Diagnosis.
The female of
P. julyae
is similar to
P. saopaulo
Carico, 2005
(see Carico 2005: fig. 32) and
P. wygodzinskyi
(Soares & Camargo, 1948)
(see
Silva
et al
. 2006
: fig. 19) by the projected shape of the scape of the middle field of epigynum, but can be distinguished by the longer and triangular shape of the scape and the excavated lateral lobes (LL) (
Figs 4
,
6
).
