Hepsetidae (African pikes)
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); occidentalis: The Latin adjective occidentalis means 'western' or 'westerly' and refers to the distribution of this species, which is the westernmost species of the genus (Ref. 94534).

Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Diagnosis: This species can be distinguished from all other Hepsetus species by the following unique combination of characters: number of lateral line scales high, 49–60; nostril-lower jaw distance high, 40.4–47.6% of head length; number of gill rakers on first arch low, 14–22; number of scales between dorsal fin and lateral line 7.5-9.5; and number of scales between adipose fin and lateral line 4.5-6.5 (Ref. 88135).
Body shape (shape guide): elongated.
The capture, in the Senegal River, of an individual measuring 510 mm SL has been mentioned, but not confirmed; the collections of the Museum of natural History in Paris include a head that is said to belong to a specimen collected in the Cavally River measuring 700 mm TL and wighing 4.000 g (Ref. 2914, 81278).
