Taxonomy This 'genus' was erected under the rules of the Phylocode, which does not recognize ranks or type species. The name is here adopted as valid since it is clearly of the genus group rank (encompassing at least two named species, G. barretti and G. hentscheli), but its position in the present classification is controversial. Phylocode and Linnean classifications show fundamental differences. The 'definition' of Depressiogeodia is quoted from the original paper:
Depressiogeodia (nomen cladi novum): (stem-based) the most inclusive clade containing Geodia barretti Bowerbank, 1858 and not Geodia gibberosa Lamarck, 1815 and Geodia cydonium (Jameson, 1811).
Etymology: From the latin words ‘depressio’ meaning ‘cavity’ and ‘geodia’ meaning ‘geode’. [details]
