Differential diagnosis.
Meitingsunes chalcophaps
sp. nov.
is morphologically similar to
M. zenadourae
(
Clark, 1964
) described from
Zenaida macroura
(Columbidae)
in the
USA
. In females of both species, each lateral branch has six chambers; all coxal fields are apunctate, and bases of setae
3a
are situated off coxal fields III. This new species differs from
M
.
zenadourae
by the following features: in females of
M
.
chalcophaps
, the propodonotal shield is divided into two triangular sclerites, bases of setae
ve
,
si
, and
se
are situated off the propodonotal shield; the hysteronotal shield is reduced to a single, triangular sclerite, bearing bases of setae
d1
; the pygidial shield is punctate near bases of setae
f2
and
f1
. In females of
M
.
zenadourae
, the propodonotal shield is entire and rectangular in shape, bearing bases of setae
ve
,
si
and
se
; the hysteronotal shield is divided into three sclerites—two lateral, oval sclerites surrounding bases of setae
d2
and an unpaired rectangular sclerite situated between bases of setae
d1
; central part of the pygidial shield is punctate.
Etymology.
The name "
chalcophaps
" is taken from the generic name of the host.
