‘Localimania’ revisited: guidelines for the formation of specific epithets for names of prokaryotes based on names of institutions or their acronyms. A proposal for emendation of Appendix 9 to the International Code of Nomenclature of Prokaryotes Oren, Aharon and Garrity, George M and Schink, Bernhard and Ventura, Stefano,, 67, 1618-1619 (2017), doi = https://doi.org/10.1099/ijsem.0.001816, publicationName = Microbiology Society, issn = 1466-5026, abstract= We here present a survey of the increasing use of the -ensis (-ense) ending for the formation of specific epithets that do not refer to geographical locations but to names of research institutes or their acronyms. To our opinion the use of the -ensis (-ense) ending must be discouraged for such purposes, the formation of nouns in the genitive case being preferred for the formation of such arbitrary epithets. Emendation of Appendix 9 – Orthography to the International Code of Nomenclature of Prokaryotes is proposed with guidelines for the formation of such names., language=, type=
