A, Schematic drawing of conserved elements in the control region of twelve stomatopods. B, Maximum-likelihood tree based on the amino acid alignment of 13 PCGs in the stomatopod mitochondrial genome. A, T = poly T stretch, GA5 = GA-5′-block, GA3 = GA-5′-block, TAm means that the [TA(A)]n-block is present multiple times. Ω = potential hairpin structure. An X in front of the Ω indicates that the conserved motif “TTAT” is present. B, Maximum-likelihood phylogenetic tree based on the amino acid alignment of 13 protein coding genes in the mitochondrial genome of stomatopods. Phylogenetic analyses included a total of 11 genera from 6 different families and 4 superfamilies in the order Stomatopoda: Squilla empusa (NC007444), Squilla mantis (NC006081), Squilloides leptosquilla (NC027178), Lophosquilla costata (MT276143), Oratosquilla oratoria (NC014342), Harpiosquilla harpax (NC006916), Chorisquilla orientalis (MT672286), Taku spinosocarinatus (MT672285), Lysiosquillina maculata (NC007443), Gonodactylus chiragra (NC007442), Gonodactylaceus randalli (MW019425), and Faughnia haani (MW632159). Outgroups included two mysid species (Neomysis japonica (KR006340) and N. orientalis (KC995119), two euphausiid species (Euphausia superba (NC040987) and E. pacifica (NC016184)) and two amphipod species (Metacrangonyx longipes (HE861923) and Caprella scaura (NC014687)
