Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Spine anali: 0. Barbel length less than 20% of standard length; barbel with 5 branches apparently arising together from stem; lateralmost pair of branches, which actually arise from base of mediolateral pair, usually shortest; mediolateral pair usually longest; diameter of stem distal to branches greater than that proximal to branches; stem solidly pigmented, pigment extending onto dorsal surface of terminal bulb; terminal bulb elongate and with an unpigmented tip usually directed dorsally; swollen ventrally, its length 2.0 - 2.5 times its thickness; a single terminal filament arising ventral to bulb tip, usually about as long as distal barbel, but occasionally minute.

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=0.00302 (0.00117 - 0.00783), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.3   ±0.8 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 (11 of 100).
Price category (Ref. 80766):   Unknown.
