Etymology.
The specific name is a patronym in honour of our friend and colleague Anton A. Nadolny (Simferopol,
Ukraine
) who studies
Lycosidae
.
Diagnosis.
The new species is most similar to
S. sibirica
from which it can be distinguished by the tapering tip of the embolus (
Figs 43, 44
), thinner conductor (cf.
Figs 18
,
40, 41
) and the almost rectangular shape of the conductor in posterior view (
Fig. 42
).
Description.
Male. Total length 6.3, carapace 3.25 long, 2.55 wide. Carapace brown without pattern with black area around eyes. Legs brown with annulations. Femur I with 3 dorsal, 2 pro- and 2 retrolateral spines; patella with 2 dorsal, 1 pro- and 1 retrolateral spines; tibia with 2 dorsal, 1 pro-, 1 retrolateral and 5 pairs of ventral spines; metatarsus with 2 pro-, 2 retrolateral and 2 pairs of ventral spines. Leg I segments length: 2.55+1.15+2.7+2.35+1.3. Abdomen brownish grey with indistinct cardiac mark and white spots. Palp as in

Comments
. The species is described in an earlier paper.
Sibirocosa sibirica
has the largest range within the genus and is known from the Putorana Plateau to eastern Yakutia and from Lena River delta to northern Transbaikalia. In Northeastern Siberia it is replaced by
S
.
kolymensis
in the taiga zone and
by
S. subsolana
in the tundra zone.

Sibiricosa
subsolana
has the northernmost range in the genus, occurring from the Kolyma River mouth to the eastern edge of the Chukotka Peninsula and north to Wrangel Island (ca 71°N) (Marusik
et al.
1992). It is possible that the species might also be found in the adjacent Seward Peninsula of Alaska (Marusik
et al.
2004).
