Stictothrips farsi
sp.n.
Female aptera
(
Fig. 9
). Body yellow with light brown markings and fine complex reticulate sculpture, distal part of tibiae and tarsi yellow, antennal segments II–III light brown, major setae light brown. Antennae 8-segmented, III with one sense cone, IV with two major sense cones, VIII narrowed at base but not constricted (
Fig. 15
). Head longer than wide, post ocular setae capitate, placed laterally on head, not extending beyond hind margin of eye (
Fig. 31
); mouth cone short. Pronotum with 4 pairs of relatively well-developed major setae (anteroangulars, midlaterals, epimerals, and posteroangulars), anteromarginals scarcely longer than discal setae, all pointed except epimeral that is blunt (
Fig. 33
); notopleural sutures complete. Prosternal ferna developed. Fore tarsal tooth developed (
Fig. 31
). Meso and metanotum very weakly sculptured. Metathoracic sternopleural sutures extend posteriorly from the midcoxal cavities. Pelta trapezoidal, with weak sculpture, campaniform sensilla present (
Fig. 40
); abdominal tergites II–VII with one pair of wing-retaining setae; segment IX with seta S1 and S2 pointed, about half as long as the tube; tube short, length less than twice basal width, shorter than head (
Fig. 42
).

Comments.
The shape of head, delicate sculpturing and the sense cone formula on antennal segments III & IV suggest that the new species belongs to
Stictothrips
.
However, the curious short and laterally placed post ocular setae on the head and the paired round pore plates on sternite VIII of the male make this species unique in the genus. It shares some characters with the Australian species
S. aoristus
in the wing reduction and resultant loss of certain character states.
