Diagnosis.

Among the darker coloured species with unicolorous (brown to black) flagellomeres, P. floridakeys is unique in having the propodeum with an almost complete areola (all other species lack an areola).

Description.

Metacoxa: mostly black to dark brown (posterior 0.1-0.2 yellow). Malar distance: less than 0.2 × eye length. Fore wing areolet: absent. T1 sculpture: anterior 0.5 smooth, posterior 0.5 sculptured. T2 sculpture: mostly smooth. Body length: 2.30-2.50 mm. Fore wing length: 2.40-2.55 mm. Ovipositor length: 1.50-1.70 mm. Ocular-ocellar line: 0.12 mm. Interocellar distance: 0.09 mm. Posterior ocellus diameter: 0.06 mm. Metacoxa length: 0.51-0.56 mm. Metafemur length: 0.61-0.65 mm. Metatibia length: 0.71-0.77 mm. T1 length/width at posterior margin: 0.33-0.35 mm/ 0.14 mm.
