The Afrotropical region is a relatively uncontroversial concept conforming to the old Ethiopian region of Sclater and Wallace from the earliest days of zoogeography, with the name changed as of Crosskey and White (1977). As in all the authoritative versions of delimitations, Madagascar and the islands of the western Indian Ocean are included, as is the southern part of the Arabian Peninsula, the South Atlantic islands of Ascension, St. Helena, Tristan da Cunha and Gough, as well as the Cape Verde Islands and the Gulf of Guinea islands (Darlington 1957, Crosskey 1980). Crosskey and White (1977) defined the northern limit of the region by the 10 inch (254 mm) precipitation isohyet. With climate change and aridification this boundary is constantly in a state of flux. For the purposes of the Afrotropical Hymenoptera Initiative we use the boundary between the arid and hyper-arid climatological zones as defined by the World Meterological Organization and United Nations Environment Program derived from mean monthly precipitation and potential evapotranspiration surfaces (Desanker and Magadza 2001; van Noort et al. 2015). This corresponds to the northern edge of the Sahel region bordering with the southern limits of the Sahara desert, a boundary which is usually demarcated by the 150 mm isohyet (White 1983, Fensholt et al. 2013). White (1983) and Linder (2012) further subdivide the sub-Saharan region into cohesive biogeographical subentities based on plant and vertebrate data. Patterns of invertebrate distributions would be expected to correlate with the environmental partitioning of the region (van Noort et al. 2015).
