William T . Calman in 1904 and 1909 described these common morphological features and introduced the major taxonomic subdivisions of the Malacostraca which are still in use today : he divided the Malacostraca in two subclasses the Phyllocarida and the Eumalacostraca, which is further subdivided into four superorders : Eucarida, Peracarida, Hoplocarida and Syncarida.
Molecular studies by Jarman " et al . " ( 2000 ), Spears " et al . " ( 2005 ) and Meland & Willassen ( 2007 ) ( which was derived from Spears " et al . " ( 2005 ) by adding 22 mysidacean taxa to those 26 taxa ) suggest a phylogeny with some elements similar to that proposed by Richter & Scholtz ( 2001 ), but disprove the monophyly of both the Edriophthalma and the Mysidacea and do not possess a basal eumalacostracan taxa or a basal peracarid taxa ( the Hoplocarida and the Syncarida, respectively in ) : The Amphipoda ( with Spleogriphacea ) form a clade with the Lophogastrida, the Isopoda are in a derived clade with the Cumacea and Tanaidacea, while most importantly the Mysida in all three analyses falls basal to the non-Peracarida subtree, which however has a limited morphological support ( Poore, 2005 ).
