背棘 (總數) : 3; 背的軟條 (總數) : 7 - 9; 臀棘: 3; 臀鰭軟條: 8 - 10. Diagnosed from Pachychilon macedonicum by having numerous dark brown marks of various shapes and sizes on body (a dark stripe distinct in life in juveniles, rarely in preserved individuals), thick lower lip with a long median lobe, 40-44 + 2 scales on lateral line, and 8-10½ branched rays on anal fin (Ref. 59043). Caudal fin with 19 to 20 soft rays (Ref. 40476).
