Overview of malacostracan phylogeny. Simplified representation of malacostracan phylogeny, following . The major malacostracan monophyla suggested by these authors (Eumalacostraca, Caridoida, Decapoda, Pleocyemata, Xenommacarida, Peracarida) are marked with horizontal brackets. The taxa Anaspidacea and Bathynellacea are shown together as Syncarida. The peracaridan subtaxa Lophogastrida, Spelaeogriphacea, Mictacea, Tanaidacea, and Cumacea are excluded. Therefore, Amphipoda and Isopoda appear as sister groups. The developmental mode of the taxa is indicated by symbolic drawings at the bottom. The developmental mode is color coded to the branches and the most parsimonious character states of the ancestral lineages are shown. Outgroups are not depicted. Color coding: Direct/pseudodirect development (black); nauplius larva as hatching stage (blue); zoea-like larva as hatching stage (green).
