Diagnosis.
The species is similar to the European species
P. furcata
Simon, 1914
, from which it can be separated by the ventral branch of the tibial apophysis (
Vb
) directed forward (
vs
. directed downward), short prolateral fold (
Pf
) of conductor (
Cn
) and by having a projection (
Pb
) on the base of embolus (
Eb
) (cf.
Figs 22–23, 26
and figs
3–4 in
Di Franco (2001))
.
Comment.
This species was treated in three taxonomic publications and previously known from original figures only.
Description.
Male. Habitus as in
Fig. 29
. Total length 6.2. Carapace: 2.8 long, 2.05 wide. Coloration. Carapace, sternum, labium, maxillae and chelicerae brown. Legs and palps brown, legs III and IV lighter. Abdomen beigegray with brown scutum. Spinnerets gray. Leg spination: I: Fe: d1-1-1, p0-0-1; Ti v0-0-2; Mt v2-0-0. II: Fe d1-1-1, p0-1-1; Ti v0-0-2; Mt v2-0-0. III: Fe d1-1-1, p0-1-1, r0-0-1; Pt r1; Ti d1-0-0, p1-1-1, r1-0-1, v1-1-2; Mt d0-1-0, p0-1-0, r1-0-0, v0-2-0; IV: Fe d1-1-0, p0-0-1, r0-0-2; Ti p2-0-1, r0-0-1, v3-1-2; Mt d0-2-0, p2-1-0, r2-1-0, v3-2-0. Leg measurements. I: 6.41 (1.95, 1.15, 1.4, 1.18, 0.73); II: 6.31 (1.9, 1.1, 1.38, 1.2, 0.73); III: 5.54 (1.8, 0.93, 0.71, 1.35, 0.75); IV: 7.59 (2.1, 1.05, 1.63, 1.98, 0.83).

. Tibial apophysis splits into short, triangular dorsal branch (
Db
) and long, digitiform and straight ventral branch; tegulum ovate, with an indistinct constriction in the middle part; sperm duct (
Sd
) forming one loop; petal-shaped, membranous conductor (
Cn
) envelopes embolus prolaterally; embolus sharply pointed, with a wide square base (
Eb
).
Female. Unknown.
Distribution.
Uzbekistan
and southwestern
Tajikistan
(new record).
Comments.
The new combination is proposed based on the large retrolateral tibial apophysis divided into branches and short apical embolus partly entwined by membranous conductor, which is similar to those known in
Poecilochroa
Westring, 1874
.
