Régions where we can find the parasite in the host
The WWF ecozones are based largely on the biogeographic realms of Pielou (1979) and Udvardy (1975). A team of biologists convened by the World Wildlife Fund (WWF) developed a system of eight biogeographic realms (ecozones) (see illustrations) as part of their delineation of the world's over 800 terrestrial ecoregions.
* Nearctic 22.9 mil. km² (including most of North America)
* Palearctic 54.1 mil. km² (including the bulk of Eurasia and North Africa)
* Afrotropic / Ethiopian 22.1 mil. km² (including Sub-Saharan Africa)
* Indomalaya / Oriental 7.5 mil. km² (including the South Asian subcontinent and South east Asia)
* Australasia 7.7 mil. km² (including Australia, New Guinea, and neighbouring islands). The northern boundary of this zone is known as the Wallace line.
* Neotropic 19.0 mil. km² (including South America and the Caribbean)
* Oceania 1.0 mil. km² (including Polynesia, Fiji and Micronesia)
* Antarctic 0.3 mil. km² (including Antarctica).
Heligmonellinae are present everywhere, except in the Oceania and Antartic regions
