Gnathosoma
. Chelicerae 210–230 long. Slender cheliceral part 1.7 times longer than swollen cheliceral part. Fixed cheliceral digit with several tines. Setae
dF
1.2 times shorter than

Idiosoma
530–635 long and 1160–1230 wide. Dorsum with 3 groups of serrate setae: 53–67 pairs of antero-lateral setae; 2 pairs of postero-lateral setae and 2 pairs of dorso-median setae
dm1
and

ps1–ps4
, with minute spicules on apical margin.

Host and distribution.
This species is known only from
Agama agama
from
Kenya
[
Garissa County
] (
Fajfer 2013b
).
Remarks.
In the original description of this species setae
a’
and
a”
of tarsi I are marked incorrectly as eupathidia and
it’
and
it”
of tarsi I as simple setae (
Fajfer 2013b
) whereas the re-examination of
P. garissi
shows that setae
a’
and
a
” are simple, and setae
it’
and
it
” of tarsi I are represented by eupathidia.
