Type material.
INDIA
:
Holotype
female from
India
, no. 871,
Topal
leg. (
MHNG
,
MHNG0011
).
Etymology
. The specific name is derived from the Latin adjective
bifarius
, -
a
, -
um
, meaning “double, two-fold, dual”, referring to duplicate arrangement of the visible slcerotised parts of the IDS in ventral view; adjective.
Diagnosis.
The female of
P. bifaria
Zhang, Jäger & Liu
,
spec. nov.
is similar to that of
P. albolineata
Jäger, 2001
(Jäger 2001) by having a similarly arranged IDS with visible two pairs of transversally arranged parts in ventral view, but can be distinguished by: 1) Median septum tripartite with two light “windows” and a sclerotised median part; 2) The lateral loops of the IDS extending distinctly beyond the FW (medium septum unstructured and LL extending not that distinctly beyond FW in
P. albolineata
). The female of
P. bifaria
Zhang, Jäger & Liu
,
spec. nov.
is similar to that of
P
.
zixiensis
by having similarly shape of medium septum, but can be distinguished by: 1) Posterior margins of LL with median incision; 2) IDS forming two rows in dorsal view; 3) FW strongly bent (without incision, oval-shaped, with coiling ducts embedded, almost straight in
P
.
zixiensis
).

Epigyne
(
Figs 33A–C
): As in diagnosis. EF wider than long, without obvious AB. Anterior margins of LL forming a ‘V’. FW leading posteriorly to mediad loop, then running laterally and leading to internally structured S.
Colouration
(
Figs 34A–B
): DS reddish brown with dark spots, two lateral bands, margin with thin line and brown pattern. Fovea and striae distinctly marked. OS dorsally with brown marks, with a broad transverse band in posterior half. OS ventrally with brown marks, mainly arranged in median line and on lateral sides.
MALE: Unknown.
