Iotuba chengjiangensis (sometimes mis-spelt Lotuba^[2]) is a 515 million year old Cambrian worm known from the Chengjiang biota.^[3] Originally interpreted as a phoronid, the organism is now recognized as an annelid cage worm affiliated with the Flabelligeridae and Acrocirridae, which Zhang et al grouped together in the new superfamily Flabelligeroidea.^[1]
