ď (paratype from Therison, V.82). Length: 13.8 mm; fore wing length: 10.7 mm.

Intraspecific variation. Examined: 2♀, 2♂. Length: 13.6–13.7 (♀); 12.6–13.8 mm (♂); fore wing length: 9.6–11.1 mm (♀); 9.4–10.7 mm (♂); ovipositor length 1.0–1.1x fore wing length. One of the two male paratypes has the fore leg entirely reddish orange.

Distribution. Crete Island, Greece.

Remarks. This new species is easily identified by several distinctive morphological features: shape and sculpture of the head and sculpture of the mesosoma, which is shiny with a few carinae. As P. gloriator , the new species has a narrow occipital carina, pronotum without teeth, and four teeth on the inner margin of the claw; however, it can be distinguished by several characters reported in Table 3.
