摘要：A new genus and species of thrips, Fourbethrips fiorella, inhabiting stems, petioles and leaf vein gallsof a Melastomataceae from Costa Rica is described. The galls are induced by an unidentified gall midge larva(Cecidomyiidae). This new thrips can be distinguished from other genus and species of Phlaeothripinae by the shape ofthe pelta, the position of maxillary stylets in the head, the reduced and acute anterior pair of postocular setae, the longand capitate posterior pair of postocular setae, the presence of a group of minute setae, and a pair of short ventral setaein the middle area of the abdominal sternites II-VII. The tergites II-VII have a pair of campaniform sensillae.
