Remarks . Poore and Lew Ton (1990) rediagnosed the genus and redescribed the type species, Z. caeca Hale, 1946 . This species and the second, Z. rotundicauda Kussakin, 1967 are both from the Southern Ocean. Here, a third is described from deep water at a more tropical latitude. The head of this species and of Z. caeca (confirmed on NMV material) possesses an obvious horizontal groove at the base of antenna 2 reaching back about one third of the head length. The groove is not seen in species of any of the other genera, Cleantis , Cleantioides or Holognathus .
