Figure 1. Consensus cladogram of flatworms belonging to the genus Cichlidogyrus infecting Lake Tanganyika cichlids.
Cladogram based on the combined nuclear ITS-1, 5.8S rDNA, ITS-2 and mitochondrial COI sequences of Cichlidogyrus parasitizing Lake Tanganyika tropheine cichlids and the outgroups mentioned in Table 2. Statistical support is shown as posterior probability under BI/ML bootstrap. Clades that neither yield a support value of 85 nor of 70 under BI or ML, respectively, were collapsed; “–” indicates that a clade was not recovered in a particular analysis. Tip labels indicate host species with sampling locality and country (C: Democratic Republic of Congo; B: Burundi; T: Tanzania and Z: Zambia) and are coloured according to host genus consistent with Fig. 4. Monophyletic assemblages infecting one host species are boxed. Inlet: Cichlidogyrus parasites (300–400 μm in length) on the gills of Sarotherodon melanotheron Rüppell, 1852 (photograph taken by author A.P.).
