Utetes anastrephae ( Viereck, 1913)

( Figure 2F )

Diagnosis. Clypeal margin truncate or concave, occipital carina absent, notauli short and not sculptured, propodeum rugose with irregular transverse carina on anterior half, hind tibia dorso-posteriorly with distinct basal carina, fore wing hyaline with 2 nd submarginal cell long 5-sided, stigma brown.

Comments. Utetes anastrephae was originally described as Opius anastrephae by Viereck in 1913, and was transferred by Fischer (1977) to the genus Bracanastrepha . Wharton (1988) retained Bracanastrepha as a subgenus of Utetes , where the species from the New World with a distinct carina at the base of the posterior tibia were placed. Utetes anastrephae is distributed throughout the Neotropical Region, and may be a complex of closely related species with subtle differences in ovipositor length, body sculpturing and host preference ( Wharton 1997). It is the only species of Utetes recorded from species of Anastrepha . It occurs in 20 states in all five Brazilian regions, and has been found associated with 16 species of Anastrepha and with C. capitata (see Zucchi & Moraes 2008; 2012).
