    Taxonomy from Lynne Bean 2021.
    Archaeomaene tenuis can be easily distinguished from the much more common Cavenderichthys talbragarensis by the more posterior dorsal fin.
    Diagnosis for Archaeomaene tenuis from Bean 2021 (modified from Woodward 1895): “ Same as family with the following additional characteristics. The supraorbital sensory canal has branched (ramified) tubules [*]. The dorsal fin is placed opposite to the anal fin. Pelvic, dorsal and anal fins are without fringing fulcra [*]. There are six uroneurals; the epaxial margin of the caudal fin has a few long basal fulcra and long fringing fulcra extending along the whole margin; both leading margins of the caudal fin have a single principal ray. Scales are elasmoid cycloidal [*]. (An asterisk [*] notes a uniquely derived character or autapomorphy of the genus).”
