Genus Hoogenraadia was firstly observed in Africa by Gauthier-Lievre & Thomas in 1958. The characteristic of this genus is the smooth shall with a anterior cap or visor, which makes the aperture a slit opening. Some species of genus Hoogenraadia were believed endemic distributions, which support evidence against the cosmopolitan. The report provides the first description of six species of genus Hoogenraadia - Hoogenraadia africana Gauthier-Lievre & Thomas 1958, Hoogenraadia asiatica Wang & Min 1987, Hoogenraadia cryptostoma Gauthier-Lievre & Thomas 1958, Hoogenraadia humicola Bonnet 1975, Hoogenraadia ovata Bonnet 1975, Hoogenraadia sylvatica Vucetich 1973. According to its own literature and enhanced understanding of the geography of this species, and its ecology. World map shows the distribution of the genus Hoogenraadia. The morphological and morphometric characteristics of the species of this genus were described. The results suggested that the morphology of plagiostoma by testate amoebae have not always adaptive significance.
