Lupaeus valentinae
sp. nov.
Female
(
Figs. 44–52
).
Gnathosoma
(
Figs. 44–46
). The length of subcapitulum is shorter than its width. Subcapitulum bearing a peg-like setae on each dorsal edge lateral to the cheliceral trochanters, two pairs of short adoral setae and 4 pairs of simple
hg
-setae of which
hg3
are the longest. The main part of ventral surface of subcapitulum papillated and with transverse rows of lobes near setae
hg4
(
Fig. 44
). The papillae become smaller anteriad and reach to setae
hg2
. The surface of coxal part of the subcapitulum smooth dorsally. The first palpal segment papillated. The surface of second segment smooth except proximal one third part with papillae. The first palpal segment without setae; the second segment with 6 simple setae; the third segment (tibiotarsus) with 5 hair-like setae, 1 bladder-like seta and three-pointed process (
Fig. 45
). The dorsal surface of first and second segments of chelicerae with papillae (
Fig. 46
). The papillae reach across the half of length of second segment.
Idiosomal dorsum
(
Fig. 47
). The surface of dorsal idiosomal shield smooth. The shield with 2 pairs of coarsely setose sensillae (
vi
and
sce
) and 6 pairs of simple setae (
ve
,
sci
,
c1-2
,
d1
and
e1
). Setae
ve
are the longest among simple setae on the shield. Its length is about 1.5 times longer than length of others. Setae
f1
and
f2
on each side are situated on a poorly sclerotized common platelet bearing lobes and with indistinct borders. Setae
f1
is about 1.5 times longer than
f2
. Dorsal cuticle with long and thin striae which bear numerous small papillae posteriad to setae
d1
.
Idiosomal venter
(
Fig. 48
). The propodosomal coxal plates medially completely divided and without small median platelet between the posteromedian edges. Each coxal plate with 6 setae. A peg-like seta on the dorsal part of coxae I present. Genital valves with longitudinal rows of papillae and/or lobes of various length. Genital setae (
g1–4
) subequal in length. Setae
g3
situated more laterally to row of setae
g1–2
and
g4
. The genital papillae welldeveloped; the anterior pair slightly larger than posterior. Venter with 5 pairs of setae between hysterogastral coxal plates (excepting setae on coxal plates and genital valves).

Etymology.
The new species is named after my mother,
Valentina Sergeyenko.
Differential diagnosis.
This new species closely resembles
L. platygnathos
(
Bu & Li, 1991
)
but it differs by the number of solenidia on leg genua
I and IV 4—2
(vs. 3—
1 in
L. platygnathos
). In new species, setae
g3
situated more laterally to row of setae
g1–2
and
g4
(setae
g1–4
situated in the common row in
L. platygnathos
).
