Diagnosis: Females of P. amicorum are recognized by the elongate epigyne with fairly small, globular spermathecae, and the absence of lobate ducts.

Etymology: The species name is a Latin genitive of ‘ amicus ’ (friend), referring to the collectors of the type material.

Description: Female (holotype, MRAC 162110). Total l 5.50.

Carapace chestnut brown, covered by tiny warts forming a network with polygonal meshes, l: 2.00; w: 1.65. Sternum warted, l: 1.00; w: 1.20. Chelicerae, pleural bars, endites, labium, and chilum covered by fine warts. Abdomen greyish brown, without do scutum. Legs orange-brown, covered by fine warts.

Leg spination: fe: I pl 0-0-0-1-1 rlv 0-0-0-0-1; III do 0-0-1; IV do 0-0-1; ti: I ve 2-2-2-2-2-2-2-2; II ve 2-2- 2-2-2-2-2-2-2; IV pl 0-1-0 rl 0-1-0; mt: I ve 2-2-2-2; II ve 2-2-2-2; III ve 0-2-0; IV rl 1-0-0 ve 0-2-1.

Epigyne ( Figs 9G, H , 38B ): posterior margin broadly protruding, with slightly sclerotized posterior rim; internal structure visible in transparency. Copulatory openings central. Copulatory ducts broad, simple, leading to small, globular, widely separated spermathecae. Without lobate ducts.

Male unknown.

Known geographical distribution: Cameroon ( Fig. 20 ).
