Head length 21.0-27.9% SL. Wide interorbital distance, 41.3-51.8% averaging 46.4% of head length. Large tooth plates, width of premaxillary tooth plate 25.9-37.2% of head length (m=29.5), width of vomerine tooth plate 21.0-31.2% of head length. Barbels extremely long, nasal barbel 77.8-187.5%, maxillary barbel 142.9-305.8%, inner mandibular barbell 58.9-128.7%, and outer mandibular barbell 104.3-211.2% of head length. Head rather rectangular in dorsal outline; eyes more laterally located. Frontal fontanelle long and narrow ("knife-shaped").
