The order Pseudoscorpiones De Geer, 1778, often referred to as pseudoscorpion, is a relatively understudied taxonomic group in Korea. Korea has documented only 26 species within 8 families and 13 genera of Pseudoscorpiones, a notably smaller number compared to Japan, which includes 100 species in 13 families and 35 genera, or China, with 168 species in 12 families and 39 genera. Additionally, Korea currently lacks comprehensive information regarding the ecology, behavior, and taxonomic characteristics of Pseudoscorpiones. These highly sensitive soil-dwelling predators dynamically respond to changes in soil conditions, making them potential significant biological indicator species. Furthermore, Pseudoscorpiones are known for their adaptation to lower soil temperatures, rendering them particularly sensitive indicators of climate change impacts. Through this presentation, our goal is to illuminate the ecology, behavior, and taxonomic attributes of Pseudoscorpiones species recorded in Korea. By doing so, we aim to contribute to the future expansion of research in this field and enhance our understanding of these remarkable arachnids.
