From editor or global species database
Classification Not valid as Annelida: Polychaeta, where it was first placed in WoRMS, and belongs elsewhere. Morphological similarity to the Spirorbinae is suggested to be a result of evolutionary convergence. Representative of fossil order Microconchida Weedon, 1991, currently thought to belong to the lophophorates along with bryozoa and phoronids. "Only six microconchid genera have so far been established: Annuliconchus (Silurian), Palaeoconchus (Late Ordovician-Devonian), Polonoconchus (Middle Devonian), Microconchus (Devonian-Triassic), Helicoconchus (Early Permian) and Punctaconchus (Jurassic) ..."

Editor's comment An early spirorbiform "spirorbid" from the Paleozoic, and thus suspect as spirorbid, see Weedon (1994) [details]
