61 New Rove-Beetle Species Hiding in Plain Sight Highlight the Vast 'Linnean Shortfall'

A team at the Natural History Museum of Denmark led by entomologist Aslak Kappel Hansen has formally described 61 new species in the rove-beetle genus Platydracus from China — more than doubling the previously catalogued Chinese diversity of the group in a single paper — in the May 15, 2026 issue of Insect Systematics and Diversity. The integrative taxonomic revision combined museum-collection morphology with COI-barcode sequencing of 412 specimens drawn from holdings going back to the 1880s and from recent fieldwork in Yunnan, Sichuan and the Hengduan Mountains. Many of the new species are several centimetres long and strikingly coloured, dramatising the so-called 'Linnean shortfall' — the gap between the roughly two million catalogued species and the estimated total in nature, which for rove beetles alone may exceed three hundred thousand.
