Morphology | Morphometrics
soft rays: 6. Diagnosed from all other congeners except Hypostomus heraldoi by the pelvic-fin unbranched ray length equal to or greater than pectoral-fin unbranched ray (vs. pelvic-fin unbranched ray shorter than pectoral-fin unbranched ray). Differs from H. heraldoi by having pale dots over body and fins (vs. dark dots over body and fins) (Ref. 91066).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00448 - 0.02446), b=3.04 (2.83 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (K=0.1).
Vulnerability (Ref. 59153
): Moderate vulnerability (39 of 100) .
