Female macroptera. Body brown, tarsi and antennal segment III yellow, IV also largely yellow; fore wings light brown with base scarcely paler. Antennae 8-segmented; segment I with paired dorso-apical setae; segments III–IV with apex forming short neck, sensorium forked; V with sensorium base oval, VI with sensorium base expanded. Head wider than long; 3 pairs of ocellar setae present; pair III anterior to hind ocelli, shorter than diameter of an ocellus; postocular setae small, close to posterior margin of eyes. Pronotum with strong sculpture, 1 pair of long posteroangular setae; posterior margin with 4 pairs of setae. Fore tibia with two recurved tubercles at apex, ventrally and laterally. Metanotum reticulate, campaniform sensilla present; median setae arise at anterior margin. Mesofurca with spinula. Fore wing first vein with row of setae irregularly and widely spaced on distal third; clavus with 5 veinal setae and one discal seta. Tergites without sculpture medially; VIII with group of irregular microtrichia anterior to spiracle, posteromarginal comb represented by few microtrichia laterally. Sternites without discal setae, VII with median setae arising in front of margin.
Male macroptera. Similar to female but smaller, large males with ocellar setae III and pronotal posteroangular setae relatively longer than in small males and females; tergites III–VI with no sculpture lines medially, VI with prominent dark lobe medially on posterior margin; tergite IX IX posterior margin with no long processes; sternites without pore plates, IV–VII with small transparent lobe medially on posterior margin.
Odontothripiella is an Australian genus that currently includes 18 described species, with several more undescribed species also known. The genus shares many character states withMegalurothrips, in particular the presence of a pair of small setae dorsally at the apical margin of the first antennal segment. O. hopei males are remarkable within this genus for the presence of a lobe on the posterior magin of tergite VI, for the lack of processes on the posterior magin of the ninth tergite, and for the presence of a median lobe on the margins of several sternites.
