Distinguishing features

Female macroptera. Body, antennae and legs light brown, antennal segments I and III paler; fore wings weakly shaded; major setae on abdomen pale brown. Head slightly wider than long, with transverse anastomosing striae behind eyes; eyes with 6 pigmented facets; ocellar setae III variable in position within triangle. Antennae 9-segmented, III–IV with slender forked sensorium; II without microtrichia; VI short, constricted at base but not pedicellate, suture oblique between VI–VII; IX longer than VIII. Pronotum transverse, almost without sculpture medially; with no long setae. Metascutum reticulate, median setae not close to anterior margin, campaniform sensilla present. Fore wing first vein setae irregular, about 8 setae basally, 2 medially and 2 distally; second vein with 12–14 setae including 1–2 basal to vein fork; clavus with 5–7 veinal setae and one at base. Abdominal tergites II–VIII with no sculpture medially; lateral sculpture lines with small microtrichia, not extending mesad of S2; posterior margin of VIII with about 10 microtrichia on median third but none laterally. Sternites laterally with similar lines of sculpture to tergites.

Male macroptera. Smaller and paler than female; tergite VIII comb apparently absent; IX with two pairs of short stout setae; sternites III–VII each with faint C-shaped pore plate.

Related and similar species

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. The form of the comb on tergite VIII in females of A. geleznowiae is not found in any other species, although the presence in males of large C-shaped pore plates and two pairs of stout setae medially on tergite IX occurs in some other Australian species of Anaphothrips.
