Female macroptera. Body colour brownish yellow with brown markings on tergites I–IV, thorax and posterior margin of head; legs yellow with brown shadings; antennal segment I white, II dark brown, III–IX brown; fore wings weakly shaded along veins; major setae at abdomen apex brown. Head wider than long; transverse reticulation behind eyes, weakly sculptured in ocellar triangle; ocellar setae III inside triangle, no further apart than diameter of first ocellus; eyes with 6 pigmented facets. Antennae 9-segmented; III–IV weakly constricted at apex with forked sensorium; II without microtrichia; VI with short pedicel; suture oblique between VI–VII. Pronotum with irregular sculpture lines; with no long setae, discal setae setaceous. Metascutum reticulate, median setae well posterior to anterior margin, campaniform sensilla absent. Fore wing setae short and stout, first vein with about 6–8 setae basally, 2 medially and 2 distally; second vein with about 10 widely spaced setae; clavus with 4–5 veinal setae but no discal setae. Abdominal tergites II–VII with no sculpture medially, lateral sculpture extending just mesad of setae S2; widely spaced sculpture lines bear a few short microtrichia; tergites IV–VI with distance between median setae scarcely greater than the setal lengths; VIII with long regular posteromarginal comb; spiracular area large.
Male macroptera. Similar to female; tergite VIII with two pairs of small thickened setae medially; sternites without pore plates.
There are 43 species of Anaphothrips known from Australia, out of a total of 79 species worldwide (Mound & Masumoto, 2009). Many of these species have the antennae clearly 9-segmented, others clearly have only 8 segments, but several species have an intermediate condition with segment VI bearing a partial and often oblique transverse suture. A. walchae is similar to A. ceciliin many details, but some of the major setae are shorter and stouter (very weakly spatulate), and the male lacks sternal pore plates.
Known only from Australia.
New South Wales and Queensland.
Feeding and breeding on leaves and flowers.
Ozothamnus diosmifolius, Cassinia sp. (Asteraceae), ladults from eaves of Cissus antartica (Vitaceae).
