Diagnosis.
With the exception of
S. wulongensis
, male of
S. bifurcata
can be distinguished from all other congeners by the embolus with an asymmetrically furcate end (
Fig. 6f
vs.
Fig. 6a–d,
6g
–h
), and female of
S. bifurcata
differs by the stubby, sclerotized central process (
Fig. 8A
vs.
Figs. 5C–D
,
7A–C
,
9A–B
).
S. bifurcata
similar to
S. wulongensis
in the shape of palpal bulb and the configuration of vulva, but male of
S. bifurcata
can be distinguished from that of
S. wulongensis
by the starting position of embolus (
Fig. 6F
vs.
Fig. 6E
, the position indicated by the blue arrow) and the unequal length of branches of embolic tip (
Fig. 6f
vs.
Fig. 6e
); female of
S. bifurcata
separated by the smaller, “Ω”-shaped inner vulval plate, and the shorter central process (
Fig. 8A
vs.
Fig. 8B
).
