Abdominal sternites with distinct transverse striations; sternite II with 3 pairs of posteromarginal setae, median pair far from posterior margin; III–VI with 4 pairs; VII with 4 pairs of which the last lateral pair is far from posterior margin, the distance of S1 setae from each other usually approximately equals to that of S1from S2 (Figs 26-27); sternites II–VI each with 0-3 median discal setae (in holotype, II–V each with 1seta, and VI with 2 setae); sternite VII with 2 pairs of accessory setae, arranged besides each other, far from posterior margin (Fig. 27-28). In two paratypes sternite VII with 1 or 2 (one seta in each side) discal setae laterally in addition to 2 pairs of accessory setae submedially (Fig. 27). Spermatheca structurally very similar to that of tenuicornis (see: Bhatti 1988), but slightly smaller and thinner, with fewer number of spiniform chitinous processes (Fig. 28).

Legs yellowish brown, fore tibiae yellow, all tarsi yellow. Antennal segments I pale brown; II–IV yellow; III–IV with apical margins light brown; V–IX light brown; V lighter in distal two thirds (Fig. 30). Mesonotum with 1-3 pairs of median setae. Middle coxae with stridulatory structure (Fig. 31). Abdominal tergites IV–VI with dorsal tubercles (Fig. 32). Sternites III with 0-6; IV with 3-6; V with 3-6; VI with 2-7 and VII with 2-5 discal setae. Segment IX with bifurcate claspers, and with sickle-shaped setae laterally (Fig. 33), with dark dorsal plate rounded anteriorly, campaniform sensilla situated out of dorsal dark plate, posterior margin concave medially, semilateral setae short, only slightly surpassing the dorsal furcate claspers, two median setae S1 rather long and curved (Fig. 33).

Measurements (paratype male, in microns). Body distended length 1350. Head length (width across cheeks) 118 (157).

This species is named after the genus of plant from which it was collected.


Possession of discal setae on sternites is not usual in the genus Aeolothrips . This condition can be seen at least in two other aberrant species, the Indian species, Aeolothrips moundi Kulshrestha & Vijay Veer, which has one pair of discal setae laterally on sternite VII in female ( Kulshrestha and Vijay Veer 1984), and the African species Aeolothrips scabiosatibia Moulton, with 2-3 pairs of discal setae laterally on sternites VI–VII in female.

Female of Aeolothrips gundeliae sp. n. is distinguished from Aeolothrips moundi by presence of discal setae on sternites II–VI (0-3) and in the same time there is no discal seta on sternite VII (except two paratypes as explained above). Moreover, they are different in mesonotal median setae (1-2 pairs versus 1 pair) and color of fore wing apex (white versus shaded). Female of Aeolothrips scabiosatibia especially characterized by the spiny fore tibia on dorsal side, and long pronotal posteromarginal seta. Male of the new species is distinguished from Aeolothrips moundi and Aeolothrips scabiosatibia by having claspers and having several discal setae on sternites.

The new species shares some characters with the Australian genus Desmothrips Hood, such as presence of discal setae on sternites as well as presence of more than one pair of mesonotal setae in some specimens. But in Aeolothrips gundeliae sp. n., sternal discal setae III–VI are placed medially (versus laterally in Desmothrips ). Additionally, sternite VII has 2 pairs of accessory setae submedially between marginal setae S1 and S2, whereas in Desmothrips in addition to the marginal setae, sternite VII has discal setae laterally and sometimes medially, as well as 2 pairs of accessory setae submarginally between marginal setae S1 and S2 ( Mound and Marullo 1998, Mound 1972). Finally, apex of fore wing of the new species is not shaded in contrast to Desmothrips species (except Desmothrips marilynae Mound & Marullo, 1998).

Aeolothrips gundeliae sp. n. was collected only on Gundelia tournefortii from various areas of the province. Furthermore, this species was observed in 6 of 10 samplings on this plant; so, it seems likely to be a monophagous species on this plant.
