Diagnosis
This species can be distinguished from all congeners in the
P. nenjukovi
species group by medially wide male chelicerae (
Fig. 4B
), by a narrow and distally blunt uncus provided with a large proximal apophysis (
Fig. 4A
), by a stick-shaped appendix (
Fig. 4A
), and by the presence of a large, prolateral membranous area distally on the procursus (arrow in
Fig. 3C
).
Etymology
The specific epithet refers to the

locality; adjective.
