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 S 1 about 0.5 as long as S 2 (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 S 1 50; S 2 75. Tergite X length 75; setae S 1 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 S 2 setae on the eighth tergite are relatively long (Fig. 70), although not as long as in M. tanyoeikus .
