FIGURE 1 in Diversity, taxonomy and phylogenetic relationships of the "Niphargus borutzkyi" ingroup (Crustacea: Amphipoda: Niphargidae) in Western Georgia, SW Caucasus

FIGURE 1. The map of collection sites and the time-calibrated phylogenetic tree (reconstruction) of phylogenetic relationships of the newly discovered species of the genus Niphargus from the Western Georgia, Caucasus. Bootstrap support (upper) and posterior probabilities (below) of the nodes are reported. Blue horizontal bars show the 95% HPD (highest posterior density) of node ages on an arbitrary time scale. Figure of the Niphargus amirani Marin, 2020 is taken from Marin (2020).
