Etymology.
The specific name is taken from the
type
locality, Yaan City; adjective.
Remarks.
We examined a large sample (
23 males
and
41 females
) from the same rock in Longcanggou National Nature Reserve of
Sichuan Province
. The females are identical to the
paratype
females of
S. longiducta
as described by
Zhang
et al.
(2015)
and are therefore transferred to
S. yaanensis
sp. nov.
Diagnosis.
This new species resembles
S. ovalis
sp. nov.
(
Figs 43
A–E, 44A–D, 45A–B) in having the distal embolus hook-shaped, vRTA stout, serrated with a pointed tip from ventral view and spermathecae bulging laterally. The male differs from
S. ovalis
by: Embolic tip as long as embolic apophysis (distinctly shorter in
S. ovalis
) (
Figs 43
A–C, 44A–D). The female is differentiated from
S. ovalis
by the swollen ends of the glandular appendages (slightly narrower in
S. ovalis
).

I 2026
, II–IV 2326; Mt: I–II 1014,
III 2026
, IV 3136. Measurements of palp and legs: Palp 12.9 (4.4, 1.9, 2.7, –, 3.9); I 39.6 (10.2, 3.4, 11.9, 12.6, 3.6); II 42.8 (11.3, 3.4, 11.9, 12.6, 3.6); III 33.0 (9.1, 3.0, 9.1, 8.9, 2.9); IV 37.0 (10.1, 3.0, 9.8, 10.5, 3.6). Leg formula: II-I-IV-III. Cheliceral furrow with 3 anterior, 4 posterior teeth and ca. 28 denticles.
Palp as in diagnosis. Cymbium distinctly longer than tibia. Embolus arising from tegulum at 6 to 7-o’clock-position in ventral view. Embolic apophysis curved perpendicularly in verntral view, with leaf-shaped end. Tegulum covering parts of proximal embolus. Spermophor curved in ventral view. RTA relatively small, arising distally to medially from tibia. Both dRTA and vRTA with blunt ends, dRTA slightly longer than vRTA (
Figs 56
A–C, 57A–D).
Colouration in ethanol. Dorsal prosoma yellowish-brown, with yellow posterior submarginal transversal light band continuing anteriorly as narrow light submarginal bands along lateral sides between dark margins and broad dark longitudinal bands. Labium and gnathocoxae yellowish-brown, both with distal parts lighter. Sternum yellowish-brown. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots. Dorsal opisthosoma dark brown, covered by grey hairs with light longitudinal heart patch. Ventral opisthosoma yellowish-brown to reddish-brown, with irregular pattern (
Figs 57
E–F).
Redescription. Female:
lateral lobes fused, with eight fusion bubbles along median line. Internal ducts running parallel along the median line, diverging strongly posteriorly (
Figs 58
A–B). Further details and measurements see

et al
