Philisca doilu
:
Ramírez 2003: 191
.
Diagnosis:
Resembles
P. hyadesi
by the low cephalic area (
Ramírez 1993
: fig. 30), the transversely wrinkled median field of the epigyne advanced from the epigastric furrow (
Fig. 6b
), and the elongate paramedian apophysis (
Fig. 8
). It can be distinguished by the narrower sternum (
Fig. 7c
; width less than 63% of the sternum length).
Description:
Female
: described in
Ramírez (1993)
.

Fig. 8
): Tibia width/length 0.28. Embolus short, anterior margin longitudinally flattened, slightly projecting in a ridge; basal process flattened, rounded (
Fig. 8
). MA long, with one big branch at base (
Fig. 8h
