REVISION OF THE OTITESELLINE FIG WASPS (HYMENOPTERA, CHALCIDOIDEA, AGAONIDAE) .1. THE OTITESELLA-DIGITATA SPECIES-GROUP OF THE AFROTROPICALREGION, WITH A KEY TO AFROTROPICAL SPECIES OF OTITESELLA WESTWOOD

The Afrotropical representatives of the Otitesella digitata species-gr oup are revised. This group of fig wasps is characterized by the prese nce of two apterous male morphological forms. The species group is cen tred in the Indo-Australasian Region, with a single described species hitherto known from Africa. The females and both male forms of the fol lowing new species are described: O. longicauda, O. nefdti, O. pseudos errata and O. rotunda. The strict host-specificity of these fig wasps provides an indication of their potential distribution based on the di stribution of their Ficus host-species (Moraceae). A key is provided t o all described Afrotropical species of Otitesella, including both sex es and both male morphological forms.
