That the Microcreagrinae was recovered as paraphyletic in our analysis is not surprising given the number of authors who have commented on the heterogeneity of this subfamily and the potential for paraphyly (e.g., Vachon 1946; Mahnert 1974; Murienne et al.

Remarkably, the former family "Sabellidae" was found to be paraphyletic, necessitating the elevation of the sabellid subfamily Fabriciinae to full family rank (Kupriyanova and Rouse, 2008; Capa et al., 2011).
Molecular and taxonomical studies have supported their independence (Kadereit et al.; 2007; Steffen et al., 2010; Guillo, 2013), but the more recent studies with many sampled species and wide distribution have supported their assimilation, because Salicornia is nested within Sarcocornia, which means that Sarcocornia is a paraphyletic taxon (Steffen et al., 2015; Piraiinen et al., 2017).
