Diagnosis.
Males of
S. longshan
resemble those of
S. nuda
Liu, Li & Jäger, 2008
(
Liu
et al
. 2008
: figs 5A–D) in lacking an embolic apophysis and the embolus base undulating and broader than its tip, but can be separated by: 1. Palp with tegulum partly covering proximal part of embolus (not in
S. nuda
); 2. Palp with RTA without distinct brush of stiff hairs (conversely in
S. nuda
). Females of this species can be distinguished from other
Sinopoda
species by the unique posterior margin of epigyne, which is distinctly bilobate with sharp indentation (
Figs 39
A–B).
Description. Male:
Measurements: PL 5.8, PW 5.4; AW 2.3; OL 5.9, OW 3.3. Eyes: AME 0.23, ALE 0.36, PME 0.27, PLE 0.40, AME–AME 0.18, AME–ALE 0.06, PME–PME 0.22, PME–PLE 0.43, AME–PME 0.36, ALE–PLE 0.43,
CH
AME 0.25,
CH
ALE 0.30. Spination: Palp: 131, 101, 1021; Fe: I–III 323, IV 331; Pa: I–III 101, IV 000; Ti: I–III 2326,
IV 2226
; Mt: I–II 1014, III–IV 3036. Measurements of palp and legs: Palp 10.1 (3.7, 1.6, 2.3, –, 2.5); I 26.9 (5.4, 3.0, 8.6, 7.6, 2.3); II 29.1 (7.1, 3.2, 9.4, 7.5, 1.9); III 24.0 (5.4, 2.8, 6.7, 6.8, 2.3); IV 27.9 (7.9, 2.7, 7.1, 7.6, 2.6). Leg formula: II-IV-I-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 21 denticles.
Palp as in diagnosis. Cymbium nearly as long as tibia. Embolus arising from tegulum at a 6-o’clock-position in ventral view, with filiform tip. Sperm duct slightly curved in proximal part. RTA arising distally from tibia. Tip of dRTA hook-shaped, vRTA rectangular in ventral view (
Figs 37
A–C, 38A–D).
Colouration in ethanol. Dorsal prosoma pale yellow, with two dark lateral bands with serrated inner and outer margin. Fovea and radial furrows distinctly marked. Median field of prosoma with a reddish-brown median line from fovea to posterior eye row and two small dots in front of the fovea. Labium and gnathocoxae pale yellowish, both with distal parts lighter. Sternum pale yellowish. Chelicerae yellow-brown, with longitudinal bands frontally. Legs pale yellowish with dark spots. Dorsal opisthosoma brown, covered by gray hairs, with three dark spots laterally, in posterior half with dark transversal band above spinnerets. Ventral opisthosoma deep yellowish-brown, without pattern (
Figs 38
E–F).
Redescription. Female:
epigynal field wider than long, with narrow anterior bands and one slit sensillum on each side of the epigynal field. Internal ducts running parallel along the median line, diverging strongly posteriorly. Glandular appendages distinctly narrower than posterior parts of spermathecae. Fertilization ducts arising posteriolaterally (
Figs 39
A–B). Further details and measurements see
Yin
et al
. (2000)
