Fig. 3 A in Recent progress in reconstructing lophotrochozoan (spiralian) phylogeny

Fig. 3 A hypothesis of lophotrochozoan phylogeny as discussed in this review. This topology shows a summary of different phylogenomic studies (Weigert et al. 2014; Wey-Fabrizius et al. 2014; Schiffer et al. 2018; Marlétaz et al. 2019). *Please note that several taxa formerly regarded to be placed outside Annelida (Echiura, Myzostomida, Orthonectida, Pogonophora, Sipuncula and Vestimentifera) are now firmly placed as annelid ingroups. Annelida relationships are (mostly) well resolved, see discussion in the text and Struck (2019) for review
