Key to the Polistes species occurring in the Philippine Islands
The characters used are applicable to both sexes unless the sex is specified.
1. Clypeus latero-dorsally not or scarcely extending beyond the anterior tentorial pits. Pronotal fovea present. Mesepisternum with dorsal mesepisternal groove...................................................... 2 (Subgenus Gyrostoma )
- Clypeus latero-dorsally extending far above the anterior tentorial pits. Pronotal fovea absent. Mesepisternum without dorsal mesepisternal groove and epicnemial carina............................................... 3 (Subgenus Polistella )
2. Male clypeus apically rounded to truncate, with flattened disc ( Fig. 3 View FIGURES 1–4 ). Male mandible simple. Male gena as broad as eye at ocular sinus ( Fig. 4 View FIGURES 1–4 ). Last flagellomere of male curved and tapering only at apex ( Fig. 5 View FIGURES 5–6 ). Pronotal carina of female not lamellate. Posterior depression of female propodeum broad and shallow ( Fig. 6 View FIGURES 5–6 ). T1 broader than long and strongly curved dorsally. Body entirely black, wings orange ( Figs. 1–2 View FIGURES 1–4 ), male face extensively yellow ( Fig. 3 View FIGURES 1–4 )....... P. (G.) nigrosericans Bequaert
- Male clypeus apically with a sharp median toot and medially depressed ( Fig 8 View FIGURES 7–11 ). Male mandible bulging basally. Male gena 1.5× as broad as eye at ocular sinus ( Fig. 9 View FIGURES 7–11 ). Last flagellomere of male straight and tapering from base to apex ( Fig. 10 View FIGURES 7–11 ). Pronotal carina of female elevated and shortly lamellate. Posterior depression of female propodeum narrower and deeper ( Fig. 11 View FIGURES 7–11 ). T1 longer than broad and weakly curved dorsally. Body black with orange band on metasomal segments ( Fig. 7 View FIGURES 7–11 ), male coloration of face not known in Philippine forms........................................ P. (G.) tenebricosus Lepeletier
3. Small-sized wasp. Marginal cell of fore wing with dark spot ( Fig. 46 View FIGURES 43–46 )........................ P. (P.) stigma (Fabricius)
- Medium-sized to large-sized wasps. Marginal cell of fore wing without dark spot.................................. 4
4. Pronotum with striations ( Figs. 42 View FIGURES 38–42 , 52 View FIGURES 47–52 ).................................................................... 5
- Pronotum punctate, not striate.......................................................................... 6
5. Pronotal striation strong and regular. Border between dorsal and lateral faces of pronotum angled ( Fig. 51 View FIGURES 47–52 ). Male S7 with a median tubercle ( Fig. 53 View FIGURES 53–56 ).................................................... P. (P.) strigosus mimus Bequaert

6. Mesosoma sparsely punctate, punctures not touching each other. Female metasomal sterna without longitudinal ridges.... 7

7. Distance between posterior ocelli greater than ocellus diameter. Jugal lobe not reduced. T1 as long as its apical width in dorsal view. S2 of female more strongly convex in lateral view ( Fig. 58 View FIGURES 57–62 ). Male antenna not elongate, similar to female antenna and with median flagellomeres broadened ( Fig. 60 View FIGURES 57–62 ). S7 of male with obliquely cut off semicircular area margined with black thick bristles ( Fig. 61 View FIGURES 57–62 ). Body light red with extensive yellow markings and some reduced black areas..................................................................................................... P. (P.) tenuipunctatus sp. nov.
- Distance between posterior ocelli smaller than ocellus diameter. Jugal lobe reduced. T1 longer than its apical width in dorsal view. S2 of female weakly convex in lateral view ( Fig. 27 View FIGURES 27–31 ). Male antenna elongate and without broadened segments ( Figs. 30 View FIGURES 27–31 , 66 View FIGURES 63–66 ). S7 without obliquely cut off area ( Fig. 31 View FIGURES 27–31 ). Body reddish-brown with narrow pale markings...................... 8
