Type
material.
Holotype
female from
Agama sankaranica
(ZMUC R36473) [dorsal surface]
NIGERIA
: Ondo State, Idanre;
18–21 August 1958
, coll. Schiøtz and Volsøe.
Type
material deposition.
Holotype
is deposited in the ZMUC (ZMUC–R36473).
Etymology.
This new species is dedicated to the mythological Maasai God of the Sun.
Differential diagnosis:
P. olape
sp. nov.
is similar to
P. engai
sp. nov
.
In females of both species, the cheliceral shaft is 1.3 longer than the base, setae
n
,
dF
, and
dG
are subequal in the length, the free peritremal branches are present and are approximately the same length, the eyes are absent, ventro-median setae
vm1
are filiform, setae
ps
are paddle-shaped with spicules on the apical margin. This new species differs from
P. engai
by the presence of the hypostome with a smooth rounded apex, there are 16 pairs of the peripheral setae inserted ventrally, the genital series is represented by one pair of setae
g
situated ventrally, the pseudoanal series is represented by four pairs of setae
ps
situated ventrally and terminally. In females of
P. engai
,
small denticles at the hypostomal apex are present, the peripheral setae are absent, the genital series is represented by three pairs of setae
g
situated dorsally, the pseudoanal setal series is represented by three pairs of setae
ps
and all of them are situated dorsally.
