Polysphincta pichincha sp. nov. closely resembles A. sinearanea Pádua, 2018 and P. inca sp. nov. mainly by coloration with body orange and the last tergites black. It differs from P. sinearanea by having epomia absent (present in P. sinearanea), and from P. inca sp. nov. by having malar space 0.4 times as long as proximal mandibular width (malar space >0.6 times as long as proximal mandibular width in P. inca sp. nov.).

Polysphincta shabui can be distinguished from other species of the P. dizardi species-group by the combination of the following characteristics: (1) epomia absent (Fig. 8B); (2) malar space 0.6 times as long as proximal mandibular width (Fig. 8B); (3) fore wing vein 1cu-a more or less interstitial relative to M&RS (Fig. 8A); (4) mesosoma entirely reddish brown (Fig. 8A); (5) wings hyaline (Fig. 8A); (6) hind leg orange with femur, tibia and tarsus darkish brown (or femur reddish orange) (Fig. 8A); (7) metasoma entirely darkish brown or darkish brown with tergites I–III reddish orange with posterior margins narrowly black (Fig. 8A, C); (8) ovipositor slender, 1.2–1.4 times as long as hind tibia.
