Notes

This species is closer to P. orientalis in having the mesosoma dorsally mostly brown or dirty yellow; longitudinal sensillae absent in F1 and F2; fore wing 2.68 × as long as wide, but differs in having s cape 6.30 × as long as wide; truncate area 0.36 × of clava length; clava 2.45 × as long as wide; postmarginal vein 1.58 × as long as stigma vein; hind wing 3.37 × as long as wide; F4 to F6 with 41 longitudinal sensillae (scape 5.60 × as long as wide; truncate area 0.60 × of clava length; clava 2 × as long as wide; postmarginal vein 2.0 × as long as stigma vein; hind wing 2.80 × as long as wide; F4 to F6 with 15 longitudinal sensilla in P. orientalis ).
