Phylogenetic position of Heteromormyruspauciradiatus and other taxa of interest within subfamily Mormyrinae, inferred from cytochrome b and other markers. Maximum likelihood phylogenetic tree calculated in RAxML of 113 mormyrin OTUs, including all nominal mormyrin genera, from alignment of 4209 bases of mitochondrial cytochrome b, 12S, 16S and nuclear rag2 and rps7 intron. Rooted with Myomyrusmacrops. Dataset is from Sullivan et al. (2016) to which was added all publicly available Hippopotamyrusansorgii species complex cytochrome b sequences with the addition of sequences from Heteromormyruspauciradiatus holotype NMW 22417, the Hippopotamyruslongilateralis holotype, Paramormyropstavernei, an undescribed species from the Inkisi River in D.R. Congo and several sequences from H.aff.szaboi from the Zambezi and Kabompo rivers, Zambia. Asterisks indicate taxa represented by cytochrome b sequences only. Genus Hippopotamyrus is shown to be diphyletic with type species Hippopotamyruscastor clustering with Hippopotamyruspictus separately from the Hippopotamyrusansorgii species complex clade containing the holotype of Heteromormyruspauciradiatus. The latter clade we reclassify as Heteromormyrus. Full tree with nodes uncollapsed available as Suppl. material 3. OTU names and colors match those used in Mutizwa et al. (2021).
