Thysanoptera in Australia

Recognition data

Distinguishing features

Female macroptera. Body and legs yellow, antennal segments II–VIII increasingly brown; fore wings pale. Antennae 8-segmented, III–IV with apical neck bearing forked sensorium. Head slightly wider than long; 3 pairs of ocellar setae, pair III between posterior ocelli and about as long as one ocellus; 4 pairs of small postocular setae in transverse row; maxillary palps 3-segmented. Pronotum transverse, with one pair of posteroangular setae; discal area with almost no sculpture. Metanotum with weak transverse reticulation, median setae behind anterior margin; campaniform sensilla present. Prosternal ferna weakly complete medially; mesofurca with spinula, metafurca with no spinula. Fore wing first vein with 2 widely spaced setae distally, second vein with about 12 setae; clavus with 5–6 veinal and one discal seta; posterior fringe cilia strongly wavy. Abdominal tergites II–VI with narrow posteromarginal craspedum; tergal discal area with little or no sculpture medially; VIII with complete comb of long slender microtrichia, weakly developed ctenidium anterolateral to spiracles. Sternites without discal setae, posterior margins with weakly lobed craspedum; VII median pair of setae arise submarginally.

Male macroptera. Similar to female but smaller; tergite VIII with complete marginal comb; IX with no strong setae; sternites III–VII with transverse pore plate; sternite IX with 30–40 broad-based microtrichia.

Related and similar species

A total of 49 species are listed currently in the genus Oxythrips. However, 12 of these are known only as fossils, and all but two of the other species are from the Holarctic. The genus is probably related to Anaphothrips, but is distinguished because all of the species have a single pair of pronotal posteroangular setae. O. agathidis has the metanotal setae small and well behind the anterior margin of this sclerite, in contrast to the only other member of the genus recorded from Australia.
