''fimbriatus'' means "fringed" referring to the row of tubercules on each cheek.
Identification
''Iluocoetes'' was identified as a separate genus from ''Argentinolycus'' by a number of skeletal differences, although there were fewer than 10 known specimens of ''Argentinolycus''.[ The head and body, especially the upper part, are mid brown in colour with many white spots and there is a dark band extending from the lower front edge of the eye to the upper jaw.][
