Etymology: Parmaturus: parma (L.), from parme (Gr.), small shield; oura (Gr.), tail, presumably referring to upper edge of caudal fin “armed with modified” scales (per Garman 1913) (See ETYFish); albipenis: albus (L.), white; penis (L.), copulatory organ, referring to white claspers, which contrast strongly against dark brownish body coloration (See ETYFish).
