Günther of the British Museum of Natural History (BMNH, London)(Ref. 93279).
Eponymy: Mary Henrietta Kingsley (1862–1900) was an ethnographic and scientific writer and explorer. [...] (Ref. 128868), visit book page.

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Diagnosis: distinguished from H. akawo and H. lineata by a narrower head width [26.4–35.6 (mean 33.1) v. 32.8–42.3 (37.0) and 32.8–46.7 (39.4)%HL, respectively] and its narrower internasal distance [15.6–23.3 (mean 20.6) v. 21.9–28.3 (24.7) and 21.5–29.3 (25.1)%HL, respectively]; both characters are positively allometric; distinguished from H. lineata by smaller number of lateral-line scales (45–51 v. 50–64) and higher number of gill rakers [17–23 v. 12–18 (exceptionally 20 in 1 specimen)]; distinguished from H. odoe by smaller number of lateral-line scales [45–51 v. 51–60 (exceptionally 49)] and smaller distance between nostril and lower jaw [33.2–40.9 (mean 38.2) v. 40.4–47.6 (43.1)%HL]; latter character is positively allometric; distinguished from H. cuvieri by higher number of gill rakers (17–23 v. 8–13), lower number of scales between dorsal fin and lateral line (8.5–9.5 v.10.5–11.5), lower number of scales between adipose fin and lateral line (5.5 v. 6.5–7.5) and longer snout [39.3–43.2 (mean 41.0) v. 35.5–38.8 (37.3)%HL]; latter character is positively allometric (Ref. 93279).
