Figure 1 in Phylogenetic analyses of a new freshwater amphipod reveal polyphyly within the Holarctic family Crangonyctidae, with revision of the genus Synurella

Figure 1. Maximum- likelihood phylogeny acquired from concatenated dataset (18S ribosomal DNA and COI) using IQTREE. Node support for each of the three support methodologies used is indicated by shaded circles placed on nodes; weakly supported nodes are not marked. Results of four species delimitation analyses (bPTP, GMYC, ASAP and ABGD) are presented to the right of the tree for members of the genus Sicifera. Vertical lines to the right of the tree illustrate both major clades within the family and biogeographical realms occupied by members of the Crangonyctidae. The line illustration depicts a male Sicifera cahawba. Abbreviations: ABGD, automatic barcode gap discovery; ASAP, assemble species by automatic partitioning; bPTP, Bayesian Poisson tree processes; GMYC, generalized mixed Yule coalescent; PP, posterior probability; SHaLRT, Shimodaria–Hasegawa approximate likelihood ratio test; UFBS, ultrafast bootstrap. New taxa and new combinations indicated.
