Diagnosis
According to
Chopard (1929)
, the male
P. obscura
can be distinguished from the other male
Polyphaga
species
by its blackish but dull colour. The female is intermediate in size between
P. aegyptiaca
and
P. saussurei
.
Redescription
Female.
Body length:
30.7–33.5 mm
, body width (measured at the widest point):
22.5– 24.6 mm
. Body generally unicoloured, dark brown (

). Head round, dark brown. Vertex concealed. Eyes small, wide apart; ocelli reduced into two white spots; antennae short; anteclypeus and basal part of labrum white. Pronotum dark brown, arched, apex protruded, anterior margin white, gradually narrowing laterally; anterolateral margins of pronotum with long brown hair (
Figure

Remarks
This
species is poorly known in
China
. Previously, only
Huang et al. (1996)
recorded and described the females and nymphs from
Xinjiang
.
We
did not find the male in
China
, but recorded
three females
and two nymphs from
Kashgar
,
Xinjiang
, one of its
type
localities
.
