Etymology.
The specific epithet is a Latin adjective, referring to the pale coloration of both sexes of this species.
Diagnosis.
This species is most similar to
T
.
alamto
from western
Iran
, from which it differs by the angled anterior edge of the conductor (
vs
. roundly bent), the bulb (from posterior edge to embolus) being longer than it is wide (
vs
. as long as wide), the embolus base positioned at 8:30 o’clock (
vs
. 9:30), the roundly bent embolus (
vs
. the embolus bent at right angle), the relatively long conductor (cf.
Fig. 2A and 2C
), and the converging receptacles forming a right angle (
vs
. obtuse; cf.
Fig. 3B
and
Zamani
et al
. 2018
: fig. 11).
