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. concolorata is known only from females, and these are unique in having antennal segment III dark brown with only the extreme base paler. The ventral tubercle on the fore tibia is exceptionally large.
