Etymology
. The specific epithet is derived from the generic name of the host and is a noun in apposition.
Hosts and distribution
.
Ixobrychus
exilis
(
Pelecaniformes
:
Ardeidae
) from
USA
(Michigan) (present paper).
Differential diagnosis
. Among species of the group
herodius
this new species is closest to
H. botaurus
Bochkov and Galloway, 2013
. In females of both these species, femur I has three adjoined ventral setae. These species differ from each other by the following character states. In females of
H. ixobrychus
sp. nov
.
, the cuticular area bearing setae
3a
and pocket-like vulvar structure is smooth (vs. striated in
H. botaurus
), setae
h1
and
h2
are short, shorter than 10 (vs. about 35 long), trochanters I and II bear a single seta each (vs. three setae), palpal seta
dF
is 1.8 times longer than
l”G
(vs. subequal).
