The Scotokaryotes is a proposed basal eukaryote clade sister to Diaphoretickes.[2] Likely Scotokaryote groupings include the Metamonads, the Malawimonas and the Podiata.[3] [4] The name comes from the Greek word scotos (dark) due to the complete absence of photosynthetic organisms in this clade, contrasting with Diaphoretickes and Excavata.[2]
An alternative to the Unikont–Bikont division was suggested by Derelle et al. in 2015,[1] where they proposed the acronyms Opimoda–Diphoda respectively, as substitutes to the older terms (Opimoda includes the old 'unikonts', plus some former bikonts; Diphoda includes most of the old 'bikonts', but not all). The name Opimoda is formed from the letters (shown in capitals) of OPIsthokonta and aMOebozoa.
Sarcomastigota Cavalier-Smith, 1983 is a proposed subkingdom (currently shown to be paraphyletic) that includes all members of Opimoda that are not animals or fungi.[5] Sulcozoa Cavalier-Smith, 2012 is a proposed phylum (currently shown to be paraphyletic) within Sarcomastigota that does not include the phyla Amoebozoa (clade) and Choanozoa (paraphyletic), i.e. it includes the proposed subphyla Apusozoa and Varisulca.[6]
