Polistes (Palisotius) palmarum Bequaert

Paramere ( Fig. 41A ): (1) about three times longer than wide at the middle; (2) lateral groove very shallow, almost straight; (3) parameral spine long (about 1/6 the total length of paramere), pointed apically and inclined slightly to the side with very long and dense bristles; (4) paramere lobe widely developed and rounded; (5) inferior portion narrowing gradually to the base of paramere, about a half the width at the middle portion. Aedeagus ( Fig. 41B, C ): robust; (1) apical portion with intermediate 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, with a weakly bilobed appearance (little more than 1/3 of the total length of apical portion); (3) median expansion widely developed, pointed apex; (4) lateral apodeme directed forward and almost the same size than ventral process, (5) ventral process rounded and dilated in apex and slightly compressed in base; (6) inferior portion of aedeagus curved, in lateral view. Digitus ( Fig. 41D ): slender; (1) apical process developed, about twice longer than the digitus base, same width from the base to the apex and straight, (2) apex rounded; (3) anteroventral lobe short and rounded apically; (4) punctation strong and forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis ( Fig. 41E ): slender; (1) apex pointed and tapering abruptly to the end; (2) long and sparse bristles, more on lateral margin; (3) punctation restricted on the lateral lobe; (4) lower part developed and membranous aspect.

Remarks. Richards (1978: 447) did not depict the genitalia of this species, which he treated as a subspecies of P. major . He noted only the ventral teeth of aedeagus were figured by Bohart & Bechtel (1957).
