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); lineatus: The species name lineata, from the Latin linea, line or thread, refers to the typical horizontal bands visible on the flanks (Ref. 93279).

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Diagnosis: Hepsetus lineatus can be distinguished from H. kingsleyae by a larger number of lateral line scales, 50–64 vs. 45–51, and lower number of gill rakers, 12–18, exceptionally 20 in one specimen, vs. 17–23; and by a larger head width, 32.8–46.7 vs. 26.4–35.6% of head length, and larger internasal distance, 21.5–29.3 vs. 15.6–23.3% of head length; the latter two characters are positively allometric (Ref. 93279). Hepsetus lineatus can only be distinguished from H. akawo by a larger number of lateral line scales, 50–64 vs. 43–51, and a smaller number of gill rakers, 12–18, exceptionally up to 20, vs. 17–23 (Ref. 93279). Hepsetus lineatus can be distinguished from H. odoe by a combination of a large internasal distance, 21.5–29.3 vs. 19.5–25.3% of head length, and a small distance between nostril and lower jaw, 36.8–44.4 vs. 40.4–47.6% of head length; both latter characters are positively allometric (Ref. 93279). Hepsetus lineatus can be distinguished from H. cuvieri by a higher number of gill rakers, 12–20 vs. 8–13, a lower number of scales between the dorsal fin and lateral line, 7.5–9.5 vs. 10.5–11.5, a lower number of scales between the adipose fin and lateral line, 4–5.5 vs. 6.5–7.5, and also by a greater head width, 32.8–46.7 vs. 27.8–40.4% of head length, and smaller internasal distance, 21.5–29.3 vs. 27.8–40.4% of head length; latter two characters positively allometric (Ref. 93279).
