Revision of the afrotropical oberthuerellinae (cynipoidea, liopteridae).

The Afrotropical Oberthuerellinae are revised, and new dichotomous and multi-entry keys to the species of Oberthuerella, Tessmannella, and Xenocynips are provided. All previously described species in these genera are redescribed; descriptions are augmented by color images of the holotype for each species. The following 11 species are described as new: Oberthuerella cyclopia Buffington & van Noort; Oberthuerella eschara Buffington & van Noort; Oberthuerella kibalensis van Noort & Buffington; Oberthuerella pardolatus Buffington & van Noort; Oberthuerella sharkeyi Buffington & van Noort; Oberthuerella simba Buffington & van Noort; Tessmannella copelandi Buffington & van Noort; Tessmannella kiplingi Buffington & van Noort; Tessmannella roberti Buffington & van Noort; Xenocynips rhothion Buffington & van Noort; and Xenocynips ronquisti Buffington & van Noort. We provide identification keys to the genera and species occurring in the Afrotropical region. Online dichotomous and interactive Lucid keys to genera and species are available at http://www.waspweb.org/Cynipoidea/Keys/index.htm.
