Pulaeus semistriatus
sp. nov.

Gnathosoma

leonidi
sp. nov.
Ventral surface of the subcapitulum (
Fig. 19
) generally smooth except area around setae
hg4
with papillae (laterally) and with poorly developed striae (between). Also, an area with papillae present on dorsal surface of the coxal region. Entire dorsal surface of the first and proximal tierce of second segments of chelicerae with papillae (
Fig. 20
). Surface of palps almost smooth, except small area in proximal part of second segment with papillae (
Fig. 21
). The ventral seta on second palpal segment is the longest.
Idiosomal dorsum
(

). The chaetotaxy as in
P

leonidi
sp. nov.
Dorsal shield strongly sclerotized with clearly demarcated borders. Anterior part of the shield is smooth. Posterior part with transverse lobes reaching to setae
d
in center and sometimes up to
sce
along the edges of the shield. Dorsal setae relatively long. Setae
c1-2
,
d1
and

subequal and longer than distance

and
f2
situated on common weakly sclerotized platelet,

out of platelet. The integumental striations smooth but small preanal area with papillae.
Idiosomal venter
(
Fig. 23
). The propodogastral coxae are medially completely divided. A small median platelet between the posteromedian edges of coxae II present. Each coxal plate with 6 setae. A peg-like seta on the dorsal part of coxae I present. Integumental striae smooth, except small areas anterior to genital opening with papillae. Genital valves with longitudinal striae. Genital setae (
g1–4
) subequal in length and situated in the same row. Venter with 5 pairs of setae between hysterogastral coxal plates (excepting setae on coxal plates and genital valves).

Etymology.
The name of new species refers to the peculiar surface of the dorsal idiosomal shield.
Differential diagnosis.
This new species differs from other species of
Pulaeus
by the peculiar surface of the dorsal idiosomal shield which is smooth in the anterior and lobed in the posterior part.
