Morphology | Morphometrics
A single, simple-branched barbel arising from the stem. The branch length is equal to or greater than the distal barbel. Heavily pigmented stem except for the part just proximal to terminal bulb; dorsal bulb pigmented except for the medial streak or fork. The terminal filaments extend well beyond tip of the bulb (Ref. 34246).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.4 ±0.8 se; Based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (29 of 100) .
