Rare South American ground beetles sport unusual, likely multi-purpose antennal cleaners

After 157 years since the description of the South American genus of strange-combed beetles, Nototylus, a second specimen finally has been discovered. Published in the open-access scholarly journal ZooKeys as a species new to science, the beetle comes to address some over a century-old debates, including whether or not strange-combed beetles possess a feature distinct for ground beetles, why that might be, and whether or not they are indeed ground beetles at all.
