| Abstract | Ciliates of the heterotrich family Folliculinidae are widespread in various habitats and are distinguished by their transparent loricae of various shapes, conspicuous peristomial lobes, and dimorphic life cycles. They usually attach firmly to the surface of substrates, feed on bacteria and microalgae, and play a significant role in energy flow and material cycling in the microbial food web. However, little is known regarding their biodiversity and systematics. In this work, we establish the terminology of the family Folliculinidae and select six crucial features for genus recognition. Based on previous studies, we revise the classification of Folliculinidae, supply improved diagnoses for each of the 33 folliculinid genera, and provide a key to their identification. Moreover, phylogenetic analyses based on small subunit ribosomal DNA (SSU rDNA) sequences revealed that the family is monophyletic and comprises two subclades (subclades I II) which can be identified by the flexibility of their peristomial lobes and the sculpturing of their necks. Furthermore, we investigate the evolutionary relationships of folliculinids using the six chosen generic features.
