Etymology.
The specific name is taken from the
type
locality, Yanling County; adjective.
Diagnosis.
This new species resembles
S. tumefacta
sp. nov.
(
Figs 53
A–E, 54A–D, 55A–B) in having a thin embolus with a reduced embolic apophysis and lateral lobes fused, with almost horizontal margins anteriorly, but can be separated by: 1. Male palp with dRTA narrow and dorsally digitiform (wide, bulging in
S. tumefacta
); 2. Female vulva with glandular appendages short (long in
S. tumefacta
), posterior parts of spermathecae distinctly swollen (slightly swollen in
S. tumefacta
).

Copulatory organ as in diagnosis. Epigynal field wider than long, with narrow anterior bands. Lateral lobes fused, with broadly triangular median incision. Internal ducts stout, running two thirds parallel along the median line. Glandular appendages much narrower than other parts of the duct system, postero-laterad. Fertilization ducts arising posterioly (

Colouration in ethanol. As in males, but prosoma dorsally with much more dark setae and dorsal opisthosoma dark brown (
