Diagnosis.

Minute species (0.6-1.3 mm) with body slightly to considerably depressed dorsoventrally; mostly melanic, with brightly coloured appendages; vertex rounded without hyperoccipital carina. OOL variable, but in most species very short, equal to or shorter than diameter of posterior ocellus; antenna 9- or 10-merous, in females with abrupt, 3-merous clava; A8-A10 slightly less abrupt in males. Mesoscutum flattened; notauli (if present) abbreviated anteriorly, gradually dilated posteriorly. Fore wing in most species with short tubular submarginal vein. T2 the largest tergite, with two depressions anterolaterally ( Popovici and Buhl 2010).

Distribution.

Afrotropical: Kenya, South Africa, Tanzania, Togo. Cosmopolitan, excluding Antarctica ( Masner and Huggert 1989; Vlug 1995).

Biology.

Solitary endoparasitoids of weevil ( Coleoptera , Curculionidae ) and leaf beetle ( Coleoptera , Chrysomelidae ) eggs ( Vlug 1995). One species reported to be hyperparasitic through an ichneumonid parasitoid of the pine bud moth Exoteleia dodecella (Linnaeus) ( Lepidoptera , Gelechiidae ) ( Lemarie 1958, 1959). Two species are possibly parasitoids of various gall wasps ( Hymenoptera , Cynipidae ) on Quercus species ( Popovici and Buhl 2010), but they are more likely to be attacking beetle eggs laid in the old, empty cynipid galls ( Notton et al. 2014).

Comments.

There are numerous further undescribed species of Fidiobia from the Afrotropical region present in the collections of SAMC, OSUC and CNCI. These will be treated in a separate revision in collaboration with Ovidiu Popovici (Universitatea Alexandru Ioan Cuza, Iaşi).
