Distinguishing features

Female macroptera. Body dark brown, legs with tarsi and apices of tibiae yellowish; antennal segments II and V–VIII dark brown, I light brown, III–IV yellow; fore wings mainly pale; major body setae dark. Head about as long as wide, projecting weakly in front of eyes; eyes with 6 pigmented facets; ocellar setae III just anterior to hind ocelli; postocular setae III displaced behind setal row. Antennae 8-segmented, III–IV with small forked sensorium, II without microtrichia; VI not pedicellate. Pronotum with transverse anastomosing striae; posteromarginal setae slightly longer than discal setae. Metascutum irregularly reticulate, without internal wrinkles; median setae on anterior third of sclerite; campaniform sensilla present. Fore wing first vein with about 6 setae on basal half, 1 seta medially and 2 distally; second vein with about 12 setae including 1–2 basal to vein fork; clavus with about 5 veinal setae and one seta at base. Abdominal tergites laterally with small dentate microtrichia on sculpture and dentate microtrichia on posterior margin; II–VII with sculpture extending just mesad of setae S2, smooth at middle; VIII with long slender posteromarginal comb. Sternites with small dentate microtrichia along posterior margin.

Male macroptera. Similar to female; tergite VIII with long comb; IX with two pairs of short stout setae medially; sternites III–VII each with 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 as in A. incertus, but several species have an intermediate condition with segment VI bearing a partial and often oblique transverse suture. In structure, A. incertus is a typical grass-living species of Anaphothrips.
