Etymology.
This specific name is derived from the
type
locality; noun in apposition.
Diagnosis.
This new species resembles
P. splendidus
(Song & Zheng, 1992)
in having a similarly shaped retroventral tibial apophysis, but can be recognized by: 1) the thinner, needle-shaped embolus (vs thick, nubbyshaped, cf.
Fig. 59C
and fig. 3H in
Kamura [2021]
), and 2) the shorter, rod-like tegular apophysis (vs arc-shaped, cf.
Fig. 59C
and fig. 3K in
Kamura [2021]
).
