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 with Megalurothrips, in particular the presence of a pair of small setae dorsally at the apical margin of the first antennal segment. O. morisoni is known only from a few females, but these differ from all other species in the genus in lacking any long setae on the pronotum.
