Leptofoenus is a genus of wasp in the family Pteromalidae, the type genus subfamily Leptofoeninae found in South, Central, and southern North America.[1][2] The genus contains five living species and one extinct species known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.[1] With body sizes ranging from 11–27 millimetres (0.43–1.06 in) Leptofoenus species are larger than nearly all other species in Pteromalidae.[1] The genus bears a notable resemblance to the wasp families Pelecinidae, Gasteruptiidae, and Stephanidae.[1]


All six known species are restricted to the western Hemisphere, most being found in South America and only one reaching North America.
