Maximum likelihood tree of a heuristic analysis of the concatenated nuclear genes internal transcribed spacer region and D2D3 region of 28S rDNA (B) of intertidal—(H. disjuncta 1–5 (GD1–5)), deep-sea—(HMMV H. hermesi) and White Sea (WS H. socialis) nematodes. Bootstrap values above each branch correspond to maximum likelihood, maximum parsimony, neighbor-joining and Bayesian analysis. A slash indicates the absence of a branch in the respective analysis. Trees are mid-point rooted
