The transcription of the Arabic terms and names is often ambiguous. In the literature the locality is called Hakel, Hâkel, Hackel, Haquil or Haquel. Taxonomy from GBIF.org. Alternative combination: Beryx vexillifer Pictet 1850. Diagnosis for the genus Ctenothrissa from Woodward 1899, p. 490: "Head large; trunk deeply fusiform and laterally compressed, but ventral border of abdomen flattened. Maxilla robust and arched, with two large supramaxillary bones; mandible deep, a little prominent, and gape of mouth not extending behind the middle of the large orbit; minute teeth on the margin of the jaws. Preoperculum only slightly expanded; operculum and suboperculum, deep and narrow. Vertebrae from 30 to 40 in number, half being caudal. Pe]vic fins much enlarged and inserted far forwards; dorsal fin much deepened, occupying about half of the back; anal fin small; caudal fin deeply cleft. Scales pectinated, large and regularly arranged, none enlarged or thickened, and no dorsal or ventral ridge-scales ; lateral line conspicuous." References: Woodward, A.

Characteristic for Eurypholis (meaning "broad scale") are the three large scales directly behind the head. References: A. S.
