Masamithrips wyndhami sp.n.

(Figs 69–70)

Female macroptera. Body and legs mainly yellow, abdominal segment X brownish yellow; antennal segments I– IV yellow, V weakly shaded near apex (Fig. 69), VI–VIII brown; fore wing pale. Similar to M. melinus in body structure and chaetotaxy; head relatively long, cheeks almost as long as lateral margin of eyes; prosternal basantra with 16 setae; tergite VIII setal pair S1 about 0.5 as long as S2 (Fig. 70); tergite IX with median dorsal setae extending well beyond posterior margin of tergite, stouter than posterior median setae but subequal in length (Fig. 70); tergite X shorter than IX. Sternite II with 7 discal setae and 3 pairs of marginal setae; III–VII with irregular double row of 8–10 discal setae.

Measurements (holotype female in microns). Body length 1350. Head length 105; width across eyes 115; ocellar setae III 15. Pronotum, length 125; maximum width 130; pa inner setae 35; pa outer setae 55. Fore wing length 570. Metanotal median setae 20. Tergite IX length 90; median dorsal setae 55; setae S1 50; S2 75. Tergite X length 75; setae S1 50. Antennal segments III–VIII length 35, 25, 30, 45, 7, 10.

Material studied. Holotype female, Western Australia, Wyndham 30km south, from Triodia sp., 26.ii.2005 (LAM 4619).

Comments. This is a particularly elongate species, with relatively slender antennae, an unusually large number of setae on the prosternal basantra, and three pairs of marginal setae on the second sternite. The S2 setae on the eighth tergite are relatively long (Fig. 70), although not as long as in M. tanyoeikus .
