Family BUETSCHLIELLIDAE de Puytorac, n. fam.

With general characteristics of the Anoplophryidae (above), but with differences in the silverline system (kinetal patterns, "systèmes sécants," thigmotactic area, etc.) which especially set its genera apart; ciliature may be spiraled; macronucleus rod-like or dendritic; reproduction palintomic; in polychaete annelids.

[Since de Puytorac is planning to establish this group as a new family, it is appropriate to credit him with its name, but as of the date of the present work where the taxon is first characterized (unless a diagnosis appears elsewhere while this book is still in press).]
