Xanthaciura
fruit flies
Xanthaciura is a genus of tephritid fruit flies (Diptera: Tephritidae) established by Hendel in 1914. It comprises 17 described species distributed in the Neotropical region, with eight species recorded from Brazil. The genus belongs to the subfamily Tephritinae, a group whose members are typically associated with Asteraceae flowers for oviposition and larval development. Xanthaciura chrysura has been documented visiting flowers of Aristolochia esperanzae (Aristolochiaceae), representing the first record of the genus associated with a plant family other than Asteraceae.
