簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 2; 背的軟條 (總數): 7; 臀棘 1; 臀鰭軟條: 5. Distinguished from all congeners by having bars on the body; and from all examined Pseudancistrus except Pseudancistrus genisetiger and Pseudancistrus papariae by having an incomplete mid-dorsal plate row with 18 plates ( vs. complete with 21-25 plates). Differs from one specimen of Pseudancistrus genisetiger and the holotype of Pseudancistrus papariae by the presence of 18 continuous plates (vs. mid-dorsal row with 14 plates, then a break around the adipose fin and then 2 more plates at the posterior end of the caudal peduncle. Another specimen of Pseudancistrus papariae with complete mid-dorsal row, but plate rows not examined (Ref. 75198).
Facultative air-breathing in the genus (Ref. 126274); Found in water tea-colored river with low conductivity (12 µmho/cm), visibility ~ 2m and moderate current (Ref. 75198).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
