Microgastrinae (Hymenoptera: Braconidae) of Reunion Island: a catalogue of the local species, including 18 new taxa and a key to species

Microgastrine wasps (Hymenoptera: Braconidae) are primary parasitoids of Lepidoptera. Some of them parasitise major economic pests and have been largely used for biocontrol programs. We revise here the fauna of Reunion Island: 34 species were recorded, belonging to 13 genera. One genus and 18 species are newly described: Dodogaster gen. nov, Apanteles minatchy sp. nov., A. pashmina sp. nov., A. romei sp. nov., Cotesia xavieri sp. nov., Dolichogenidea ashoka sp. nov., D. broadi sp. nov., D. lumba sp. nov., D. uru sp. nov., D. villemantae sp. nov., Distatrix yunae sp. nov., Dodogaster grangeri sp. nov., Exoryza safranum sp. nov., Glyptapanteles chidra sp. nov., Nyereria ganges sp. nov., N. mayurus sp. nov., Parapanteles covino sp. nov., P. darignac sp. nov. and Wilkinsonellus narangahus sp. nov.. On the remaining 16 species, 12 are new distribution records. Finally, Glyptapanteles antsirabensis (Granger) comb. nov., G. ficus (Granger) comb. nov., G. subandinus (Blanchard) comb. nov., and Venanides curticornis (Granger) comb. nov. are reassigned from the traditionally defined Apanteles genus to these respective genera. A key to all genera and species is provided.

Afrotropical Ophioninae (Hymenoptera, Ichneumonidae): an update of Gauld and Mitchell's revision, including two new species and an interactive matrix identification key.

Abstract The revision of the Afrotropical Ophioninae is updated, based on the examination of about 800–900 individuals in the South African and European museum collections. A robust interactive matrix key was built to provide quick and reliable identifications. The key is available online at http://www.waspweb.org. Two new species are described: Dicamptus maxipol sp. n. and Enicospilus gauldetmitchellorum sp. n. Numerous new distribution and biological records are provided, and noticeable morphological intra-specific variations are detailed. Enicospilus batus Gauld & Mitchell, syn. n. is considered as a junior synonym of Enicospilus luebberti (Enderlein).

Review of the genus Genaemirum Heinrich (Hymenoptera, Ichneumonidae, Ichneumoninae) with interactive identification keys to species

Abstract We describe Genaemirum phagocossorum Rousse, Broad & van Noort, sp. n., a new ichneumonine parasitoid wasp reared from Eucalyptus nitens logs infested by the cossid moth Coryphodema tristis, which is considered a major pest of forestry and food crops in South Africa. This is the first plausible host association for the genus, and fits with the host association predictions of Heinrich. Two further undescribed species were found in the collections of the Natural History Museum in London and are described as Genaemirum phacochoerus Broad, Rousse & van Noort, sp. n. and Genaemirum fumosum Broad, Rousse & van Noort, sp. n. An identification key to the eight known species and a diagnosis for each species are provided, including photographs of all the primary type specimens. Online Lucid interactive identification keys are available at: http://www.waspweb.org.

Revision of the Afrotropical Lycorininae (Ichneumonidae; Hymenoptera) II. Three new Lycorina species and additional distribution records

Three new Afrotropical Lycorina species are described: L. horstmanni sp. nov., L. jacksonfive sp. nov. and L. riftensis sp. nov. The description of L. globiceps is expanded to include the large variability of the colour pattern. New distribution records are provided for L. fici and L. globiceps. An illustrated dichotomous key, and an online interactive matrix key available on www.waspweb.org, are provided for the identification of the seven known Afrotropical Lycorininae species.

Revision of the Afrotropical Phaeogenini (Ichneumonidae, Ichneumoninae), with description of a new genus and twelve new species

Abstract We revise the 10 genera and 23 species of the tribe Phaeogenini (Ichneumonidae: Ichneumoninae) known to occur in the Afrotropical region. We describe the following 13 new taxa: Kibalus Rousse, van Noort & Diller, gen. n.; K. toro Rousse, van Noort & Diller, sp. n.; K. mubfs Rousse & van Noort, sp. n.; Arearia oxymoron Rousse & van Noort, sp. n.; Chauvinia nyanga Rousse & van Noort, sp. n.; Dicaelotus asantesana Rousse & van Noort, sp. n.; D. hoerikwaggoensis Rousse & van Noort, sp. n.; D. tablemountainensis Rousse & van Noort, sp. n.; Heterischnus mfongosi Rousse & van Noort, sp. n.; H. mkomazi Rousse & van Noort, sp. n.; Lusius flummox Rousse & van Noort, sp. n.; Tycherus amatola Rousse & van Noort, sp. n.; and T. nardousberg Rousse & van Noort, sp. n. New distribution records: Heterischnus africanus (Heinrich, 1936) from South Africa, Tanzania and Uganda; H. krausi Schönitzer, 1999 from Rwanda; Lusius tenuissimus (Heinrich, 1938) from Democratic Republic of Congo, Malawi, Nigeria, South Africa, and Zimbabwe. A doubtful record of Aethecerus foveolatus Gregor, 1940 from Sao Tome is additionaly reported in the appendix. We provide illustrated diagnoses and identification notes. Online interactive dichotomous and matrix Lucid keys to genera and species are available at http://www.waspweb.org.

Belesica madiba and Cremastus tutui (Ichneumonidae: Cremastinae), two entomological gems from South Africa

The Afrotropical cremastine fauna (Hymenoptera: Ichneumonidae) is characterized by the near absence of the genus Cremastus, with a single species reported from Madagascar. The fauna is also characterized by the presence of several endemic genera. Among the latter is the exceptional monotypic genus Belesica. We describe two new species from these extremely rare Afrotropical genera, namely Belesica madiba sp. nov. and Cremastus tutui sp. nov.. Both are only known from South Africa.
