Nogueira, A. Williston and J.A. Alves-Gomes0 A new species of electric knifefish from the rio Negro, Amazon basin (Gymnotiformes: Hypopomidae, Microsternarchini). Proc. Acad. Nat. Sci. Phil. 164(1):213-227. (Ref. 104297) Saks, L.0 Estonian Common Names, Rank 2.

It also occurs in black-water streams along the middle part of the rio Negro Basin (Amazon). Along stream margins, it occurs in well oxygnated waler and prefers weak current with abundant submerged vegetation, roots and leaf litter. In areas with stronger current, this species tends to inhabit submerged trees and tangled roots of epiphytic plants. Variation of physico-chemical water parameters taken in 2002-2007: conductivity 9.0-22.2 µS/cm, temperature 25-26°C, ph 4.01-5.0 and dissolved oxygen 4.12-7.10 mg/L. Stomach contents of one specimen contains parts of zooplankton. Associated genera of gymnotiforms species collected in the area were Brachypopomus and Hypopgus (Ref. 104297). Cox Fernandes, C., A.

The electrolytes appear to be large, consist of 1-2 bilateral pairs of columns rows parallel to the axis of the body. Accessory electric organ absent on head or humeral region (Ref. 104297).
