Diagnosis: Males of P. gevaertsi are recognized by the small RTA with short broad base and thin spine, the sclerotized embolus, MA, and FC, which are all straight, tapered and parallel to each other. Females are characterized by the epigyne with a small recurved frontal fold and a transverse fold spanning the entire epigynal width in front of the posterior margin.

Etymology: The species name is a patronym in honour of Hugo Gevaerts who supports scientific research in Kisangani, DR Congo.
