Differential diagnosis
. The new species,
Aniacarus ani
sp. n.
is very close to
A. mexicanus
Gaud and Atyeo, 1990
and differs from it by the following features. In both sexes of
A. ani
, the prodorsal shield slightly extends beyond the level of scapular setae
si
(
Figs. 1
A, 2A); in males, the anterior end of the genital apparatus distinctly extends beyond the level of inner tips of epimerites IIIa, setae
e2
are narrowly lanceolate, setae
ps2
are twice as long as setae
f2
(
Fig. 1
B); in females, the width of epigynum is less than the distance between setae
4b
(
Fig 2
B). In both sexes of
A. mexicanus
, the prodorsal shield does not extend beyond the level of scapular setae; in males, the genital apparatus is very short and does not extend to the level of tips of epimerites IIIa, setae
e2
are filiform, setae
f2
and
ps2
are subequal in length; in females, the epigynum is as wide as the distance between setae
4b
.
Etymology
. The specific epithet is taken from the specific name of the host and is a noun in apposition.
