Fig. 1 in Resolving the Ophioderma longicauda (Echinodermata: Ophiuroidea) cryptic species complex: five sisters, three of them new
Fig. 1. Phylogenetic relationships and distribution of species of Ophioderma Müller & Troschel, 1840 in the Northeast and Tropical Atlantic Ocean and the Mediterranean Sea. A. Simplified phylogenetic relationships among species of Ophioderma described in this study, modified from Weber et al. (2019). Summary of reproductive strategy: S = broadcast spawner; B = brooder. Correspondence between species names, nuclear genetic clusters and COI mitochondrial lineages is summarized from Boissin et al. (2011) and Weber et al. (2019). C6 is tentatively assigned to O. zibrowii sp. nov. because it occurs far from the type locality and brooding species are expected to have low dispersal rates, leading to low gene flow between populations. B. Distribution of species of Ophioderma in the Northeast and Tropical Atlantic Ocean. C. Distribution of species of Ophioderma in the Mediterranean Sea.
