E-mail: m. mirabbalou @ ilam. ac. ir Summary. One of the small genera of the family Aeolothripidae (Thysanoptera: Terebrantia) Rhipidothrips Uzel includes 6 species. Up to now, 4 species of this genus have been recorded in Iran. The wingless morph of R. brunneus Williams is described for the first time based on specimens collected from pasture plants in Javanrud County, Kermanshah Province (western Iran). A key to Iranian species of Rhipidothrips is also provided.	en	Moradi, A., Alizadeh, M., Mirab-balou, M., Pourian, H. R.

Up to the present, four Rhipidothrips species have been recorded from Iran (Mirab-balou, 2018): R. unicolor zur Strassen reported from Canary Islands and Iran (Khuzestan province), R. flavus Tunç from Türkiye and Iran (Golestan and Hamedan provinces), R. gratiosus Uzel from Southern areas of the western Palaearctic, California, Türkiye and Iran (Azarbaijan-e-Sharghi, Fars, Kerman, Golestan, Hamedan provinces), and worldwide R. brunneus Williams.	en	Moradi, A., Alizadeh, M., Mirab-balou, M., Pourian, H.

850335652A7EFFDCBCFF7B53FBD6FDAA.taxon	diagnosis	DIAGNOSIS. FEMALE (f. apterous) Body, legs and antennae largely brown; tarsi, apex of mid and hind tibiae, mostly of for tibiae and base of mid and hind femora yellow (Fig. 1); antennal segments I-II brown, apex of II yellow, III-IV yellow (Fig. 4). Head. Antennae 9 - segmented, segments VII-IX fused, segments III and IV with transverse sense cone at apex. Head with less than five pairs of small ante-ocellar setae; more than 6 thick setae on cheeks, behind compound eyes. Thorax. Pronotum with one pair of long posteroangular setae and 2 pairs of posteromarginal setae. Mesonotum without microtrichia on sculpture lines. Metanotum with elongate reticulations, without microtrichia, median setae near at posterior margin. Fore tarsus with strongly recurved denticle. Abdomen. Abdominal tergites with transverse reticulation, trichobothria on last segment about as large as major setal bases. Abdominal sternites III-VI with 2 or 3 pairs of posteromarginal setae; sternite VII with 4 pairs of posteromarginal setae, 2 pairs of supernumerary setae, 3 discal setae laterally. Ovipositor well developed.	en	Moradi, A., Alizadeh, M., Mirab-balou, M., Pourian, H. R. (2024): WING POLYMORPHISM OF RHIPIDOTHRIPS BRUNNEUS WILLIAMS, 1913 (THYSANOPTERA: AEOLOTHRIPIDAE.

850335652A7EFFDCBCFF7B53FBD6FDAA.taxon	description	FEMALE (f. microptera) (Fig. 2). Similar to apterous morph, with wings lobe shorter than thorax (Fig. 5). FEMALE (f. macroptera) (Fig. 3). Fore wing pale with posterior margin weakly shaded, with cross veins visible (Fig. 6). MALE. Abdominal tergite I with paired longitudinal ridges scarcely one third as long as tergite. Figs 1 – 6. Rhipidothrips brunneus, female: 1 – f. aptera; 2 – f. microptera; 3 – f. macroptera; 4 – antenna; 5 – fore wing lobe of micropterous form; 6 – fore wing of macropterous form.	en	Moradi, A., Alizadeh, M., Mirab-balou, M., Pourian, H.

850335652A7EFFDCBCFF7B53FBD6FDAA.taxon	discussion	REMARKS. Wings may be present or absent in thrips species; and the wings when present are unique among insects because they are narrow, with few or no veins, fringed with long hairs that hence give the order's name. Recently, we collected many thrips specimens on rangeland plants and one of them, R. brunneus was dominant. After the identification of specimens, the wingless form of this species is described for the first time. Because of extensive collecting in both spring and summer, it seems likely that both morphs of the species occur only at the end of spring and early in summer.	en	Moradi, A., Alizadeh, M., Mirab-balou, M., Pourian, H.
