Distinguishing features

Female macroptera. Body and legs yellow with brown markings; tergites II–VIII brown medially and across anterior half; mesonotum and metascutum brown laterally; pronotum with brown markings; antennal segment I white, II dark brown, III and basal half of IV brownish yellow, V–IX light brown; fore wings faintly shaded; tergite IX setae light brown. Head wider than long, with closely spaced sculpture lines behind eyes; eyes with 6 weakly pigmented facets; ocellar setae III just outside ocellar triangle. Antennae 9-segmented; III–IV with sense cone forked, II with three rows of microtrichia; VI not pedicellate, suture between VI–VII oblique. Pronotum with irregular transverse lines of sculpture; posteromarginal setae S1 larger than remaining setae. Metascutal sculpture reticulate, lines with slight craspedal flanges; median setae fine and well back from anterior margin; campaniform sensilla absent. Prosternal ferna almost complete medially. Fore wing relatively broad, first vein with about 15 setae basally, 2 setae medially and 2 setae near apex; second vein with about 16 setae; clavus with 6 veinal setae and one basal seta. Abdominal tergites V–VII with no sculpture medially, II–IV with some lines medially; tergites laterally with up to 10 striae bearing numerous pale ciliate microtrichia with triangular bases, sculpture extending mesad of setae S2 almost to campaniform sensilla; VIII with long regular marginal comb; IX with many transverse sculpture lines. Sternite VII median setae close to posterior margin.
Male macroptera. Similar to female; tergite lateral sculpture lines with distinct craspeda but no microtrichia; IX with median setae not stout; sternites with no pore plates.

Related species

There are 43 species of Anaphothrips known from Australia (Mound & Masumoto, 2009), out of a total of 86 species worldwide (ThripsWiki, 2020). 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 as in A. yalgooi. Although the metascutal sculpture is similar to that of A. geijerae, that species has a clearly transverse suture between antennal segments VI–VII, and also lacks pigmented eye facets.
