Hidden biodiversity in microarthropods (Acari, Oribatida, Eremaeoidea, Caleremaeus)

Abstract A challenge for taxonomists all over the world and across all taxonomic groups is recognizing and delimiting species, and cryptic species are even more challenging. However, an accurate identification is fundamental for all biological studies from ecology to conversation biology. We used a...
