Chelicera
. Fixed digit 26 (25–26) long, with four teeth plus the apical one: three teeth between the apical tooth and
pilus dentilis
and one tooth posterior to the
pilus dentilis
. Movable digit, 25 (24–26) long, with one tooth.
Legs.
Genu II with seven setae, 2 2/0 2/0 1; leg IV with three macrosetae:
SgeIV
22 (knobbed),
StiIV
24 (point- ed),
StIV
48 (45–50) (knobbed).
Insemination apparatus
.
Major duct cylindrical, short (7–9). Atrium differentiated, bulbous, embolus visible. Minor duct visible. Calyx bell-shaped, 10 long and 8 wide. The first 1/3 of the calyx is membranous, with in some specimens a small neck between the calyx and the atrium. The remaining 2/3 of the calyx with sclerotised walls.
Remarks.
This is the first time this species is reported from
France
. Specimens reported from the Canary Islands,
Morocco
and
Greece
were collected on the same plant hosts—
Tamarix
sp.—as were the specimens from the present survey.
