Distribution

Africa: easternmost part of West Africa, from the Sassandra River, Ivory Coast, in the west to the Shari River, Central African Republic, in the east; and southwards up to the Kribi River in Cameroon (Ref. 88135).

Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 9; Anal spines: 0; Anal soft rays: 12; Vertebrae: 45 - 49. Diagnosis: This species is distinguished from all other Hepsetus species by the following unique combination of characters: number of lateral line scales low, 43–51; nostril-lower jaw distance short, 36.6–42.1% of head length; number of gill rakers high, 17–23; number of scales between dorsal fin and lateral line 7.5-9.5; number of scales between adipose fin and lateral line 4.5-6.5; head width broad, 32.8–42.3% of head length; and internasal distance high, 21.9–28.3% of head length (Ref. 88135).

This species seems to prefer upper river courses or small rivers where Hydrocynus species are absent or scarce (Ref. 81278).

IUCN Red List Status (Ref. 115185)

Least Concern (LC)
