Description

 The Liopteridae are represented in the Afrotropical region by two subfamilies: Oberthuerellinae and Mayrellinae, with the former having been recently revised by Buffington and van Noort (2012) and the latter by Liu et al. (2007). An identification key to Afrotropical liopterid genera was published in Buffington and van Noort (2012) and is also available online at: http://www.waspweb.org/Cynipoidea/Keys/index.htm . The other two liopterid subfamilies, Liopterinae and Dallatorrellinae, are restricted to the Neotropical and Indo-Australasian regions respectively (Ronquist 1995).
