Maximum likelihood (ML) tree based on the mitogenome sequences of Munida gregaria (KU521508; this study) with 15 other selected species was constructed using MEGA 6.0 software. The bootstrap supports are shown on each node. The following mitogenomes were used in this analysis: Clibanarius infraspinatus (NC_025776; Gan et al. 2015), Pagurus longicarpus (NC_003058; Hickerson & Cunningham 2000), Paralithodes brevipes (NC_021458; Yanagimoto & Kobayashi, unpublished), Lithodes nintokuae (NC_024202; Yanagimoto, unpublished), Paralithodes camtschaticus (NC_020029; Kim et al. 2013), Shinkaia crosnieri (NC_011013; Yang & Yang 2008), Neopetrolisthes maculatus (NC_020024; Shen et al. 2013), Petrolisthes haswelli (NC_025572; Tan et al. 2014), Homologenus malayensis (NC_026080; Hui et al. 2014), Umalia orientalis (NC_026688; Shi et al. 2015), Eriocheir japonica (NC_011597; Wang et al. 2014), Ilyoplax deschampsi (NC_020040; Ji et al. 2014), Scylla tranquebarica (NC_012567; Sangthong, unpublished), Pseudocarcinus gigas (NC_006891; Miller et al. 2005), and Acetes chinensis (NC_017600; Kim et al. 2012).
