Etymology.

refers to the generic name of the host.
Differential diagnosis.
This new species is morphologically similar to
A. prunellae
. In females of both species, aggenital setae
ag1
and
ag2
are subequal in the length and setae
c1
are longer than
se
. This new species differs from
A. prunellae
by the following characters: in females of
A. anthus
, the propodonotal shield is punctate on whole surface; the lengths of setae
f2
and
ag1
are 40 and 55 respectively; the length ratios of setae
c1
:
se
,
tc’III– IV
:
tc”III–IV
and
f2
:
f1
are 1.4:1, 1:2 and 2:1 respectively. In females of
A. prunellae
, the propodonotal shield is without punctations; the lengths of setae
f2
and
ag1
are 60–70 and 70–80 respectively; the length ratios of setae
c1
:
se
,
tc’III–IV
:
tc”III–IV
and
f2
:
f1
are 1.2:1, 1:1.6–1.7 and 3:1 respectively.
