Pulaeus maslovi
sp. nov.
Female
(
Figs. 10–18
).
Gnathosoma
(
Figs. 10–12
). The chaetotaxy of the subcapitulum (
Fig. 10
) is the same as in
P
.
leonidi
sp. nov.
Ventral surface of the subcapitulum in the area of setae
hg4
with transverse rows of lobes which laterally and anteriorly replaced by papillae reaching nearly to setae
hg2
. Anteriad to
hg3
a few longitudinal weak striae are present and oriented towards
hg2
. Dorsal surface of coxal region papillated. Dorsal surface of the first and proximal two thirds of second segment of chelicerae with papillae (
Fig. 11
). Cheliceral seta present. Surface of palps almost smooth except proximal dorsal half of second segment covered by papillae (
Fig. 12
). The chaetotaxy of palps as in
P
.
leonidi
sp. nov.
Idiosomal dorsum
(
Fig. 13
). The chaetotaxy as in
P
.
leonidi
sp. nov.
Entire surface of dorsal idiosomal shield bearing transverse rows of lobes. Setae
f1
and
f2
on each side are situated on sclerotized common platelet without lobes and with distinct borders. Setae
h1
and
h2
are situated on different sclerotized platelets. The length of each simple seta on shield is shorter than distance between its base to base of the nearest seta. Setae
ve
,
f1
and
h1
are the longest among simple dorsal idiosomal setae. Their length is about 1.3-1.7 times longer than
sci
,
c1-2
,
d1
,
e1
and
h2
which are subequal. Setae
f1
is about 1.7-1.8 times longer than
f2
. Dorsal cuticle with clear, long and smooth striae, except small papillated area anterior to anal opening between setae
h1
.
Idiosomal venter
(
Fig. 14
). The borders of coxal plates are distinct (
Fig. 5
). The propodosomal coxal plates are medially completely divided. Each coxal plate with 6 setae. A peg-like seta on the dorsal part of coxae I present. Genital valves with longitudinal rows of lobes. Genital setae (
g1–4
) subequal in length. Setae
g3
situated slightly laterally to row of setae
g1–2
and
g4
. The genital papillae are well-developed. Venter with 5 pairs of setae between hysterogastral coxal plates (excepting setae on coxal plates and genital valves). Integumental striae smooth, except small areas posterior and anterior to genital opening with numerous papillae.

Etymology.
The new species is named after specialist in algology, Dr Ivan Maslov (Nikita Botanical Gardens- National Scientific Center).
Differential diagnosis.
This new species closely resembles
P
.
glebulentus
Den Heyer, 1980
but it differs from the latter by subequal solenidia on the tibia of legs I (the distal solenidion noticeably shorter than proximal one in
P
.
glebulentus
). Also, the area of striation with papillae on the idiosomal dorsum of the new species is much smaller than in
P
.
glebulentus
.
