Genus and similar species information
The genus Charassothrips comprises five species, all of them described from Neotropics and with conspicuous reticulation on head and thorax. The abdominal tergites also bear a well-developed posteromarginal craspedum. C. urospathae can be recognized by the uniformly brown abdomen and the slender and acute fore wing setae. Goldarazena & Mound (2010) provided a key to the world Charassothrips species.
World distribution
Described from Northern Brazil, it is also known from Costa Rica.
Adults studied from inflorescences of Urospatha spp.
Economic importance
Not recorded.
