Neohydatothrips barrowi sp.n.

( Figs 37–40 )

Female macroptera. Mainly whitish yellow, with weak pale brown shading on fore coxae, metathoracic epimera, metanotum, and tergites II–VII anterolaterally; antennal segments IV–V weakly shaded at apex, VI–VIII pale brown; forewing pale. Head with occipital carina close to eyes; ocellar triangle transversely striate with no markings between the striae; ocellar setae III within ocellar triangle; three pairs of postocular setae, median pair long; postoccipital region transversely striate; mouth cone unusually long, extending to metasternum. Pronotum with closely spaced transverse lines, blotch not clearly defined. Mesonotum and metanotum with no markings between major sculpture lines, metanotal sculpture mainly linear. Metasternal anterior margin with shallow emargination. Forewing with no setae on second vein; wing apex with no sub-apical lobe. Tergites I–VI medially without marginal microtrichia; only VI with some discal microtrichia medially. Sternites II–VII medially without marginal microtrichia, discal microtrichia not extending mesad of setae S2.

Measurements. Holotype female in microns: Body length 970. Head, length 340; width across eyes 130. Pronotum, length 85; width 165. Forewing length 610. Antennal segments III–VIII length 50, 40, 40, 45, 10, 20.

Material studied. Holotype female, Western Australia, Barrow Island, 1.v.2007 (S. Callan), in ANIC.

Paratypes: 1 female with same data as holotype; 2 females from same locality, v.2005.

Comments. This species is remarkable for its pale colour, and the mouth cone extending beyond the mesothoracic coxae, longer than in any described species of Sericothripinae other than the South African N. smutsi (Faure) . The specimens were extracted from litter and vegetation with no host plant association.
