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 : 23

Anaphothrips callani sp. n.

( Figs 36–38 )

Female macroptera. Body, legs and antennal segments I–II yellow, III shaded brown, IV–IX light brown; wings pale. Head dorsally wider than long; mouth cone long, extending to mesosternum; eyes with 6 pigmented facets; ocellar setae III on anterior margins of triangle. Antennae 9-segmented, III–IV with sensorium forked, II without microtrichia, IX longer than VIII; VI narrowed to base but not pedicellate ( Fig. 36 ). Pronotum transverse, with faint lines of sculpture. Mesonotal anteromedian campaniform sensilla absent or weak. Metascutum weakly reticulate, median setae well back from anterior margin, MCS absent. Prosternal ferna incomplete medially; mesothoracic furca long and slender. Fore wing first vein with about 7 setae basally, and 3 widely spaced setae to apex; second vein with about 9 setae; clavus with 5 veinal setae plus one seta at base. Abdominal tergites with faint sculpture lines laterally but none medially ( Fig. 37 ); VIII with no marginal comb; IX–X relatively long. Ovipositor unusually long.

Measurements (holotype, in microns). Body length 1150. Head, length 65; width across eyes 125. Pronotum, length 110; maximum width 150. Fore wing, length 620; median width 40; first vein longest seta in basal row 15. Tergite IV S1 setae 7. Tergite IX, MD setae 7; PM S1 setae 60. Tergite X PM S1 setae 50. Antennal segments III–IX, 40, 35, 35, 35, 7, 7, 10.

Male macroptera. Similar to female; tergite IX with all setae slender; sternites III–IV with broad, curved pore plate ( Fig. 38 ).

Specimens examined. Holotype female macroptera, Western Australia, Barrow Island , beaten, iv–v.2005 (J. Majer & S. Callan).

Paratypes: Western Australia, 3 females 2 males with same data as holotype ; 1 female with similar data, ix.2006, 1 female ditto, v.2007 ; Perth airport, 2 females from Grevillea ‘Robyn Gordon’, 18.ii.2005; West Binnu, 80km north of Geraldton , 1 female from Geleznowia flowers, 4.viii.1998.

Comments. Adults of this species are particularly pale and weakly sculptured, and thus difficult to study. The female differs from most of the other species with 9-segmented antennae in the absence of a comb on tergite VIII, and the male lacks stout setae on the ninth tergite, and has curved (not C-shaped) pore plates on two sternites only. The host association of this thrips remains unknown, but is likely to involve a species of Myoporaceae or Chenopodiaceae among the arid zone flora.
