Type material.
Holotype
♂ (SYNU-647), China: Yunnan Prov., Lushui City, Pianma Town, 3.03.2011, Z. Li & L. Wang leg.;
Paratypes
: 2 ♀ (SYNU-648-649), 3 ♂ (SYNU-650-652), same data as for the holotype.
Diagnosis.
The new species can be distinguished from congeners by the blunt end of the cymbiobulb (arrow in Fig.
5F
) vs. lacking a blunt end (see
Tong and Li 2020
: figs 2A, 6A), triangular extension of the dorsal lobe of the embolar region (
'te'
in Fig.
5F
) vs. lacking a triangular extension (see
Tong and Li 2020
: figs 2E, 6H), and absence of a posterior receptacle (Fig.
6H
) vs. with a narrow posterior receptacle (see
Tong and Li 2020
: fig. 4G).

Description.
Male
(holotype). Habitus as in Fig.
4A, B, C
. Body length 2.31; carapace 1.09 long, 0.81 wide; abdomen 1.11 long, 0.87 wide. Body yellow-brown, legs yellow. Carapace (Fig.
4D, F
): oval in dorsal view, without any pattern; pars cephalica slightly elevated in lateral view, surface of pars cephalica smooth; lateral margin straight, rebordered, with small blunt denticles. Eyes (Fig.
4D, F
): ALE largest, PME, PLE subequal; ALE separated by nearly more than their radius, ALE-PLE separated by less than ALE radius, PME touching each other; posterior row recurved from above, procurved from front. Clypeus (Fig.
4F
): ALE separated from edge of carapace by 2 diameters. Mouthparts (Fig.
4E-H
): chelicerae straight, anterior face strongly swollen, with cone-shaped protuberance in lateral view; labium rectangular, anterior margin deeply incised; endites with distal excavation. Sternum (Fig.
4E
): with radial furrows between coxae, surface smooth, covered with large, round pits; setae sparse, dark, needlelike, evenly scattered. Abdomen (Fig.
4A-C
): booklung covers brown; sperm pore small, oval, rebordered, situated between anterior and posterior spiracles; dorsal scutum strongly sclerotized, covering whole abdomen; postgastric scutum strongly sclerotized, covering nearly full length of abdomen, with posteriorly-directed lateral apodemes. Palp (Figs
4I-K
,
5A-G
): pale orange; femur 0.26 long, patella 0.16 long, tibia 0.13 long, cymbiobulb 0.41 long, 0.22 wide, length/maximal width = 1.86; embolar region with flat dorsal lobe (dl), small posterior one (pl), and narrow, leaf-like, wrinkled ventral one (vl), with brush-like structures (bls) in retrolateral view.
Female.
As in male except as noted. Habitus as in Fig.
6A, B
. Body length 2.51; carapace 1.16 long, 0.92 wide; abdomen 1.38 long, 1.12 wide. Epigastric area (Fig.
6F, G
):
'atrium'
relatively wide, broadly oval. Endogyne (Fig.
6H
): with a T-shaped sclerite (tsc) anteriorly, very thin, long and tube-like structure (tls) can be seen inside T-shaped sclerite; with horseshoe-shaped sclerite (hss) medially; apodemes (ap) well developed.
