Following the original publication of this article [1], the authors flagged the following errors: Fig. 3 had been published upside-down; two newly sequenced species (Paradiplozoon yarkandense and Paradiplozoon homoion) had been mistakenly omitted from Figs. 4 and 5; and in the section ‘Gene overlaps’, in the sentence “A relatively large putative overlap between cytb and nad4L was conserved in both species: P. yarkandense = 10 bp, P. homoion = 16 bp (Table 1)”, cox1 had been written instead of cytb.
