MALE and immature stages. Unknown.
Remarks.
This species belongs to the
A. macswaini
group and resembles
Pseudoleptus
spp. by having long prodorsal projections. Their pad-like claws, longitudinal striae between coxae III–IV, and simple, smooth setae are also like species of
Pseudoleptus
, although these character states are also found in several species of
Aegyptobia
. All species of
Pseudoleptus
are found on grass and, although
A. persicae
was found on soil, this suggests they may have derived from grasses. However, their fairly broad prodorsal projections, anteriorly-directed palp eupathidia and solenidion, and areolate-rugose sculpturing are unlike any
Pseudoleptus
, which in contrast have simple setae, acute projections, rayed palp eupathidia and solenidion and mostly striate sculpturing. Nevertheless, species like
A. persciae
demonstrate the strong likelihood of a close relationship between the
A. macswaini
species group and
Pseudoleptus
.
