Distinguishing features

Female macroptera. Body brown to dark brown, tarsi and antennal segment III paler; fore wings light brown with base paler. Antennae 8-segmented; segment I with paired dorso-apical setae; segments III–IV with apex forming short neck, sense cone forked; VI with base of sense cone very broadly expanded. Head wider than long; 3 pairs of ocellar setae present; pair III anterior to hind ocelli, shorter than side of ocellar triangle; postocular setae small, close to posterior margin of eyes. Pronotum with 1 pair of long posteroangular setae; posterior margin with 4–5 pairs of setae. Fore tibia with 2 recurved tubercles at apex, ventrally and laterally. Metanotum reticulate, campaniform sensilla present; median setae arise at anterior margin. Mesofurca with spinula. Fore wing first and second veins with complete row of setae; clavus with 6 veinal setae. Tergites without sculpture medially; VIII with group of irregular microtrichia anterior to spiracle, posteromarginal comb represented by a few microtrichia laterally; tergite IX posterior margin with pair of slender processes laterally. Sternites without discal setae, VII with median setae arising in front of margin.
Male not known.

Related species

O. bispinosa is known from a single female that was collected with the type series of O. australis. This female is distinguished from O. australis only by the presence of a pair of processes laterally on the ninth tergite, and Pitkin (1972) suggested that it might be an aberrant, intersex, individual of the common species. Odontothripiella is an Australian genus that currently includes 18 described species, with several more undescribed species also known. The genus shares many character states with Megalurothrips, in particular the presence of a pair of small setae dorsally at the apical margin of the first antennal segment.
