Distinguishing features

Female macroptera. Body and legs yellow, antennal segments I–II yellow, III–V increasingly brown at apex, VI–VIII brown; fore wings and major setae pale. Head transverse, transversely reticulate on posterior third, weakly reticulate between ocelli; ocellar setae III just outside anterior margins of triangle; eyes without pigmented facets. Antennae 8-segmented; III–IV with forked sensorium; II without microtrichia; VI weakly pedicellate. Pronotum with irregular reticulation, posteromarginal setae thickened but no long setae. Mesonotum boldly reticulate. Metascutum boldly reticulate, sometimes with weak internal markings; median setae on anterior third of sclerite, campaniform sensilla present. Fore wing first vein with about 8 setae on basal half and 4 setae on distal half, arranged irregularly; second vein with up to 12 setae including 1–3 setae basal to vein fork; clavus with 7–8 veinal setae and one basal seta; wing setae all more or less spatulate. Tergites III–VII without sculpture medially, lateral thirds with up to 12 rows of stout, dentate microtrichia, sculpture extending just mesad of setae S2; VIII with comb of moderately long fine microtrichia; tergite IX major setae with apices chisel-shaped.

Male macroptera. Similar to female; tergite IX with 3 pairs of short stout setae dorsally, and one pair of longer stout setae posterolaterally; sternites III–VII with slender 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. parsonsiae, but several species have an intermediate condition with segment VI bearing a partial and often oblique transverse suture. Spatulate setae, as on the fore wing of A. parsonsiae, are found also on the thorax and head of a few other Australian species of Anaphothrips.
