Etymology.
This specific name is derived from the
type
locality; noun in apposition.
Diagnosis.
This new species resembles
Punctus taibai
sp. nov.
in having a similarly shaped embolus, but can be recognized by: 1) the thin retroventral tibial apophysis, tapering from the base to the tip, with a smooth prolateral margin and bifurcated tip (vs retroventral tibial apophysis wide, with a triangular apophysis on the prolateral margin, and wide, not bifurcate tip, compare
Fig. 76B–C
with
Fig. 71B–C
), 2) the short dorsal tibial apophysis (vs long, compare
Fig. 76E
with
Fig. 71C, E
), 3) the arc-shaped tegular apophysis (vs blunt triangular-shaped, compare
Fig. 76B
with
Fig. 71B
), 4) copulatory openings concealed in anterior margins of concavities (vs directed mesally, towards each other, compare
Fig. 77A
with
Fig. 72A
), 5) the oval bursa (vs round, compare
Fig. 77B
with
Fig. 72B
).
