Phylogenetic relationships of Niphargus species focusing on new taxa from Switzerland. Highlighted are two new species and a sister species (green: N. luchoffmanni sp. n., blue: N. thienemanni, purple: N. tonywhitteni sp. n.) The tree was constructed using Bayesian inference on COI, 28S rRNA and histone gene sequences. The tree was rooted using Microniphargus leruthi (not presented). On the right side, two haplotype networks (based on COI and ITS) calculated within N. thienemanni and N. tonywhitteni sp. n. species pairs are shown. These networks are based on a higher number of samples (N=10, see Suppl. material 2) compared to the phylogenetic tree. Colours in the networks correspond to colours in the tree.
