Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal soft rays: 6. Distinguished from members of Hypostomus cochliodon group, except H.
hemicochliodon, by having bifid non spoon-shaped teeth and with the lateral cups not fused to the mesial one (vs. spoon-shaped teeth with lateral cups usually fused to the mesial one). Differs from other congeners by the combination of the following characters: dark spots over body and fins; absence of keels on pterotic-supracleitrhum, pre-dorsal plates and on lateral series of plates; deeper body and a pair of parallel moderate keels on predorsal plates; . abdomen completely plated; presence of small-sized and close-settled dark spots (equal to smaller than eye pupil) on dorsal region of head, trunk, and fins; and presence of three pre-dorsal plates bordering supraoccipital (Ref. 91066).
Facultative air-breathing in the genus (Ref. 126274)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00450 - 0.02327), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
