Cromadorida insertae sedis. This genus was initially placed in Microlaimidae (Allgen, 1954). Then it was transferred to Cyatholaimidae (Gerlach and Riemann, 1973) without explanation. It has however features not matching the family Cyatholaimidae as its amphid is round. Therefore it is placed to Chromadorida ensertae sedis.
