A slender Paramormyrops with body depth 14.9-23.0% of standard length (Ref. 81635). The head profile has a distinct concave slope; snout is V-shaped from above (Ref. 81635). In life, the body is a uniform deep chocolate-brown over the back, lighter below; the border of the mouth is often white or lightly pigmented giving the appearance of white lips; fin rays and membranes are darkly pigmented (Ref. 81635).

Habitat and Ecology:

Habitat and Ecology

The Ivindo River bottom is rocky; the habitat is dense forest around the river. There are no records of this fish entering streams and creeks, as it appears to be confined to main river channels. The species is benthopelagic.

Electric Organ Discharge:

EOD is strictly biphasic with an initial head-positive peak followed by a head-negative peak. The initial phase of the EOD is head-positive,
with no head-negative pre-pulse. During the rising phase the slope increases continuously toward the peak, P1, with little or no inflection in the waveform. The head-negative peak follows and then there is a gradual return to the baseline. The duration of the EOD is about 3.1 msec for adult females, 4.8 msec for adult males. The electric organ is composed of electrocytes with non-penetrating stalks innervated on the posterior side (Type NPp).
