Differential diagnosis
.
Among species devoid of setae
d2
the new species is closest to
Passeroptes inermis
Fain, 1965
from
Calocitta formosa
(Swainson)
(
Passeriformes
:
Corvidae
) (
Fain 1965
). In both sexes of these two species the retrorse processes of femora III and IV are absent or reduced to a very small and indistinct transverse crest on the dorsal surface; the shape of the humeral shields is similar, with bent extensions; coxal apodemes II to IV are free. In males the hysteronotal shield is not transversely divided, the anterior part of the hysteronotal shield is narrower than the lobar part of the shield; in females, setae
se
are short and not extending the anterior margin of the hysteronotal shield, and the adanal shields are well developed and not fused. The new species differs from
P. inermis
by the following features. In both sexes of
P. picae
sp. nov.
, one weakly developed dorsal retrorse process is present on each of genua I and II; in males, setae
se
extend beyond the anterior margin of the hysteronotal shield and the adanal shields are short and wide; in females, setae
se
extend beyond a level halfway between the propodonotal and hysteronotal shields. In both sexes of
P. inermis
, genua I and II are without retrorse processes; in males, setae
se
do not extend beyond the anterior margin of the hysteronotal shield; in females, setae
se
do not extend beyond halfway between the propodonotal and hysteronotal shields.

Remark
.
Specimens of
P. garrulax
and
P. poecilorhynchus
sp. nov.
were collected from the same individual of
Garrulax
poecilorhynchus
berthemyi
(David and Oustalet).
In the original description of
Passeroptes garrulax
Fain, 1965
from
Garrulax leucolopbus bicolor
, which had been imported from
Indonesia
and died in the Antwerp Zoo,
Fain (1965)
stated that the leg setation is as in
P. dermicola
and that tarsi I and II of
P. dermicola
possess setae
ba
. However, in our examined specimens of
P. garrulax
, setae
ba
were absent on tarsi I and II. Furthermore, in two other species,
P. formosus
sp. nov.
and
P. poecilorhynchus
sp. nov.
, collected by us from birds of the genus
Garrulax
, setae
ba
-I, II are also absent.
