The cheliceral flagellum of some British Chernetidae (Pseudoscorpiones)

Summary Detailed examination of the cheliceral flagella of four British species (C. cimicoides, L. nodosus, A. dubius, and P. scorpioides) belonging to the family Chernetidae shows that the number of blades is stabilized by the protonymph. The morphology and pattern of growth of the blades are described, and the significance of the flagellum as a useful taxonomic character at the generic, if not specific level, is discussed.
