About the Notify Us category

Your opportunity to tell us and the scientific community about newly published taxa, including novel species, genera, and higher taxonomic ranks.

Although we do our best to incorporate new proposals and taxonomic changes by relying on public resources such as NCBI Taxonomy and LPSN, there may be significant delays in the propagation of new names in these databases. We encourage users to share their newly published taxa for timely inclusion in GTDB. We will need the taxon name, publication DOI, and genome sequence accession of the designated type.
