Material examined

Comparative material
.
Type
specimens of
A. ueckermanni
deposited at Zoology Department of Plant Pests & Diseases Research Institute Evin,
Iran
, Accession number: T-1122., lent from Dr. M. Khosrowshahi.
Remarks
. We examined one
paratype
of
Aegyptobia ueckermanni
(
Khosrowshahi and Arbabi, 1997
)
and found that it exhibits the same dorso-ventral pattern, shape and length of dorso-ventral setae, and leg chaetotaxy as
Aegyptobia tragardhi
Sayed, 1950
. Therefore, we consider
A
.
ueckermanni
syn. nov.
a junior synonym of
A. tragardhi
. One minor difference is that, according to
Sayed (1950)
, the rostrum extends to the distal end of tibia I, but in the Iranian specimens the rostrum extends to the middle of genu I. We consider this difference minor and possibly reflecting a difference in specimen preparation.
