Diagnosis: Males of P. bilobata   are characterized by the long, curved RTA, the very large MA, and FC with hooked tip. Females are recognized by the epigyne with a long bilobate posterior margin.

Etymology: The species name is an adjective referring to the lobes of the posterior margin of the epigyne.
