Caliothrips is a genus of 20 species. Most of these are from the New World, with ten in North or Meso-America and three from Carribean Islands. Four species are from Africa and three from Asia, and two species extend into Australia. C. striatopterus has the abdominal tergites with transverse striae, but unlike C. graminicola the extreme apex of the forewing is white.
