Description
Male (holotype, Figs

,

A). Total length 7.55. Carapace 4.19 long and 3.83 wide, earthy yellow in ethanol (slightly lighter than in life), margin and fovea colour darker, without obvious dark stripes between coxal elevations (Fig.
7
A). Eye sizes and interdistances: AME 0.06, ALE 0.49, PME 0.25, PLE 0.35, AME-AME 0.08, AME-ALE 0.08, PME-PME 0.04, PME-PLE 0.06, AME-PME 0.02, ALE-PLE 0.05. Chelicerae reduced, brown, with several short macrosetae. Labium 0.73 long and 0.44 wide, fused with sternum. Sternum 1.98 long and 0.75 wide, posterior tip elongated. Opisthosoma 3.54 long and 2.29 wide, with ten tergites. Leg measurements: leg I 11.86 (3.26, 3.85, 3.17, 1.58), leg II 13.46 (3.83, 4.07, 3.51, 2.05), leg III 14.88 (3.53, 4.30, 4.47, 2.58), leg IV 19.41 (4.69, 5.51, 5.91, 3.30).
Palp (Figs
2
,
3
b
,
4
). Tibial apophysis of palp almost as high as wide, situated near retrolateral margin of tibia, with four megaspines. Cymbium with two clavate trichobothria retrolaterally (Fig.
4
D). Paracymbium large and thick, almost as wide as cymbium, cumulus distinctly elevated with many long setae (Fig.
4
). Subtegulum curved in prolaterodorsal and ventral views, without obvious apophysis. Tegulum with a well-developed and denticulate distal edge. Half of the contrategulum strongly sclerotised, with a ventral process (Figs
2
,
3
b
). Paraembolic plate slightly elevated. Embolus partly sclerotised, with some longitudinal ridges extending to the tip, margins of these ridges slightly dentated (Figs
2
,
3
b
).
Female (paratype, Figs
1
,
5
,
7
B). Total length 10.32. Carapace 4.87 long, 4.16 wide, colour as in males, except shades being darker (Figs
1
,
7
B). Eye sizes and interdistances: AME 0.06, ALE 0.45, PME 0.27, PLE 0.31, AME-AME 0.06, AME-ALE 0.07, PME-PME 0.04, PME-PLE 0.05, AME-PME 0.04, ALE-PLE 0.05. Chelicerae robust, reddish-brown, with a few short stripes on dorsal side and several long macrosetae on retrolateral edge of fang groove. Labium 1.03 long, 0.52 wide. Sternum 242 long, 1.23 wide. Opisthosoma 5.92 long, 4.52 wide, with ten tergites. Leg measurements: leg I 8.60 (3.04, 2.77, 1.75, 1.04), leg II 8.63 (2.68, 3.16, 1.65, 1.14), leg III 9.80 (2.98, 3.14, 2.28, 1.48), leg IV 14.34 (3.93, 4.47, 3.83, 2.11).
Vulva (Fig.
5
): Poreplate with four notobvious protuberances (two anterolateral and two posterolateral), two posterolateral protuberances not attached to ventral rim of poreplate. Central dorsal opening globular, receptacular cluster grape-shaped. Bulging margins on ventral poreplate only extending to the posterolateral corner of poreplate (Fig.
5
B) and distance between bulging margins almost as wide as poreplate. Genital atrium straight. Posterior area of posterior stalk located in the same plane of poreplate and almost as wide as poreplate (Fig.
5
A).
Diagnosis
Males of the new species resemble
Liphistius nabang
Yu, Zhang & Zhang, 2021 by the general shape of the embolus and tegulum with a clearly outlined distal edge (Fig.
3
) and similar body colouration (Fig.
7
) and the female with a similar-shaped poreplate plate. However,
L. liz
sp. nov. can be distinguished by the male with curved subtegulum (Fig.
2
) [vs. subtegulum straight in
L. nabang
(see
Yu et al. (2021)
, figs. 3A and B)] and tibial apophysis almost as high as wide (Fig.
4
) [vs. wider than high in
L. nabang
(see
Yu et al. (2021)
, figs. 3 D-F)]. Females of the new species can be distinguished from those of
L. nabang
by the straight genital atrium (Figs
5
,
6
) [vs. genital atrium curved in
L. nabang
(see
Yu et al. (2021)
, fig. 4)], posterior stalk and poreplate are located in the same plane (Figs
5
,
6
) [vs. posterior stalk perpendicular to poreplate in
L. nabang
(see
Yu et al. (2021)
, fig. 4)] and posterior stalk two times longer than wide [vs. posterior stalk four times longer than wide in
L. nabang
(see
Yu et al. (2021)
, fig. 4)].
Etymology
The specific name refers to the short name for the Laboratory of Invertebrate Zoology (LIZ), Institute of Zoology, Chinese Academy of Sciences in Beijing; noun in apposition. LIZ was founded by Shen Jia-Rui (see
Dai (1997)
) in 1928, later led by Daxiang Song (see
Marusik (2008)
) from 1975 to 1995 and has been led by the senior author Shuqiang Li from 1995 to the present.
