Distocyclus conirostris is a species of glass knifefishes found in the deep waters (3.8 to 28.3 m, 12 to 93 ft) of the Amazon basin, lower portions of the Potaro River and in major parts of the Rio Orinoco.

[5] Distocyclus conirostris has a tapering, conical snout with the top and bottom jaws being equal in length.

The eyes are located on either side of a bilaterally compressed, elongated body and are covered by a nictitating membrane.

The mouth of Distocyclus conirostris contains a single row of teeth located on the anterior area of the dentary bone, a trait also unique to this species in comparison to the other members of the Sternopygidae.

It is currently unknown whether or not jamming avoidance response is utilized when encountering other weakly electric knifefish in order to decrease interference between their electrolocation accuracy and their electrocommunication usage.
