 reaching to near the apex of the metatarsus ; claws bifid. 

 Radial cellule not much longer than deep, narrowed rather 

 sharply in the middle. The first transverse cubital nervure

Identical in the colour of the body and wings to P. vivax ; 

 differing in the second cubital cellule not being petiolate ; 

 the scutellum and apex of median segment not bearing a 

 dense pubescence ; in the ocelli forming a triangle and the 

 posterior being, if anything, separated from the eyes by a 

 somewhat greater distance than they are from each other ; 

 in the clypeus being rounded ; in the occiput being slightly 

 convex ; in the median segment being widely and deeply 

 furrowed down the centre, in the spurs being shorter (three- 

 fourths of the length of the metatarsus) and black. The 

 abdominal segments have a broad belt of greyish pruinose 

 pubescence on the apex. The legs are pruinose ; the spines 

 short, petiole moderately narrow at the base, becoming 

 gradually wider towards the apex.
