Etymology: Tatia: Because of Mr. C. Tate Regan (Ref. 45335);  britskii: Named for Dr. Heraldo Antonio Britski, who collected the type material, for his significant contributions and pioneer studies on the systematics of the catfish family Auchenipteridae..

Short description Morfologia | Morfometria

Spine dorsali (totale): 1; Raggi dorsali molli (totale): 5; Raggi anali molli: 10; Vertebre: 32 - 33. Centromochlus britskii can be diagnosed from all members of Centromochlinae, except Gelanoglanis nanonocticolus, by the absence (vs. presence) of adipose fin. It differs from G. nanonocticolus by having two pairs (vs. one pair) of mental barbels, premaxillary tooth patches anteriorly united (vs. separated) and mouth gape straight and short (vs. large and sinuous). It is distinguished from congeners Centromochlus altae, C. existimatus, C. heckelii, C. perugiae, C. reticulatus, C. romani and C. meridionalis by having seven branched anal-fin rays (vs. 5 or 6). It further differs from C. altae, C. existimatus, C. heckelii and C. perugiae by lacking anterior nuchal plate (vs. present); from C. meridionalis and C. romani by having anterior margin of dorsal-fin spine with serrae (vs. dorsal-fin spine smooth); from C. existimatus and C. heckelii by having shorter pectoral-fin spine 20.7-22.7% of SL (vs. 29.3-41.6% of SL). Among species group that share the absence of anterior nuchal plate and seven branched anal-fin rays (i.e, C. punctatus, C. schultzi, C. macracanthus, C. bockmanni, C. simplex), the new species Centromochlus britskii differs from both C. schultzi and C. macracanthus by having smooth (vs. with denticules) posterior border of dorsalfin spine; and from C. punctatus by the morphology of male modified anal fin, specifically, the last branched anal-fin ray progressively shorter than anterior most (vs. last ray abruptly reduced, size half that of preceding one and visible only through dissection) (Ref. 103263).

Biologia     Glossario (es. epibenthic)

Found in areas with rocks and rapids near cofferdams in the main channel of the upper rio Paraná. Stomach contents include insect larvae, including Chironomidae, and other invertebrate fragments. Attains sexual maturity at about 3.3 cm SL (Ref. 103263).

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=0.00490 (0.00197 - 0.01219), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
