Newly discovered species are often threatened with extinction but in many cases have received limited conservation effort. To guide future conservation, it is important to determine the risk of newly described species. Here, we test how time since formal description a linked its threat status obtain better insight into possible and as yet undescribed We compiled IUCN Red List data for 53,808 fr...
