Abstract. Eight new species of Casinaria Holmgren, 1859 are described: Casinaria castanea sp. nov. and Casinaria rubens sp. nov. from South Africa, Casinaria sellata sp. nov. from South Africa and Kenya, Casinaria kittenbergeri sp. nov. from Uganda, Casinaria papuensis sp. nov. from Papua New Guinea, Casinaria coloratilis sp. nov., Casinaria russea sp. nov. and Casinaria vesca sp. nov. from Taiwan. The Afrotropical species of the genus are overviewed, and an identification key provided. Additionally, the first reports of Casinaria granulicoxis (Seyrig, 1935) from South Africa, Casinaria albipalpis (Gravenhorst, 1829) from Sweden and Casinaria kriechbaumeri (Costa, 1884) from Cyprus are given.

INTRODUCTION MATERIAL AND METHODS

asinaria Holmgren, 1859 is a species-rich Taxonomy and nomenclature follow Yu & C genus of family Ichneumonidae, subfamily Horstmann (1997) and Yu et al. (2012); hence, Campopleginae. Prior to this study 106 valid spe- complete nomenclatural history and list of syno- cies were known worldwide, 33 of them occurring nym taxa are not repeated here. The morpholo- in the Oriental, 28 in the Western Palaearctic, 18 gical terminology is based on Gauld (1991) and in the Eastern Palaearctic, 11 in the Australasian, Gauld et al. (1997); however, regarding wing two in the Oceanic, two in the Afrotropical, 20 in veins, the corresponding terminology of Townes the Nearctic, and nine in the Neotropical regions (1969) is also indicated for better comparability (Yu et al. 2012, Riedel 2018, Vas 2019a, b).
