The ground color of the fourth pair of legs is bluish grey, with a black patch proximally.

The distinguishing features between these two species include the following: the band on the femur of leg I in P. hanumavilasumica is notably broader than that in P. fasciata.

In P. hanumavilasumica the band on the femur of leg IV forms a continuous line, while in P. fasciata, it appears disjointed.

P. hanumavilasumica can be easily distinguished from other species within the same radiation group, such as P. regalis and P. rajaei, due to the presence of a ventral abdominal band.

The close proximity of Mannar island to India suggests that the species may have dispersed over the land bridge between the two countries in the Pleistocene epoch.
