Anaphothrips occidentalis Pitkin, 1978: 364

This Western Australian species has been studied from the flowers of various Haemodoraceae around Perth, including species of Conostylus and Anigozanthos (Kangaroo Paws) . It has also been studied from Kangaroo Paw flowers cultivated by commercial wildflower nurseries near Sydney and Gosford (New South Wales). It is a particularly large and dark species, with strikingly bicoloured fore wings, and very large pore plates in males ( Fig. 124 ). It is unusual within this genus for the wide separation medially of the prosternal ferna. The holotype was collected in Western Australia near Busselton, Tuart Forest, from grasses, 28.ix.1967.

Female macroptera. Body and legs dark brown, tarsi yellow also apices of mid and hind tibiae and much of fore tibiae; antennal segments I–II and IV–IX dark brown, III yellow; fore wings pale with a dark submedian band, and a more diffuse dark area subapically on posterior margin; prominent body setae dark. Head as long as wide, smaller than pronotum; cheeks almost straight; mouth-cone long; eyes with 6 pigmented facets; ocellar setae III outside ocellar triangle, just anterior to hind ocelli; only 3 pairs of postocular setae. Antennae 9-segmented; segments III–IV with apex slightly constricted, sensorium forked; II without microtrichia, also III ventrally; VI with narrow pedicel; IX longer than VIII ( Fig. 122 ). Pronotum weakly trapezoidal, medial sculpture weak. Metascutum reticulate, median setae behind anterior margin, MCS present. Prosternal ferna divided medially. Fore wing first vein with about 8 setae basally, then up to 10 setae placed irregularly; second vein with 11 to 16 setae including 1–2 setae basal to vein fork; clavus with 5–6 veinal setae and one basal seta. Abdominal tergites weakly sculptured laterally, without microtrichia; VIII posterior margin deeply concave, without comb ( Fig. 123 ); X longer than IX.

Male aptera. Bicoloured, head and abdominal segments VI–X dark brown, remainder and legs variably yellowish brown; tergite IX medially with two pairs of short stout setae; sternites III–VII with very large Cshaped pore plate ( Fig. 124 ).

Larva II. Body and legs yellow, tergite IX with faintly shaded posterior margin but no teeth; major setae slender trumpet shaped with apex asymmetric.
