Exothrips Priesner

Nineteen species are listed in this genus, of which 12 are from India, five from Africa, one from the Philippines, and one from Europe. No revision or identification system to these has been published, apart from Bhatti (1975) who provided a key to 10 species from India together with an extensive diagnosis of the genus. Rhamphothrips and Parexothrips are considered to be related (Bhatti, 1978), because the females in all three genera share a remarkable condition of having the median two pairs of setae on sternite VII arising close to each other. Mound & Tree (2011) suggested that Exothrips possibly represents a grass-feeding lineage of species derived from Rhamphothrips, in which the head is larger relative to the pronotum, the pronotum is not elongate, and the prosternal ferna do not curve forward medially.
