Description:These catfish are slim and elongated and possess
bony projections (plates) that radiate from the vertabrae
reaching all the way to the skin. The projections
expand over the skins surface, forming a shield that
in some species covers much of the body. They lack
a swimbladder so they tend to avoid open waters. Habitat:
The nine species in this genera prefer the upper courses
of the rivers as they are rheophilic (an organism
that prefers to live in fast moving water). Remarks:
D. typica is the type species for this genus
and the holotype was collected in the Doumé
Falls, Gabon, hence the genus name.
River basin and coastal rivers from Cameroon to Congo.
Type locality: Doumé (rivière
