Opius bucki Costa Lima, 1938
Additional features that facilitate identification of this distinctive species are provided by Wharton and Marsh (1978). See the Opius page for characters that distinguish this species from other Opius that have been reared from Tephritidae.
Subsequently, Wharton (1988) treated Bracanastrepha as a synonym of Utetes, but later, Wharton (1997) noted that several species included by Fischer (1977) in Bracanastrepha did not fit the restricted definition of Utetes. Among these was bucki. Thus, Wharton (1997) returned the species to the genus Opius.
