tree revealing the polyphyly of Hadromerida. PhyML tree with branches collapsed showing polyphyly of Hadromerida (shown in red) that we propose to abandon; only nodes with > 50 b.s. are shown. This is a subset of the data used in Redmond et al. . *Raspailiidae, *Suberitida, *Stelligeridae and *Tetractinellida include a mix of former ‘hadromerid’ taxa as well as taxa from other orders.
