Figure 1

Bayesian phylogeny of Lysmata and other related genera based on mitochondrial 16S sequences. Highly variable alignment regions have been removed by GBlocks using less stringent criteria. Clade support values are shown along the corresponding branches (Bayesian Inference/Maximum Likelihood/Maximum Parsimony). Asterisks indicate 100% clade support for all three phylogenetic methods. Numbers before sample locations represent the number of specimens sequenced. Superscript numbers indicate which sequences/taxa are represented on the tree (see Tree Identifier in Table 1). Colored lines indicate Lysmata species. The orange clade represents those with a one-segmented (short) accessory branch, the red clade represents those with a multisegmented (long) accessory branch and the green clade represents those with a one-segmented unguiform (unguiform) branch. We define specialized cleaner shrimp as species with white legs and antennae and bright body coloration. The Hippolysmata correspond to the short accessory branch species. Species with an unguiform accessory branch were described after the synonymy of Hippolysmata with the genus Lysmata.
