Eow, Li-Xin, 2014, Australian species of spore-feeding Thysanoptera in the genera Carientothrips and Nesothrips (Thysanoptera: Idolothripinae), Zootaxa 3821 (2), pp. 193-221 : 217

Nesothrips coorongi sp.n.

( Figs 50 , 62 )

Female microptera. Body and legs uniformly brown; antennal segments brown except pedicel of III yellow; major setae pale.

Head wider than long, not projecting in front of eyes, cheeks convex, vertex weakly reticulate, ocelli small ( Fig. 50 ); postocellar setae blunt, posterior to inner margin of posterior ocelli; postocular setae blunt; mid-dorsal setae well-developed, blunt; compound eyes slightly smaller ventrally than dorsally; maxillary stylets wide Vshaped, retracted to postocular setae; maxillary palp segment I as long as wide, segment II about 5 times as long as I, without transverse lines, terminal sensorium setaceous. Antennal segment VIII not constricted at base.

Pronotum transverse, weakly reticulate near margins, notopleural sutures complete, with 5 pairs of blunt major setae ( Fig. 62 ); mesopresternum transverse, boat-shaped; metathoracic sternopleural sutures absent. Meso- and metanotum transverse, reticulate. Fore wing lobe small, bearing 1 or 2 setae.

Pelta broadly triangular, extending about 80% across anterior border of tergite II, reticulate, campaniform sensilla present ( Fig. 62 ); tergites III–VII each with wing-retaining setae minute; tergite IX setae S1 and S2 blunt, shorter than tube, S3 finely acute; tube shorter than head.

Measurements (holotype female in microns). Body length 2750. Head, length 330; width 250; postocellar setae 35; po setae 70; mid-dorsal setae 45. Pronotum, length 175; width 360; major setae am 35, aa 60, ml 75, epim 90, pa 75. Fore wing lobe 65. Tergite IX setae S1 210, S2 210, S3 210. Tube length 260. Antennal segments III–VIII length 110, 110, 100, 80, 60, 25.

Male microptera. Similar to female except smaller, fore tarsus with sharp tooth; head length 300; tergite IX setae 130, 160, 190; tube 215.

Specimens studied. Holotype female. Australia, South Australia, Meningie Airport , from Apodesmia , 15.i.2002. (LAM4103).

Paratypes: 3 females, 1 male taken with holotype.

Comments. This species has a longer head and a wider, non-lobed pelta than other members of this genus related to propinquus and minor . The head and postocellar setae resemble some species of the genus Carientothrips , but the maxillary palps and the widely spaced, V-shaped, maxillary stylets are typical of Nesothrips .
