Hindsiothrips sisakhti Minaei n. sp.

Female aptera. Body and legs typically pale-yellow, usually with brown markings medially on tergites II–VIII; antennal segments IV–VIII and abdominal tergites II–IX pale-brown, tube brown; all major setae pale. Antennae 8 - segmented, III with 1 outer sensorium, IV with 3 sensoria (2 outer and 1 inner), VIII weakly constricted at base ( Fig. 3 View FIGURES 1 – 7 ). Head as wide as long ( Fig. 8 View FIGURES 8 – 12 ); mouth cone rounded maxillary palps 2 -segmented; maxillary stylets less than one third of head width apart medially, retracted to compound eyes, maxillary bridge not developed ( Fig. 8 View FIGURES 8 – 12 ); ocelli not or only weakly developed, sometimes with two ocelli, compound eyes each with less than 10 facets; postocular setae pointed or bluntly pointed. Pronotum with 5 pairs of major setae: am, aa, ml, epim, and pa ( Fig. 8 View FIGURES 8 – 12 ); all pointed but posteroangular sometimes blunt; prontotal epimeral sutures complete ( Fig. 8 View FIGURES 8 – 12 ), fore tarsi with small tooth ( Fig. 16 View FIGURES 16 – 18 ). Prosternal basantra developed, ferna broader than long ( Fig. 15 View FIGURES 13 – 15 ). Mesonotum weakly sculptured, four small and acute posterior setae; metanotum without sculpture, median setae acute. Pelta rounded apically, weakly sculptured, with one pair of campaniform sensilla (Fig. 22); abdominal tergites without sigmoid setae, III–VIII without sculpture, setae S 1 and S 2 pointed (Fig. 24), sometimes S 1 on VIII blunt; tergite IX setae acute, S 1 smaller than S 2 and S 3 and about 0.8 as long as tube (Fig. 25).

Measurements (holotype female in microns). Body length 1386. Head, length 157; maximum width 155; postocular setae 35. Pronotum, length 127; median width 190; major setae am 29, aa 21, ml 30, epim, 34, pa 30. Pelta length 51, median width 86, tergite III, median discal setae 18; major marginal setae 32. Tergite IX setae S 1 61; 86; 106. Tube length 85; dorsal anal setae 117. Antennal segments III–VIII length 36, 40, 40, 42, 42, 33. Male aptera. Color and sculpture (also size of fore tarsal tooth) similar to female. tergite IX S 2 short and stout (Fig. 26). Sternites without pore plates.

Measurements (paratype male in microns). Body length 1275. Head, length 146; maximum width 142; postocular setae 38. Pronotum, length 125; median width 190; major setae am 26, aa 30, ml 25, epim, 43, pa 33. Pelta length 49, median width 80, tergite III, median discal setae 17; major marginal setae 32. Tergite IX setae S 1 61, S 2 23, 85. Tube length 76; dorsal anal setae 140. Antennal segments III–VIII length 34, 39, 37, 36, 35, 28.

Material studied. Holotype female, IRAN, Kohgiluyeh and Boyer-Ahmad, Sisakht, from foliage leaf under Quercus sp., 29.viii. 2008 (Moslem Behmanesh). Paratypes: 4 females, 7 males taken with holotype.

Comments. The presence of only one sensorium on antennal segment III in this new species also occurs in the type species of the genus, H. pullatus , but the later is dark brown in contrast to the new species which is almost pale-yellow. Morover, in H. pullatus , pronotal epimeral sutures are incomplete (c.f. Fig. 13 View FIGURES 13 – 15 ) (complete in the new species) and pelta nearly rectangular (rounded in the new species). In addition to the difference in number of sensoria on antennal segment III, postocular setae are pointed or bluntly pointed in H. sisakhti whereas these are capitate in the European species in this genus.

Etymology. Sisakht is the capital of Dena County, Kohgiluyeh and Boyer-Ahmad Province, Iran. The city is located on the foothills of Zagros Mountains, 34 km from Yasuj, in the northern part of the Province.
