Polistes (Aphanilopterus) kaibabensis Hayward

Paramere (Fig. 13A): (1) about three times longer than wide at the middle; (2) lateral groove shallow; (3)

parameral spine long (about 1/6 the total length of paramere), pointed apically with long and dense bristles; (4) paramere lobe developed and pointed; (5) inferior portion of paramere narrow, about 2/3 the width at the middle portion. Aedeagus (Fig. 13B, C): 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 weakly dilated and with a slight central entrance (about 1/3 of the total length of apical portion); (3) median expansion widely developed, weakly pointed apex; (4) lateral apodeme directed forward, with a weak central projection and almost the same size at the ventral process, (5) ventral process rounded and slightly dilated in apex; (6) inferior portion of aedeagus weakly curved, almost straight, in lateral view. Digitus (Fig. 13D): slender; (1) apical process developed, about twice longer than the digitus base, same width from the base to the apex, (2) apex rounded; (3) anteroventral lobe short and rounded apically; (4) punctation strong, forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis (Fig. 13E): slender; (1) apex pointed and tapering abruptly to the end; (2) long and dense bristles, mainly on lateral margin; (3) punctation restricted on the lateral lobe; (4) lower part developed with short bristles.

Remarks. Richards (1978) did not mention the male genitalia for this species.
