Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 13 - 14; Afterflossenweichstrahlen: 10 - 11; Wirbelzahl: 34. Distinguished from all members of the genus Characidium, except Characidium serrano (upper rio Uruguai basin), in having 8-11 incomplete oblique bars on body sides, extending upwards and downwards from the lateral line and independent of the 8 or 9 dorsal transverse bars which usually are present in Characidium species. Can be differentiated from Characidium serrano in having a wider body width (12.2-15.7%) and lower number of perforated scales on lateral line (32-35) vs. 8.7-11.1% in SL and 37-39 scales in Characidium serrano (Ref. 74998).
Body shape (shape guide): fusiform / normal.

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=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
