Description

Aspredinichthys species are large aspredinids that grow up to about 22.0 centimetres (8.7 in) SL; they are distinguished from all other aspredinids by the characters including having 8 pectoral-fin rays and several pairs of accessory mental barbels present.[4] The two species placed in this genus are very similar in appearance and are most readily separated by the pattern and number of accessory mental barbels.[4]

• Aspredinichthys filamentosus (Valenciennes, 1840) (Sevenbarbed banjo)
• Aspredinichthys tibicen (Valenciennes, 1840) (Tenbarbed banjo)
