Comment: Pérez-Losada et al. (2012b) conducted a multigene molecular phylogeny in Chthamaloidea and showedthatthesubfamiliesChthamalinae,Euraphinae and Notochthamalinae are not monophyletic groups. We did not retain these subfamilies and assign all these genera under Chthamalidae . Neither the number of plates nor the number of mandibular, cuticular ‘teeth’ reflects any phylogenetic pattern in Chthamalidae , as reflected in previous subfamily assignments.
