Katianna
Katianna is a genus of globular springtails (Collembola: Symphypleona) with worldwide distribution. Members are distinguished by their minute size (approximately 1 mm), hairy antennae, and abundant setae covering the abdomen, particularly toward the posterior. The genus has been recorded across diverse regions including Europe, the Andes, Central Australia, the Caribbean, and Antarctica. A putative undescribed species from the Pacific Northwest, informally designated "Katianna species 10" or "Mtn Dew Katianna," was first documented in 2016 and rediscovered in 2024.
