Description
Male
(Fig.

). PL 6.5, PW 5.8, AW 2.7, OL 7.6, OW 4.0. Eyes: AME 0.29, ALE 0.45, PME 0.33, PLE 0.42, AME-AME 0.24, AME-ALE 0.10, PME-PME 0.51, PME-PLE 0.60, AME-PME 0.50, ALE-PLE 0.52, CH AME 0.15, CH ALE 0.20. Spination: Palp: 131, 101, 2121; Fe: I-III 323, IV 321; Pa: I-IV 000; Ti: I-III 2026, IV 2326; Mt: I-II 1014, III-IV 3036. Measurements of palp and legs: Palp 13.1 (3.7, 2.4, 2.8, -, 4.2), I 35.2 (8.8, 3.2, 9.5, 10.5, 3.2), II 37.5 (9.6, 2.9, 10.5, 11.3, 3.2), III 28.5 (8.1, 2.8, 7.4, 7.7, 2.5), IV 31.0 (8.5, 2.4, 8.1, 9.1, 2.9). Leg formula: II-I-IV-III. Cheliceral furrow with three anterior and four posterior teeth, with 31 denticles. Dorsal prosoma yellowish-brown, with distinct fovea and radial furrows. Chelicerae deep reddish-brown. Sternum reddish to yellowish-brown, with margin brown. Gnathocoxae and labium yellowish-brown, with distal parts lighter. Legs deep yellowish-brown, covered by short spines. Dorsal opisthosoma yellowish-purple, lateral field of opisthosoma with three pairs of black patches. Ventral opisthosoma deep yellowish-brown with irregular patches.
Palp as in diagnosis (Figs
4
,
5
). Cymbium about two times longer than tibia in ventral view. Conductor arising from tegulum in 1-
o'clock-position
. Tegulum median part slightly wider than proximal part. Spermophore slightly curved in ventral view. RTA arising subdistally from tibia, dRTA dorsally digitiform in ventral view and about two times as long as vRTA in retrolateral view.
Female
.
Unknown.
Diagnosis
Males of this new species can be distinguished from all other
Sinopoda
species except
S. angulata
and
S. pyramidalis
(
Zhong et al. 2019
: Figs 50A-C and 51A-D) in having a thin embolus, as long as embolic apophysis, and embolic apohysis distinctly wider than embolus. It can be distinguished from the other two congeners by the following combination of characters: 1) tip of embolus apohysis with blunt ends (pointed ends in
S. angulata
and
S. pyramidalis
); 2) embolus arising from tegulum at 7- to 8-
o'clock
position in ventral view (6-
o'clock
position in
S. angulata
; 8:30- to 9-
o'clock
position in
S. pyramidalis
); 3) dRTA is straight with blunt ends in ventral view (slightly curved, with pointed ends in
S. angulata
; broad, bulging in
S. pyramidalis
) (Figs
1
,
4
).
Etymology
The specific name refers to the type locality; adjective.
Distribution
Known only from the type locality (Fig.
