WebL. welshimeri i L. seeligeri varen ser proposades com a espècies per investigadors de L'Institut Pasteur el 1983. No són causa de malalties, normalment. L. seeligeri és una espècie singular, ja que algunes de les seves soques no hemolítiques naturals són atípiques, un fet que pot dificultar molt la correcta identificació d'aquests bacteris.
