(male holotype):

Etymology.
The specific name is derived from the
type
locality; noun in apposition.
Diagnosis.
This new species resembles
Punctus maoxian
sp. nov.
in having a similarly shaped embolus, but can be recognized by: 1) the wider retroventral tibial apophysis, with a triangular apophysis on the prolateral margin, and the wider, simple tip (vs retroventral tibial apophysis tapering from base to tip, prolateral margin smooth, and tip bifurcated, cf.
Fig. 71B–C
and
Fig. 76B–C
), 2) the longer dorsal tibial apophysis (vs short, cf.
Fig. 71C, E
and
Fig. 76E
), 3) the blunt, triangular-shaped tegular apophysis (vs arc-shaped, cf.
Fig. 71B
and
Fig. 76B
), 4) copulatory openings directed mesally, towards each other (vs directed posteriorly, cf.
Fig. 72A
and
Fig. 77A
), and 5) the round bursa (vs oval, cf.
Fig. 72B
and
Fig. 77B
).
