Rhyssella is a genus of ichneumon wasps, characterized by small size and distinctive coloration. There are about 10 species in this genus, with notable examples including R. humida and R. nitida, which can be differentiated by coloration patterns. They are parasitoids of woodwasps and contribute to ecosystem dynamics by regulating woodwasp populations.
