Intercoxal area between coxae I smooth, between coxae II with transverse striae; area between setae 3a to 4a smooth; area between setae la to 3a and posteriad 4a with broad, transverse striae (Fig. 38); length of setae la 41–61, 1 b 17–22, 1 c 10–16, 2 b 12–17, 2 c 20–24, 3 a 44–60, 3 b 10–16, 4 a 43–56, and 4b 10–15.

Material examined. Two females collected from leaves of apple trees, Malus domestica (L.) (Rosaceae), IRAN: Hamedan Province, Hamedan (34°45ʹN, 48°26ʹE, altitude 2147 m. a. s. l.), 26 September 2008, coll. E. Rostami; 15 females collected from pine trees, Pinus abies (L.) (Pinnacae), IRAN: Hamedan Province, Hamedan (35°48ʹN 48°29ʹE, altitude 1810 m. a. s. l.), 8 November 2008, coll. M. Khanjani; 13 females collected from juniper trees, Juniperus communis (L.) (Cupressacea), same locality, 17 October 2008 - 13 July 2010, coll. M. Khanjani; 2 females collected from walnut trees, Juglans regia (L.) (Juglandaceae), same locality, 12 October-16 November 2008, coll. M. Khanjani; 1 female collected from plum tree Prunus domestica (L.) (Rosaceae) but close to conifer, same locality, 6 November 2008, coll. M. Khanjani. Deposited—CALBS and QMA (2 females).
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.
