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 : 41

Anaphothrips glenysae sp. n.

( Figs 101–105 )

Female macroptera. Body and legs yellow, abdominal tergites III–VII with pair of small brown areas laterally ( Fig. 104 ), III–IV with brown shading medially; antennal segments I–II white, III yellow, IV–V with apex shaded brown, VI–IX brown; fore wings pale. All dorsal setae on head, thorax and fore wings distinctly spatulate; head wider than long, with transverse sculpture behind eyes but ocellar region without sculpture; eyes with 6 pigmented facets; ocellar setae III within triangle ( Fig. 102 ). Antennae 9-segmented; II with few microtrichia, 2 dorsal setae weakly spatulate; sensorium simple or weakly forked on III, forked on IV; VI short, constricted at base but not pedicellate; suture oblique between VI–VII ( Fig. 103 ). Pronotum with irregular sculpture markings, discal setae spatulate ( Fig. 105 ). Metascutum irregularly reticulate; median setae spatulate, on anterior third of sclerite, lateral setae finely setaceous ( Fig. 101 ); MCS present. Fore wing first vein with setal row irregular, 8–11 setae on basal half, 4–6 on distal half, row sometimes almost continuous; second vein with 12–14 setae including one seta basal to vein fork ( Fig. 101 ); clavus with 4–6 veinal setae and one seta at base. Abdominal tergites III–VII with no sculpture medially, median setae closer together than their length; irregular sculpture lines laterally not extending mesad of setae S2; VI–VII with setae S3 as large and spatulate as S4; tergite VIII median setae wide apart, comb with long, slender teeth, lateral setae spatulate; major setae on IX–X pointed.

Measurements (holotype, in microns). Body length 1000. Head, length 75; width across eyes 110. Pronotum, length 100; maximum width 140. Fore wing, length 560; median width 35; first vein longest seta in basal row 20. Tergite IV S1 setae 10. Tergite IX, MD setae 12; PM S1 setae 55. Tergite X PM S1 setae 45. Antennal segments III–IX, 35, 30, 30, 25, 7, 7, 10.

Male macroptera. Similar to female; tergite VIII with long comb; IX with one pair of short setae medially; sternites without pore plates.

Specimens examined. Holotype female, South Australia, Virginia, from Rhagodia parabolica (Chenopodiaceae) , 17.x.2003 (G. Wood).

Paratypes: 16 females 6 males, taken with holotype.

Comments. The simple sensorium on the third antennal segment sometimes has a very small inner lobe that presumably represents the undeveloped inner branch of the normal forked sensorium found in most other species. Similar variation is mentioned below under A. orchis . The major setae in both sexes of A. glenysae are more broadly spatulate ( Fig. 105 ) than on any other member of the genus, including A. exocarpi . In contrast to that species, the eyes have pigmented facets, also the males of A. glenysae have no sternal pore plates and the median setae on tergite IX are short but not stout. The host plant is a common shrub across dry areas of eastern and central Australia.
