Fig. 1 in Taxonomic revision and phylogeny of the Ophiocoma brevipes group (Echinodermata, Ophiuroidea), with description of a new subgenus (Breviturma) and a new species
Fig. 1. Phylogenetic reconstruction of Ophiocoma (Breviturma) subgen. nov. (two species of the scolopendrina group as outgroup), estimated by maximum likelihood and neighbour-joining analysis of concatenated sequences of the mitochondrial cytochrome c oxidase subunit I and rDNA 16S (in total 1125 bp). Values at branches indicate bootstrap values for maximum likelihood (above branches) and neighbour-joining (below branches). Specimen codes are resolved in the Supplementary file.
