pointed, apical process strongly curved for the side; (3) anteroventral lobe developed widely rounded apically; (4) punctation strong, forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis: slender; (1) apex very pointed and tapering abruptly to the end; (2) short and sparse bristles on cuspis; (3) punctation restricted on the lateral lobe; (4) lower part weakly developed.

Remarks. Richards (1978: 538) commented about the denticulation, as “not very small” with 24 teeth and ventral teeth acute. Unfortunately, Richards did not draw the genitalia.
