FIGURE 1 in A review of the worldwide distribution of Marenzelleria viridis, with new records for M. viridis, M. neglecta and Marenzelleria sp. (Annelida: Spionidae)

FIGURE 1. Majority rule consensus tree of the Bayesian inference analysis of the combined COI (564 bp) and 16S (307 bp) sequences (871 bp in total) of Marenzelleria spp. rooted with sequences of Malacoceros fuliginosus. Posterior probabilities are shown on the branches. Ma, Mb, Mn, Mv, and Mw denote haplotypes of Marenzelleria arctia, M. bastropi, M. neglecta, M. viridis, and M. wireni, respectively, reported by Bastrop & Blank (2006), Blank et al. (2008), and Blank & Bastrop (2009). WS followed by numbers refer to the voucher specimens deposited at the ZMMU_WS collection. The other two capital letters are followed by the six-digit GenBank accession numbers. The numbers without letters preceding collecting locations are unique numbers from the VIR database linking the individuals on the tree with the sampling data in Table 1 and Table S1; numbers of individuals are separated from sample numbers by dots. Marenzelleria species of Arctic origin are shown in blue; species of Northwest Atlantic origin are shown in purple; specimens from the Oslofjord (Norway) are shown in red.
