Etymology: Hepsetus: Greek, epsetas, -e, -on = boiled, but there is the following sentence: "oí epsetoi" = certain fishes, and also could be related to "psetta" = grouper (Ref. 45335); odoe: The specific name refers to the local names in the Adangme language of Hepsetus specimens in Ghana: 'Akawo nyagbe', which means 'dog-like teeth' and 'akawo' which means 'attacker' or 'predator' (Ref. 88135).

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). Reports from outside this area refer to other species of Hepsetus (Ref. 88135, 93279, 93907, 108775).

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 9; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 12; Wirbelzahl: 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).
