Genus and similar species information
This genus comprises more than 100 species, almost all of them from tropics or subtropics. Most of the members have pale body colour, pronotum transversely striate and lateral thirds of abdominal tergites covered with regular rows of minute microtrichia. Some species within this group show a wide range of variation, resulting sometimes in mistaken taxonomic decisions (Mound & Zur Strassen 2001). According to Moulton (1933), Scirtothrips bondari is closely related to Scirtothrips manihoti, but is distinguished by its uniform yellow colour and pale fore wings.
Breeds on leaves. Adults collected on Ipomoea batatas (Convolvulaceae).
