From fin rays to DNA: supplementary morphological and molecular data to identify Mormyrus subundulatus Roberts, 1989 (Pisces: Mormyridae) from the Bandama River in Côte d'Ivoire

The genus Mormyrus Linnaeus, 1758 has been well studied in western Africa where five species are currently recognized. subundulatus Roberts, 1989 was described 1989, and, although morphologically and genetically close to rume Valenciennes, 1847, is still considered by the most recent studies as a distinct species. It endemic Côte d'Ivoire Ghana River systems. historically recorded from only three locations but today very likely extirpated one of them threatened remaining two. categorized “Vulnerable B1ab(iii)” IUCN Red List (Dankwa 2020). Although few papers describe precisely morphology electric signal species, they based on limited number samples. In this paper, we present new data morphological characteristics (extending dorsal fin rays count range, which main morphometric criterium distinguish M. rume) Museum samples collected recently kilometers away type locality.
