More on author: Regan.

Issue
Specimens collected in Paraguay (middle Paraguayan Parana basin) identified as Hypostomus albopunctatus based on morphology ( Weber et al. 1992:13). Mitochondrial D-loop sequences used in a molecular phylogeny of Hypostomus and related genera by Montoya-Burgos and Weber (in press, fig 2; EMBL/GenBank AJ318379).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal 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).

Facultative air-breathing in the genus (Ref. 126274)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00605 - 0.01506), b=3.04 (2.90 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Generation time: 13.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.1).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).
