R e d e s c r i p t i o n. Fe m a l e. Dorsal shield (

) well sclerotized, oval-ovate, with shallow lateral emarginations, smooth, with a dark border along the edge; solenostomes 7 pairs (

). Dorsal setae PM3 and PM4 longest, thickened, slightly serrated; AM1 and AL3 are noticeably shorter of them, the rest are even shorter and aligned in length, and smooth. All dorsal setae shorter than distance to the next setae in the row. Seta AL1 half as long the distance to the theca of seta AL2. Setae PL1–PL3 equal in length. Peritreme extend beyond the theca of seta AD1. Genital shield narrower than ventrianal shield, elongated and pentagonal (
fig. 7
,
2
), with almost parallel or slightly concave lateral margins; anal pores large, not shift to each other, slit-like, surrounded by cuticular ridge, which visually makes them larger. Metapodal shields distinct, narrow anterior one about half as long as larger posterior one (
fig. 7
,
3
). The posterior part of the peritremal shield from the stigma at first some narrows, then sharply widens caudally and ends in a coracoid (
fig. 7
,
4
). Chelicera has to 7 teeth on Df, and 1 on Dm (
fig. 7
,

). The funnel of the spermatheca is goblet; atrium sessile (

,

). Leg IV with 3 large macrosetae: longest on basitarsus, shortest on tibia (
fig. 7,

). Genu III with short macrosetа.

Male. Ventrianal shield with 3 pairs of preanal setae, sometimes with one or both setae of an additional pair; anal pores large (
fig. 7
,

). The spermatodactyl L-shaped, with a funnel-shaped extension at the end (
fig. 7
,

). Lds 326.
Diagnosis. The species
T. montanus
is similar to
T. volgini
, from which it differs in the longer dorsal setae AD2, AM2, AD3, AD4, PD1 (9–16 μm), while in
T. volgini
their length is 5–8 μm; seta AL1 shorter than AL3 (on the contrary, in
T. volgini
AL
3 longer than AL1); in
T. montanus
, seta PM1 somewhat shorter than PL3 (respectively, 18 and 22 μm), while in
T. volgini
they are equal in length (both 10 μm); setae PL1, PL2, PL
3 in
T.montanus
of equal length (possible difference is no more than 1 μm), while in
T. volgini
their length is 23, 12, 10 μm; chelicera of
T. montanus
with 1 tooth on Dm,
T. volgini
with 3.

Notes. 1. Description, measurements and illustrations are based on
non-type specimens
from the
Transcarpathian Region
after comparing them with the
type
material of this species
.
2. The text of the original description indicates that the number of pairs of the “small slit-like organs” (= dorsal solenostomes) is 5 (p. 235, first line from the top), whereas actually there are seven pairs of them.
