A new species of Phaenocarpa Foerster (Hymenoptera: Braconidae: Alysiinae) from Brazil parasitizing Neosilba perezi (Diptera: Lonchaeidae)

This paper provides the description of Phaenocarpa neosilbae sp. n. (Braconidae: Alysiinae) reared from larvae of Neosilba perezi (Romero Ruppel, 1973) (Diptera: Lonchaeidae) in Brazil. Diagnostic characters are figured and the key to the Neotropical species of Phaenocarpa (Arouca Penteado-Dias, 2006) is modified to include the new species.
