Mitogenome recovered from a 19 th Century holotype by shotgun sequencing supplies a generic name for an orphaned clade of African weakly electric fishes (Osteoglossomorpha, Mormyridae)

Images of recently collected Heteromormyrus specimens from which DNA sequences are used in this study A Heteromormyrus pauciradiatus SAIAB 85120_RM, Lucala River above Kalendula Falls, Kwanza Basin, Angola. Partial COI sequence from this specimen is identical to that recovered from H. pauciradiatus holotype B Heteromormyrus pauciradiatus SAIAB 84683_RM, Lucala River at N’dalatando Farm, Kwanza Basin, Angola C Heteromormyrus tavernei RMCA Vert 2018-032-P-0047 tag no.
