[4] It was described by Irenäus Eibl-Eibesfeldt and Friedmann Köster in 1983, originally under the genus Taenioconger.

[5] It is a marine, tropical eel which is known from the eastern central and southeastern Pacific Ocean, including Colombia, Costa Rica, the Galapagos Islands in Ecuador, and Panama.

[1] It dwells at a depth of 10 to 30 m (30 to 100 ft), and lives in large, nonmigratory colonies in clean, sandy substrates.

Males can reach a maximum total length of 70 cm (2 ft 4 in).

[4] The fish is named in honor of German ichthyologist Wolfgang Klausewitz, who visited the Galápagos Islands where this eel occurs, with the senior author in the 1950s.
