Bayesian phylogeny of Lysmata and other related genera based on concatenated sequences of 16S/28S genes. 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). Asterisks indicate 100% clade support for both phylogenetic methods. 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. PSH = protandric simultaneous hermaphroditism.
