description: Sitothrips izadpanahi sp. n.
Female macroptera. Body generally brown, antennal segment III pale, shaded at margin, IV light brown, all tarsi pale, fore tibia yellow at apex; major setae on pronotum light brown, other setae brown; fore wings shaded.
Antennae 8-segmented; segment I without dorsal apical setae, segments III–IV with forked sense cone; microtrichia present on III–V. Head longer than wide, slightly produced in front of eyes, transversely weakly reticulate (Fig. 2); three pairs of ocellar setae present, ocellar setae III on tangent joining posterior margins of hind ocelli, about three times as long as ocellar setae I and II (Fig. 2); four pairs of postocular setae present, post ocular setae III long, longer than antennal segment II. Eyes without pigmented facets. Maxillary palps 3-segmented (Fig. 5). Pronotum with irregular transverse sculpture lines; two pairs of posteroangular setae, posterior margin with 3–4 pairs of setae (Fig. 4). Ferna meeting medially (Fig. 5). Fore tarsus with a small ventro-apical tubercle (Fig. 3). Metanotal sculpture longitudinally linear on anterior half, median setae near anterior margin, closer to lateral pair than to each other; campaniform sensilla absent. Mesosternum with spinula, metasternum without. Fore wing narrow, first vein with about 10 widely spaced setae, second vein with 7–11; clavus with 5–6 veinal and 1 discal seta. Tarsi 2-segmented. Abdominal tergites with transverse reticulation medially; tergites II–VIII with median setae (S1) small and wide apart but nearly twice as long as setae S2; IV–VII with paired very weak ctenidia laterally terminating just anterolateral to setae S3; tergite VIII with weak paired ctenidia anterolateral to spiracle but also with irregular microtrichia on sculpture lines mesad of the spiracle, posteromarginal comb not developed (Fig. 6); IX with two pairs of campaniform sensilla, tergite X divided. Sternite II with 2 pairs of posteromarginal setae, III–VII with 3 pairs, median pair on VII arising submarginally; discal setae absent.
Measurements (holotype in microns). Body length distended 1715. Head length (width) 167 (133); postocular setae 37. Pronotum length (width) 128 (185); posteroangular setae 56. Fore wing length (median width) [taken from one female paratype] 800 (40). Tergite IX S1 setae 100, S2 setae 120. Antennal segments I–VIII length 26, 34, 42, 40, 36, 45, 9, 13.
Male. Similar to female; abdominal tergite IX with two pairs of stout setae (Fig. 8); sternites III–VII with oval pore plate, smaller on VI and VII (Fig. 7).
Measurements (paratype in microns). Body length distended 1275. Head length (width) 145 (124); postocular setae 30. Pronotum length (width) 106 (154); posteroangular setae 37. Fore wing length (median width) 733 (33). Antennal segments I–VIII length 20, 30, 34, 35, 33, 43, 7, 11.
Specimens examined. Holotype female: IRAN, Fars Province, Shiraz, from leaves of grasses (Poaceae), 25.iv.2014 (KM 1167), in the Natural History Museum, London.
Paratypes: 6 females, 2 males, same data as holotype, in Department of Plant Protection, College of Agriculture, Shiraz University, Shiraz; 1 female paratype in the Natural History Museum, London, and one in the Australian National Insect Collection, Canberra.
Comments. Differing from the other species in Sitothrips by the presence of 3-segmented, rather than 2-segmented, maxillary palps, S. izadpanahi is superficially close to arabicus. They differ in that in arabicus the apex of the fore tarsus bears a curved hook-like projection that appears to be associated with the arolium in the available slide-mounted specimens; this structure is absent in the new species (Fig. 3). Moreover, arabicus has strong sculpture on the head and pronotum but the new species lacks such sculpture (Figs 1, 2, 4).
