Mound, Laurence A. & Masumoto, Masami, 2009, Australian Thripinae of the Anaphothrips genus-group (Thysanoptera), with three new genera and thirty-three new species, Zootaxa 2042 (1), pp. 1-76 : 46

Anaphothrips nimbus sp. n.

( Figs 117–119 )

Female macroptera. Body and legs light brown, tarsi and tibiae mainly yellow; antennal segments I–II and IV–VIII brown, III paler but with apex shaded; fore wing pale with median brown band. Head wider than long, with transverse lines on posterior third, ocellar region without sculpture ( Fig. 118 ); ocellar setae III anterior to posterior ocelli, just outside triangle; eyes with 6 weakly pigmented facets. Antennae 8-segmented, III–IV with sensorium forked; II–III without microtrichia; VI weakly pedicellate; VIII longer than VII ( Fig. 119 ). Pronotum almost without sculpture. Mesonotum with few transverse lines. Metascutum irregularly reticulate, median setae behind anterior margin; MCS present medially. Fore wing first vein with about 7 setae on basal half, 2 setae medially, 2 setae distally; second vein with 8–9 setae including 1–2 basal to vein fork; clavus with 6 veinal setae including one seta at base. Tergites I–II fully sculptured medially, III–VI with faint lines between median setae; VIII with comb long but irregular, spiracles large ( Fig. 117 ).

Measurements (holotype, in microns). Body length 1150. Head, length 90; width across eyes 125. Pronotum, length 115; maximum width 165. Fore wing, length 560; median width 35; first vein longest seta in basal row 20. Tergite IV S1 setae 12. Tergite IX, MD setae 10; PM S1 setae 80. Tergite X PM S1 setae 65. Antennal segments III–VIII, 40, 30, 30, 42, 10, 15.

Male unknown.

Specimens examined. Holotype female macroptera, Queensland, Lamington, Werrikimbe , fogging Nothofagus moorei , 10.xii.1990 ( R.Kitching).

Paratypes: 7 females taken with holotype.

Comments. Judging from the shape of the head, but despite the enlarged spiracles on tergites I and VIII, this species with 8-segmented antennae is not related to the grass-living members of Anaphothrips . It possibly lives on the leaves of the trees from which it was obtained by insecticide fogging. The pale fore wing with transverse shaded band is particularly unusual.
