Metanotum characters were used in the determination of species and supra specific groups within Thysanoptera. Collection specimen study of the structure of the metanotum and the presence of sensillae were viewed by light microscopy. Studies using light microscopy, electron microscopy, and laser confocal showed the so-called striations in the metanotum are really keels, while each of the sensillae, considered in the literature as campaniform sensilae, are not well classified and are more likely to be sensilla placodea.
