Phylogeny of Hyalella reconstructed by Bayesian analysis. Samples of H. curvispina FC1, H1(1), H2(1), H3(1), H5(1) and H. sp.1 H4(1) are Uruguayan samples. Eleven Hyalella sequences from North and South America and outgroup taxon (sequences of different specimens of the genus Platorchestia sp.) were included. The consensus tree is based on 1758 bp from COI, 12S, 28S, and H3 concatenated datasets. Posterior probabilities are noted next the nodes. Clades from A to F were defined in Zapelloni et al. (2021); Clade G is proposed in the present study.
