The cosmopolitan genus Zeilleria Bayle has been recognised in Zealandia for some time. Zeilleria spiculata MacFarlan and Campbell, 2003 spans the Triassic-Jurassic boundary. Five further species were described from the Jurassic by MacFarlan (2016) and (2019), plus one form left in open nomenclature. This study recognises a further new species from the Late Triassic and one which is represented by a single specimen and is left in open nomenclature.
