Diagnosis
The male of this species differs from that of its congener by (1) the tip of RTA bent at a different angle (see
Figure 4
(a,c)), (2) straight, spine-like and longer process of tegular apophysis (
Tp
) located prolaterally (vs claw-like, shorter and located anteriorly), and (3) having teeth (
Tt
) on the anterior edge of the tegular apophysis (vs no teeth). The female of
S. denisi
differs from that of its congener by (1) the shorter anterior hood and subparallel margins of fovea (vs wider hood and posteriorly converging lateral margins of fovea; see
Figure 5
(a–d)), (2) relatively shorter base of septum and (3) smaller head of receptacle (see
Figure 5
(a–d)).

(c, d). (a, c) male palp, retrolateral view; (b, d) intact epigyne, ventral view. Scale bars = 0.2 mm.
Epigyne as in
Figures 4

); receptacles separated by about 7 diameters and each bearing a small head (
Rh
).
Distribution
Known only from
Dushanbe
and
Khatlon
regions, western to south-central
Tajikistan
(
Figure 6
).
Ovtsharenko and Fet (1980)
and
Krivokhatsky and Fet (1981)
reported this species from
Turkmenistan
, although these records were later attributed to
Parazodarion raddei
(Simon, 1889)
(sub
Zodarion
) by
Mikhailov and Fet (1994)
.
