What is "zemaciinae"

The Zemaciinae, containing only the genus Zemacies, was considered a subfamily of predatory sea snails, marine gastropod mollusks, belonging to the family Turridae, commonly named turrids. Following a revision by Philippe Bouchet et al., the monogeneric subfamily Zemaciinae was abandoned and the genus Zemacies was transferred from Turridae to Borsoniidae. The Zemaciinae were distinguished from other subfamilies by the lack of a radula.
