Differential diagnosis.
This species belongs to the
crassior
group and is most similar to
P. gratus
by having rod-like thickened basally setae
cG
of genu II and dorsal spine on femur II in heteromorph males. The new species differs from
P. gratus
by the following features. In heteromorph males of
P. pulchellae
, the subcapitulum is crossed by an entire bow-shaped fold going from one postero-lateral angle to another, tibia II has no ventral process, and the dorsal spine of femur II is short and rounded; in females, setae
ps1
are extremely short, filiform and do not exceed the distance between setae
h3
, setae
f2
have no additional spines on their lateral margin, and setae
e2
have a narrow membranous enlargement in their basal half. In heteromorph males of
P. gratus
, the subcapitulum has oblique bow-shaped folds in its postero-lateral angles, tibia II bears a large verrucous ventral tubercle, and the dorsal spine of femur II is acute; in females, setae
ps1
are longer than the distance between setae
h2
and have an additional spine in their basal part, setae
f2
have an additional spine on their lateral margin, and setae
e2
are thick, setiform and have no membranous enlargement.
Etymology.
The specific epithet derives from the specific name of the
type
host and is a noun in the genitive case.
