Etymology.
The name
idunae
refers to the generic name of the host.
Differential diagnosis.
This new species is closely related to
S. sturni
. In females of both species, the hypostomal apex is ornamented by 1 pair of the protuberances and the hysteronotal shield is present.
S.idunae
differs from
S. sturni
by the following characters: in females of
S. idunae
, the lengths of setae
vi
and
ve
are 45–55 and 105–110 respectively; setae
ag2
are twice as long as genital setae
g1
; setae
tc’
and
tc”
of legs III and IV are subequal in length. In females of
S. sturni
,
the lengths of setae
vi
and
ve
are 95–105 and 245–275 respectively; setae
ag2
are about 4 times longer than genital setae
g1
; setae
tc”
of legs III and IV 1.5–2 times longer than
tc’III–IV
.
