Unknown species Recently there have been records of a new unknown species from the Ppacific Northwest since 2016, rediscovered in 2024, that have been turning up, therefore completing the worldwide range map, because that was the one area that the genus had been lacking. They are currently known within the community as Mtn Dew Katianna, or as former springtail enthusiast and founder of collembola. org Franz Janssens coined before his death in 2021, "Katianna species 10".
