Diagnostic Features.
This new lycosid spider closely resembles
Pardosa astrigera
C.L.Koch,
1878
in the color pattern of carapace and
Lycosa yunnanensis
Yin, Peng and Wang,
1996
in the shape of the posterior margin of septum but differs from both taxa in (
1
) leg formula and spination in tibia IV, (
2
) leg II as long as III, (
3
) epigynum ratio of a/b =
0.71
, (
4
) strongly C-shaped guide pocket, (
5
) distinctly cleft posterior epigynal margin, and (
6
) eye measurements.
Etymology.
Patronym, in recognition of Dr. Song Daxian’s outstanding contributions in the spider systematics of
China
.
