Dorsal fin with large black spot on its distal end. Other fins spotted except the anal fin. Head depth, 2.3-3.3 times in SL; body depth 1.9-3.2 times in SL. Belly totally naked except for thoracic plates and a group of small irregular plates concentrated on the anus, just posterior to pelvic-fin insertion. Rictal barbels small, attached to lower lip by small membrane. Stomach indistinguishable; intestine very long, about 14 times in SL. Keeled lateral plates, 29-30 (Ref. 40703).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00159 - 0.00757), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 2.5 ±0.2 se; based on size and trophs of closest relatives
Résilience (Ref.
