Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 6; Spine anali: 4; Raggi anali molli: 10 - 11; Vertebre: 47 - 49. The species is distinguished from its congeners by the following set of characters: with a dark anteriorly oblique blotch in the humeral region, its anterior limit slightly ahead of vertical through the spinelet, and its posterior limit at vertical through the base of second branched dorsal-fin ray; 47-49 total vertebrae; 8-11 retrorse triangular, broad-based and strongly inclined dentations confined to basal three-fourths of pectoral-fin spine posterior margin; presence of an unpigmented region dorsally and ventrally adjacent to the dark midlateral stripe; maxillary barbels reaching at least the caudal fin insertion; the longest ray of dorsal-fin 18.7-22.5% SL; subequal caudal-fin lobes; dark midlateral stripe narrow, from pseudotympanum to the caudal-fin insertion, dorsal region of body without dark stripes; dorsal fin with hyaline stripe near base, followed distally by a dark stripe, then another hyaline stripe and distalmost two-fifths dark (Ref. 118150).
Body shape (shape guide): elongated; Cross section: oval.

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00397 - 0.01825), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  4.0   ±0.6 se; based on size and trophs of closest relatives
Resilienza (Fonte Biblio. 120179):  Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (58 of 100). 🛈
