. ''Coronacomitas'' was originally proposed by T. Shuto in 1983 as a subgenus of '' Paradrillia'' for ''Paradrillia gemmata''. It showed some resemblance to ''Pleurotoma multiseriata'' Smith, 1877, synonym of '' Epidirona multiseriata'' (E. A. Smith, 1877). It differs however by the position of the anal sinus which is situated on the shoulder slope and not on the shoulder itself.
