neokaryotes neokaryotes the neokaryotes (cavalier-smith 1993) are a proposed eukaryote clade consisting of the unikonts and the bikonts as sister of for instance the jakobea. it arises because the euglenozoa, percolozoa, tsukubea, and jakobea are seen in this view as more basal eukaryotes. these four groups, are traditionally grouped together in the discoba. however, the discoba may well be paraphyletic as the neokaryotes may have emerged in them. neokaryotes amoeba proteus, visible are the contractile vacuole (circular) and the nucleus (somewhat dumbbell-shaped) scientific classification domain: eukaryota (unranked): orthokaryotes (unranked): neokaryotes clades bikont opimoda taxonomy a proposed cladogram is eukaryota tsukubea discicristata euglenozoa percolozoa orthokaryotes jakobea neokaryotes corticata/diaphoretickes/ archaeplastida chromista hacrobia sar bikont scotokaryotes/opimoda/neozoa metamonada malawimonas sulcozoa/podiata/ crums amorphea/ amoebozoa obazoa breviata apusomonadida opisthokonta/choanozoa unikont sarcomastigota
