New genera, species and host plant records of Nearctic and Neotropical Tephritidae (Diptera) 2398 Author Norrbom, Allen L. Author Sutton, Bruce D. Author Steck, Gary J.

This species has been reared from flowerheads of several species of Melanthera in Florida. In Guatemala we collected it at three localities almost exclusively on Viguiera dentata (Cav.) Spreng. , which is a likely host plant, although this needs confirmation by rearing. Both plant genera belong to the Asteraceae : Heliantheae . Material examined. GUATEMALA : El Progreso : Hwy.
