Species

Doumea is a genus of catfishes (order Siluriformes) of the family Amphiliidae. It includes five species [1].

D. alula is from the Congo River basin. D. angolensis originates from the Quanza River system and the interior of Benguella, Angola. D. chappuisi is from the Cavally, Nuon, St. Paul, and Koumba River systems of Guinea, Liberia, and Côte d'Ivoire. D. thysi is known from the Cross River basin of Cameroon. D. typica inhabits the Congo River basin and coastal rivers from Cameroon to Congo.[1]

Species of Doumea have a rather large and tapered body, a pointed head, and a thin caudal peduncle. Thin bilateral osseous peaks are sometimes present on the back and the belly, and are the precursors series of osseous plates observed in the other kinds of Doumeinae. By the shape of the body, these fish are adapted to rapids.[2] Doumea species range in lengths form 6.5–13.2 centimetres (2.6–5.2 in).[3][4][5][6][7]
