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.

Related and similar 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 withMegalurothrips, in particular the presence of a pair of small setae dorsally at the apical margin of the first antennal segment. O. australis females cannot be distinguished from females of several other species in this genus, but the males are readily distinguished by the paired elongate tubercles on the ninth tergite.
